This document discusses finding a suitable correlation between the California Bearing Ratio (CBR) and different index properties for high plastic soil. It reviews existing correlations that have been proposed between CBR and simple field/laboratory tests like the dynamic cone penetrometer (DCP) test and Clegg Impact Value (CIV) test. The goal is to develop a framework for predicting CBR from percentage finer and plasticity index tests, which are simpler and less time-consuming than the CBR test itself. The proposed correlation will be established through graphical analysis of a large number of test results on soil samples collected from different sites in India.

This document summarizes previous research that attempted to correlate California Bearing Ratio (CBR) values with other simple soil properties to provide easier estimation of CBR. It describes correlations developed between CBR and properties such as dynamic cone penetration values, Clegg impact values, liquid limit, plasticity index, optimum moisture content, and maximum dry density. However, it notes that existing correlations are empirical and may only be reliable for the specific soil types and conditions they were developed for. It concludes there is still a need for further study to develop more generalized correlations that can reliably predict CBR for a wider range of soils.

IRJET- Prediction of Cbr Value from Index Properties Of SoilIRJET Journal
This document presents a study that aims to develop models for predicting the California Bearing Ratio (CBR) value of soil from index properties that are quicker to determine than the standard CBR test. The CBR test takes 4 days to complete but engineers need a quicker assessment of soil strength. The researchers collected soil samples and conducted tests like sieve analysis, Atterberg limits, standard Proctor, and CBR to determine properties like liquid limit, plastic limit, optimum moisture content, and maximum dry density. Correlations between CBR and individual properties showed varying strengths. Multiple linear regression analysis was then used to develop prediction models incorporating several properties. The models will help engineers assess soil strength more rapidly.

Abstract
Static and dynamic cone penetration tests are widely used in Foundation engineering for measuring the penetration resistance of the
ground and for relating it to the degree of compaction and safe bearing capacity of soils. In Highway Engineering, Pavement
Dynamic Cone Penetrometer (DCP) is used for rapid in-situ strength evaluation of subgrade and other unbound pavement layers. In
the present studies, an attempt has been made to identify the strength and thickness of different pavement layers of newly constructed
low volume roads in the State of Karnataka, India using dynamic cone penetration studies and was compared with actual
measurements at the site. The evaluation of pavement test stretches was made for a period of two years, and changes in penetration
resistance of different pavement layers were measured. A Software was used to analyze the DCP data and to correlate with field
observation. The results have favoured the possibility of using dynamic cone penetrometer as a quality control and pavement
monitoring tool for low volume roads, eliminating the need for a Benkelman beam or a falling weight deflectometer.

The document presents the results of a study that used linear regression to correlate index properties and California bearing ratio (CBR) values of lateritic soil samples collected from eight borrow pits in Osogbo, Nigeria. Laboratory tests on the samples found good correlations between CBR and properties like grain size, liquid limit, plastic limit, and maximum dry density. Regression equations were developed to estimate CBR values from index properties for preliminary assessments, though actual CBR tests are still needed given the heterogeneous nature of lateritic soils. The CBR values ranged from 64-85% unsoaked and 26-33% soaked. Most samples met specifications for subgrade, sub-base, and base materials, except two had lower soaked CBR

This document summarizes a study on the variation of strength in cohesive soil with moisture content and time. Standard Proctor compaction tests were conducted on a silty clayey soil to determine its maximum dry density and optimum moisture content. Unconfined compressive strength tests were then performed on soil samples compacted at different moisture contents (ranging from 8.6% to 14.6%), and cured for different time periods from 0 to 30 days. The results showed that unconfined compressive strength and initial tangent modulus decreased with increasing moisture content, but increased with curing time, for all moisture contents tested. The study aims to understand how the strength and deformation properties of subgrade soils used in road construction can vary due to

Investigation of Geotechnical Properties of a Lateritic Soil with Saw Dust AshIOSR Journals
This document investigates the use of saw dust ash (SDA) as a stabilizing agent for an A-7-6 lateritic soil. Tests were conducted on mixtures of the soil with 2%, 6%, 8%, 12%, 16%, and 20% SDA by weight. Results showed the liquid limit and plasticity index decreased with increasing SDA content up to 12%, while maximum dry density decreased and optimum moisture content increased. Unconfined compressive strength initially decreased then increased up to a maximum of 164.2 kPa at 16% SDA, around 4 times the strength of the untreated soil. The 12% SDA mixture produced strengths of 118.5 kPa, a plasticity index of 11.6

IRJET- Correlation of CBR with Index Properties of Soil of Kolar Region (...IRJET Journal
This document presents a study that correlates the California Bearing Ratio (CBR) with index properties of soil in the Kolar region of Bhopal, India. Seven soil samples were collected from the study area and tested to determine CBR and index properties including liquid limit, plastic limit, plasticity index, maximum dry density and optimum moisture content. Simple and multiple linear regression analyses were used to develop correlation models between CBR and the index properties. Six single regression models and three multiple regression models were developed with correlation coefficients above 0.8, providing equations to predict CBR based on index properties for soils in the Kolar region.
This document presents a study that developed empirical equations to predict the soaked CBR value of lean clay soils based on index properties, dry density, and unsoaked CBR values. Laboratory tests were conducted on soil samples collected from an existing flexible pavement, which identified the soil as lean clay. Soaked and unsoaked CBR tests were performed at different densities. Three equations were formulated: 1) Using index properties and compaction characteristics to predict soaked CBR, 2) Relating dry density to soaked CBR, and 3) Relating unsoaked CBR to soaked CBR over a range of dry densities. These equations can be used to predict soaked CBR for lean clay subgrade soils.

This document evaluates the use of ultrasonic pulse velocity testing to determine compaction characteristics of expansive clays stabilized with granulated blast furnace slag (GGBS). Standard Proctor tests were conducted on clay specimens with 0-25% GGBS to determine optimum moisture content and maximum dry density. Ultrasonic pulse velocity tests on the specimens showed that velocity increased with GGBS content and dry density up to optimum moisture, then decreased with further water content. Slabs were also cast and tested, showing slightly lower velocities than laboratory specimens. Cores from the slabs validated the densities, demonstrating ultrasonic pulse velocity can be a non-destructive alternative to conventional compaction testing methods.

IRJET-Soil Stabilisation by Utilising Phosphogypsum and Calcium Carbide ResidueIRJET Journal
This document summarizes a study on soil stabilization using phosphogypsum and calcium carbide residue. Black cotton soil samples were mixed with 2%, 4%, 6%, and 8% of phosphogypsum and calcium carbide residue individually, and together. Standard compaction, unconfined compression, and California bearing ratio tests were conducted. Results showed that maximum dry density decreased and optimum moisture content increased with increasing residue content. Unconfined compressive strength and California bearing ratio values initially increased with residue content but then decreased at higher contents. Stabilizing with both residues together gave higher strength values than individual residues. The study demonstrated the potential of using these industrial wastes for economically improving soil engineering properties.

Dynamic Cone Penetrometer Value and California Bearing Ratio RelationshipIRJET Journal
This document discusses research into the relationship between Dynamic Cone Penetrometer (DCPT) values and California Bearing Ratio (CBR) values for different soils. The researchers conducted DCPT and CBR tests on clayey, sandy, and silty soils with varying moisture contents and compaction densities. Previous studies found direct linear relationships between DCPT and CBR values that depend on soil properties. The goal of this study is to determine the DCPT-CBR relationship for different soils and examine the effect of moisture and compaction. Establishing a reliable DCPT-CBR correlation could provide a quicker and cheaper way to estimate soil strength for pavement design.
Correlation between cbr and index propertys of soilRAJESH JAIN
This document discusses correlations between the California Bearing Ratio (CBR) and index properties of soil. It examines several existing correlations between CBR and properties like liquid limit, plastic limit, and maximum dry density. The authors analyze data from previous studies to compare predicted CBR values from two correlations to experimentally measured CBR values. They find that one correlation works better for clayey soils but overestimates CBR for highly plastic clays, while the other correlation predicts lower CBR values than measured across soil types. The authors conclude that the correlations show some agreement with tests for low plasticity clays but need improvement to reliably predict CBR from simple soil properties.
This document summarizes a study that correlated the California Bearing Ratio (CBR) value of coarse-grained soils with index properties and engineering properties.

Simple and multiple linear regression analyses were used to develop correlations between CBR and properties like OMC, MDD, and coefficient of uniformity. A multiple regression equation was developed that could predict CBR with 97.2% accuracy based on OMC, MDD, D60, and D30.

The authors analyze data from previous studies to compare predicted CBR values from two correlations to experimentally measured CBR values. They find that one correlation works better for clayey soils but overestimates CBR for highly plastic clays, while the other correlation predicts lower CBR values than measured across soil types. The authors conclude that the correlations show some agreement with tests for low plasticity clays but need improvement to reliably predict CBR from simple soil properties.
This document summarizes a study that correlated the California Bearing Ratio (CBR) value of coarse-grained soils with index properties and engineering properties. Disturbed soil samples were collected from eight locations in Jabalpur, India and tested to determine CBR, optimum moisture content, maximum dry density, and particle size distribution. Simple and multiple linear regression analyses were used to develop correlations between CBR and properties like OMC, MDD, and coefficient of uniformity. A multiple regression equation was developed that could predict CBR with 97.2% accuracy based on OMC, MDD, D60, and D30. The study concluded that CBR correlates well with properties like coefficient of uniformity and decreases with increased
In the present paper a series of California Bearing Ratio (CBR) tests has been performed in
both soaked and unsoaked condition on field samples collected from road subgrade. Four rural
roads in West Bengal, India have been considered for collection of field CBR sample. From the
experimental data it is found that with time the values of CBR in soaked and unsoaked condition
increases irrespective of types of road subgrade. Based on the present experimental data a
nonlinear power model has been developed to predict field soaked CBR value with time (CBRfst), in
terms of field soaked CBR value at 0 days (CBRfs0 ) and time ‘t’.

Establishing relationship between cbr with different soil propertieseSAT Journals
Abstract
In the flexible pavements sub-grade is considered to be an ideal layer to resist wheel load and its CBR value is considered as the strength measuring parameter. Conducting CBR test is an expensive and time consuming test, moreover it is very difficult to mould the sample at a desired in-situ density in the laboratory. Further, if the available soil is of poor quality, suitable additives are mixed with soil and resulting strength of soil is assessed by CBR value which is cumbersome. To overcome these problems, the other methods such as regression based models (simple & multiple) are used in this study. The soil properties like liquid limit, plastic limit, plasticity index, optimum moisture content, maximum dry density and percentage fineness of the soil (passing 75micron sieve) are determined for the soil collected from different areas of Bagalkot district and the models are developed for correlating soaked CBR value.
Keywords: CBR, regression models, liquid limit, plastic limit, plasticity index, optimum moisture content and maximum dry density.
IRJET- Effect of Roughness of Rectangular Combined Footing based on Ultimate ...IRJET Journal
This document summarizes the results of an experimental study on the effect of roughness of the base of a rectangular combined footing on its ultimate bearing capacity and settlement in cohesive soil. Laboratory tests were conducted on model footings placed in a steel tank filled with locally sourced cohesive soil. Tests were performed with footing bases that were smooth and rough. The tests measured settlement under increasing loads. The results showed that rough footing bases experienced less settlement than smooth bases under the same loads, indicating that roughness improves a footing's bearing capacity and reduces settlement in cohesive soils. Prior research that found soil confinement around footings improves bearing capacity in granular soils is also cited.

This document discusses using ultrasonic pulse velocity testing to determine the strength and stability of soil. Specifically, it examines using this non-destructive testing method on compacted soil samples with different stabilizer contents. The study analyzes how stabilizers like ground granulated blast furnace slag affect the engineering properties of clayey soil. It details the methodology of mixing soil with varying amounts of stabilizer, compacting the mixtures, and then conducting ultrasonic pulse velocity tests to measure the soil's density and modulus of elasticity. Graphs of density and velocity versus water content are used to evaluate the compaction characteristics and determine if ultrasonic testing can provide a fast alternative to standard compaction tests.
The subbase/base thickness of pavement is governed by the CBR value of the subgrade soil along with some other parameters such as traffic intensity, climatic conditions, etc. Dynamic cone penetration test (DCPT) value conducted in the field can be used to estimate the CBR value provided a suitable relationship exists between CBR and DCPT value.
This document studies the use of industrial wastes like crusher dust, aggregates, and ground granulated waste tires (GGWT) as materials for granular subbase (GSB) in flexible pavement construction. Five gradations (GSB11 to GSB15) were developed using different sieve sizes and mixes of crusher dust, aggregates, and 0-2% GGWT by weight were tested. Compaction and CBR tests found that optimum moisture content increased and maximum dry density decreased with higher GGWT content. CBR values increased up to 1% GGWT then decreased. GSB13 with 1.5% GGWT achieved the highest CBR of 58%, meeting requirements for heavier traffic roads. Using industrial wastes

STABILIZATION OF WASTE DUMP USING FLYASHDr. Naveen BP
Bangalore is facing problems due to old municipal solid waste dump yards
situated close to the expanding city as they are in the expansion zone of growing city. These
dump yards needs to be reclaimed for infrastructure development such as roads, buildings and
other needs. To reclaim the old dump sites, it is necessary to know the characteristics of solid
waste, more particularly the geotechnical properties. The characteristics of dumps sites are not
generally suitable for foundations of most types of structures coming on them and their
properties need to be improved. Also their characteristics vary change with aging due to their
degradation. This paper presents the results of stabilization of dumped waste by addition of
pozzolanic material such as fly ash. Laboratory tests such as Direct shear and California
Bearing Ratio (CBR) have been performed on dumped waste with fly ash. It was found that
addition of 20% of fly ash the shear strength of dumped waste has increased considerably. Also
CBR of stabilized waste dumps, which is important in the reclamation of dumped sites, has been
analyzed. It was that CBR of stabilized dumps was higher value for 5 mm penetration than for
2.5 mm penetration and tests were conducted to confirm the same. It was observed that the
improvement in CBR is promising and further studies are required to improve to the material to
form suitable for foundations.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
