The document analyzes data from the SPS-3 and SPS-4 studies of the Long Term Pavement Preservation Database to evaluate the effectiveness of rigid and flexible pavement preservation treatments under different site conditions. It considers factors like climate, traffic levels, pre-existing pavement conditions, and treatment age. For each treatment, service life extension is calculated based on performance measures like cracking, faulting, roughness and rutting. The analysis found that thin overlays were most effective overall for extending service life. Certain treatments like crack sealing performed better under high traffic, while joint sealing was generally more effective than undersealing for rigid pavements. However, the document notes that effectiveness depends on the site conditions and performance measures used.

This document summarizes a study on using finite element analysis to model coir geotextile reinforced flexible pavements. ABAQUS software was used to analyze the stress-strain behavior of unreinforced and reinforced pavement sections under static wheel loads. Results showed that placing coir geotextiles at the interface between asphalt and base course layers significantly reduced lateral strains in the pavement layers. Reinforced sections also had reduced horizontal tensile strains. Fatigue life predictions found that coir geotextile reinforcement can extend the life of flexible pavements compared to unreinforced sections.

Determining the rheological properties of asphalt binder using dynamic shear ...
Abstract
This paper aims to study the rheological properties of the binder taken from four years old flexible pavement stretch. The stretch was
divided into six different sections based on the thickness of the surface course. Originally, 60/70 grade asphalt binder was used
throughout the pavement stretch. The binder was obtained from the process of extraction and recovery. Dynamic shear rheometer
(DSR) test was conducted on the recovered asphalt binder to determine the various parameters viz., Complex modulus G*, Elastic and
viscous modulus, Complex viscosity and the phase angle δ. The major pavement distress modes namely, rutting and fatigue cracking
were addressed by these output parameters of DSR. Rutting is caused by permanent deformation of paving mix while fatigue is related
to the energy absorbed during repeated load application to pavement. The test results indicated that the 60/70 binder extracted from
the selected stretches were stiff enough to resist rutting and fatigue failure.

In this research, climatic data for various regions of
Iran were obtained from meteorological organizations in their
original formats and then were converted to ICM1 input files
for MEPDG2 software by algorithms. The major aim of this
research is to assess the environmental effects on fatigue
cracking, so more than 300 analyses were conducted on a
specific pavement with climatic data from various regions of
Iran, since pavement temperature and humidity profile have
important effects on alligator and longitudinal cracking, and
specific pavements don’t have the same performance in all
regions. Lastly, useful solutions will be recommended for
decreasing the deleterious effects of climatic conditions on

Study on the approaches of soil stabilization
This document discusses approaches to soil stabilization. There are two broad categories of soil stabilization: in-situ and ex-situ. In-situ stabilization involves applying stabilizing agents directly to soils on-site, and can be done through deep mixing methods or mass stabilization. Deep mixing methods like wet or dry mixing inject cementitious materials into soils to desired depths to improve strength. Ex-situ stabilization involves removing soils from their original location and transporting them elsewhere for treatment, such as dredging of contaminated sediments. The document provides details on various deep mixing and mass stabilization methods and their applications in soil improvement projects.
Effect of Compaction Moisture Content on Strength Parameters of Unsaturated C...
This document summarizes a study that investigated the effect of compaction moisture content on the shear strength parameters of unsaturated clay soils using triaxial and direct shear tests. Six different clay soil samples from various locations in India were tested at moisture contents of 0.95, 1.00, and 1.05 times the optimum moisture content as determined from standard Proctor tests. Both triaxial and direct shear tests were performed under unconsolidated undrained conditions at strain rates of 0.625 mm/min and 1.25 mm/min. The results showed that cohesion decreases with increasing moisture content while the angle of internal friction is higher at lower strain rates and from triaxial tests compared to direct shear tests.

IRJET- Study on Flexible Pavement Failures and it’s Remedial Measures
This document discusses a study on failures of flexible pavements and remedial measures. It focuses on a 24 km stretch of road from Shahbad to Saha in Haryana, India that experiences heavy traffic. The road is deteriorating due to failures like cracks and potholes. The study aims to establish guidelines to systematically inspect and evaluate pavement failures. It will determine the causes of failures and recommend the best maintenance option. Common causes of failures identified are poor maintenance, drainage, construction quality, and lack of supervision. Proper maintenance and repairs are needed to preserve pavement quality and safety under heavy traffic loads.

The document summarizes a study on evaluating longitudinal skid resistance on pavement surfaces in Bangalore City. Portable pendulum skid resistance testing was conducted on four road stretches under different conditions like dry, wet, with dry sand, and with oil. Texture depth was also measured using the sand patch method. International Friction Index (IFI) values were calculated from the wet skid resistance and texture depth measurements to allow comparison between different testing equipment. The study found skid resistance values decreased in wet, sandy, and oily conditions compared to dry conditions. Correlation charts showed higher skid resistance with increasing texture depth. The IFI standard practice for harmonizing friction measurements taken with different equipment was also summarized.

- 1. Impact of Site Factors on the Effectiveness of Rigid and Flexible Pavement Preservation Treatments Nicholas McDonald, Syed Haider, Ronell Eisma INTRODUCTION OBJECTIVES The objectives of the paper are: 1. To evaluate and understand the effectiveness of pavement preservation treatments on rigid and flexible pavements under varying site conditions. 2. To provide a more cost-effective way of maintaining pavement by applying preservation treatments early on in the life of the pavement section. This development will reduce the cost of maintaining pavement structures in the future by providing the pavement with a longer service life. PAVEMENT SURFACE DISTRESSES Based on the data analysis, on average, thin overlay is the most effective treatment based on service life extension for the SPS-3 treatments. Thin overlay, slurry seal, crack seal, and chip seal were all most effective in the wet no-freeze climatic zones for surface rutting. Crack seal for flexible pavements and joint seal for rigid pavements were the most effective for high levels of traffic. The treatments applied performed better when the pavements had lower levels of pre-existing rutting. In general, joint sealing in SPS-4 was more effective than joint under sealing across all conditions for rigid pavements. Pavement preservation treatments are a necessary tool to address pavement maintenance needs at the network level. These treatments can provide sustainability to pavement structures to increase the service life extension. SITE CONDITIONS LONG TERM PAVEMENT PRESEVERATION DATABASE (LTPP) SUMMARY Longitudinal Cracking Transverse Cracking The data being evaluated are from the SPS-3 and SPS-4 studies of the Long Term Pavement Preservation Database (LTPP). The SPS-3 and SPS-4 experiments deal with pavement maintenance and preventive maintenance effectiveness of flexible and rigid pavements. The focus of this research is to determine the effectiveness of rigid and flexible pavement preservation treatments under various climates, traffic levels, and pre-existing conditions. The goal is to determine the effectiveness among the treatment types for different site factors. The study evaluated over 100 pavement sections located in 25 different states. For each treatment, the pavement service life extension (SLE) was determined based on temporal performance data. The performance measures used were cracking, faulting and surface roughness (IRI) for rigid, and rutting and IRI for flexible pavements. Service life extension is the amount of years gained from the benefits of the treatment compared to the control section. However, the SLE will depend on the performance measures used to calculate it. Climatic Zones WF- Wet-freeze DF- Dry-freeze WNF-Wet no- freeze DNF-Dry no- freeze • There are a variety of conditions or site factors which needs to be considered while determining the service life extension of pavement preservation treatments. • The different site conditions that were considered are: (a) traffic (AADT, AADTT, and 18k ESALs), (b) treatment age, (c) pre-existing conditions, (d) thickness, and (e) climatic zone. Pavement Preservation Treatments SPS-3 SPS-4 Thin Overlay (310) Joint Seal (410) Slurry Seal (320) Joint Under Seal (420) Crack Seal (330) Control (430) Control (340) Chip Seal (350) • This image presents the loads of different vehicles in the traffic mix on a typical highway. Negative service life extension (SLE) indicates that the treatment did not extend service life or there were other errors. Rutting Roughness DATA ANALYSIS This figure shows time series rutting data for different treatments in the SPS-3 experiment. This data can be used to determine SLE for each treatment type. The red line on the graph is the control section, service life extension is determined by when these trends reach the threshold.
