Specifications for Local Agencies
Local agencies can develop their own SUPERPAVE specifications for asphalt pavement projects by critically reviewing Caltrans' 2015 specifications. The 2015 specs include performance-based requirements for aggregate gradation, asphalt binder content and grade, moisture sensitivity testing using the Hamburg Wheel Tracking Device, density and smoothness standards. Local agencies should identify a pavement expert, develop an action plan and timeline, finalize customized changes based on feedback, and collect data to refine their SUPERPAVE specifications.

PILE FOUNDATION-INDIA
This document discusses pile foundations. Piles are structural members made of materials like steel, concrete, or timber that are driven into the ground to support buildings on weak soils. There are two main types of piles: end bearing piles that extend to bedrock, and friction piles that gain support through friction in the soil when no bedrock is present. Pile caps are used to distribute loads from the structure to multiple piles. Reinforcement in the pile cap resists tensile and shear forces. The document provides schematics and comparisons of different pile foundation construction methods.
Pile foundation
The pile foundation uses piles to support walls, piers, and other structures. Piles can be placed individually or in clusters. Piles are used when loose soil extends to great depths, and transfer structural loads to harder soils below through end bearing and side friction. Common pile materials include timber, steel, and concrete. Piles can be load bearing, transmitting loads through end bearing and side friction, or non-load bearing, used as retaining walls or sheeting. Pile capacity is assessed through field load tests or theoretical calculations based on soil properties.

Pile foundation ppt
This document provides information about pile foundations. Pile foundations are used when the soil cannot support building loads and piles are driven deep into the ground until they reach a bearing stratum. Piles can be made of timber, concrete, or steel. They transfer loads from the building to the stronger subsurface layer. The document discusses different types of piles including end bearing and friction piles and explains how pile caps are reinforced to resist tensile and shear forces from heavy loads. Diagrams show how pile foundations are arranged and how piles transmit loads into the ground.

civil enginnering industrial training report
The document summarizes the industrial training completed at the Vinod Nagar Station Yard project site for the Delhi Metro Rail Corporation. Key activities included construction of the double deck stabling yard and boundary wall. For the stabling yard, bored cast-in-situ pile foundations were used, involving surveying, boring holes with a rig, installing casing pipes, adding bentonite solution, lowering the reinforcement cage, flushing, and filling with concrete. Tests were performed on site and in the lab on materials like concrete and soil. The training provided insights into metro construction processes.
Types of Foundation..Sana may matutunan po tayo !
There are two main types of foundation systems - shallow and deep. Shallow foundations include spread footings and mat/raft foundations. Spread footings are individual slabs under columns and walls that spread the structural load over a broad area. Mat/raft foundations use a continuous slab over the entire loaded area and are often used for structures with high or irregular loads. Deep foundations include piles, piers, caissons and compensated foundations that extend below the building. Piles transfer structural loads to stronger soils at depth using end bearing or friction along the pile. Common pile types include concrete, steel and timber piles.

Rapid transit system
This document provides information on rapid transit systems in India. It discusses that rapid transit consists of bus, metro, monorail and light rail systems which generally operate on exclusive rights-of-way. The first rapid transit system in India was the Kolkata Metro in 1984. Growing populations in Indian cities have led to a shift from private to public transportation with metro rail lines now present in several major cities. Delhi Metro commenced operations in 2002 and now has over 140 stations with a total length of 193 kilometers. Bus Rapid Transit systems have also been implemented in cities like Pune and Delhi to provide fast, reliable public transportation.
Delhi metro
The Delhi Metro is a rapid transit system serving Delhi and surrounding areas with a total network length of 183.7 km and 140 stations, including 35 underground stations. It has an average daily ridership of 1.5 million passengers. The network consists of six color-coded lines: Red, Yellow, Blue, Green, Violet, and an Airport Express line, with plans to expand to 413 km by 2021. It is managed by the Delhi Metro Rail Corporation.
Bridge rehabilitation
Bridge rehabilitation covers many complex engineering problems and economic issues. It involves repairing, strengthening, or replacing existing bridges to improve their structural condition and functional capabilities. The main factors that can lead to bridge deterioration include inner bridge factors like design flaws; traffic load factors from increasing vehicle loads and speeds; weather and environmental factors such as pollution and temperature fluctuations; and inadequate maintenance. Bridge rehabilitation aims to address deterioration from these sources and extend the usable life of bridges.

Drilling and producing well
The document provides information about drilling and production wells. It discusses how a production well is drilled using a drilling rig located on an offshore production platform. It then describes the multi-stage drilling process where casing pipes are installed and cemented as drilling progresses to greater depths. Different components of the drilling system like the drill bit, drill pipes, and casing are also explained. The document concludes with discussing the typical sequence of drilling operations.
Pile foundation
The document discusses different types of pile foundations. It begins by explaining that pile foundations transfer structural loads through weak soil layers to stronger layers below. It then describes different types of piles based on their function (load bearing, sheet), material (wood, concrete, steel), and installation method (driven, precast). Key points covered include how end bearing, friction, and composite piles transmit loads differently. The document also lists situations where pile foundations are necessary and advantages/disadvantages of different pile materials.
Foundation & Pile driving equipment
Foundation systems can be either shallow or deep. Shallow foundations include spread footings and slab-on-grade foundations that are embedded a meter or less into the soil. Deep foundations such as piles extend further underground through weak topsoil to reach stronger subsoil layers. Pile drivers are mechanical devices that use raised weights, hydraulics, or diesel hammers to drive piles into the ground to provide deep foundation support. Modern foundation installation equipment includes vibratory hammers, hydraulic presses, and piling rigs of varying sizes suited for different pile diameters and depths.
Shallow foundation(by indrajit mitra)01
Shallow foundations transmit structural loads to near-surface soils and are used when the upper soil layer is sufficiently strong. They include spread, combined, strap, and raft foundations. Design considers factors like bearing capacity, settlement, and water table effects. Plate load tests determine ultimate capacity and settlement by measuring pressure-displacement curves. Terzaghi's theory and IS codes provide design guidance.
Design of staircases
The document discusses the design of staircases. It begins by defining key components of staircases like treads, risers, stringers, etc. It then describes different types of staircases such as straight, doglegged, and spiral. The document outlines considerations for designing staircases like dimensions, loads, and structural behavior. It provides steps for geometric design, load calculations, structural analysis, reinforcement design, and detailing of staircases. Numerical examples are also included to illustrate the design process.

Foundationnotes 121120064719-phpapp01
Foundations transfer structural loads from buildings and bridges to the ground below. There are two main types: shallow foundations, such as spread or strip footings placed on compacted soil below the frost line; and deep foundations like piles that transfer loads through friction or end bearing. Pile foundations include driven piles made of timber, concrete or steel that are installed using pile driving equipment like hammers, leads and compressors. Pile capacity is evaluated through dynamic testing with Pile Driving Analyzers and static pile load tests. Driving records document the installation of each pile.

This document discusses the benefits of Cold In-Place Recycling (CIR) and Full Depth Reclamation (FDR) for road construction and rehabilitation. CIR and FDR involve pulverizing the existing asphalt pavement and a portion of the base materials, mixing them with stabilizing additives, and compacting them to form a new stabilized flexible base that provides increased structural integrity and moisture resistance compared to traditional granular bases. The document emphasizes that CIR and FDR are more cost-effective alternatives to full removal and replacement of roads, and help to create stronger and more sustainable roads for future generations.
Foundation notes
Foundations transfer structural loads to the ground and include shallow foundations, such as spread footings, and deep foundations, such as piles. Piles are driven or drilled deep into the ground to gain bearing capacity from end-bearing or skin friction along their length. Pile driving involves using equipment like hammers, leads, and compressors to install piles, and dynamic testing helps evaluate pile capacity and optimize the driving system. Pile load tests provide a direct measurement of a pile's axial capacity. Proper installation and inspection techniques help ensure foundations perform as designed.
Pipe Bursting Project Considerations

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

- 3. Auger Cast – Continuous Flight Auger (CFA) • Continuous Hollow Screw Auger • Genrates spoils • Designed like CIDH • No displacement • Not common in Calif
- 4. Need for Auger Cast Piles • Soft Clay Site • High Groundwater • Surcharge improvement not always possible • Sound restrictions for driven piles • Environmental restrictions for drilled piles • Contaminated Groundwater/soil (no cuttings)
- 5. Auger Displacement Pile (ADP) • Solid lead with Displacement Tip • Generates little spoils • Designed like Driven Pile • Displacement • Most common in Calif • Morris-Shea, Condon- Johnson, Malcolm, Berkel
- 6. Auger Cast Pile Overview
- 7. Goal of Previous Test Programs by Group Delta • Test Program for Agency Acceptance • Replacement for Driven 14” Concrete Piles • 180-200 Kip Design Loads • 70-100 Kip Liquefaction Down-drag loads • 500-600 Kip Ultimate Capacity • Over 50 Load Tests to date
- 8. Project Location Largest Urban In-fill in US $6 Billion development Former Hughes Aircraft / Runway Facility
- 10. AUGER CAST PRESSURE GROUTED (closed system, continuous grout pressure)
- 11. QC - Installation Record • Improvement from standard record • Real-Time plots of torque, grout pressure and grout take with depth (not time) • Field Verification of embedment depth into target layer • Torque in absolute Kip-ft
- 12. DeWaal Pile • Open System • Concrete Gravity • Conc Feed Pressure by tremmie head
- 13. QA/QC - Installation Record • “Open System” – top open to gravity • DeWaal Pile, Fundex Inspector’s IPad Screen
- 14. Torque as a Target Indicator • Absolute torque analogous to driving energy • Dense Sand/Gravel indicated by 60 Ft-Kips • Good correlation with CPT Qc • Useful for Installation / End Bearing Verification
- 15. Torque vs. Qc
- 16. Typical Compression Test Result
- 17. Typical Tension Test Result
- 18. Load Test – Creep Plot • Modified ASTM Procedure • Held at Design load until less than 0.005 inch/hr. (ASTM is 0.01 inch/hr)
- 19. Long Term Test – 62 days • Tested at Ultimate Load – 602 Kips.
- 20. Pile Exhumation Initial Jack-out Pile Lifting after relief holes drilled
- 22. Exhumed Pile Details Pile “Belly” – Soft Clay Response Pile “Wart”
- 23. Exhumed Pile Details Pile “Swirl” – Sensitive Clay Response Pile “Neck” – low grout at interval
- 24. Pile Tip – In Dense Gravel from 50 feet deep
- 25. Composite of Exhumed Pile
- 26. Pile Coring
- 27. ADP Conclusions • Local Agency Acceptance (DSA, City) • Torque good indicator of bearing (60 ft-kips) – independent of auger type • Electronic Monitoring improved QC and installation verification – better than Gamma or HighStrain • Monitored Grout increment should be no more than 2 feet • Long Term Testing at ultimate load – long term creep • Pile Exhumation verified monitoring and NDT
- 28. Alternate Application Auger Cast Tangent Pile Walls
- 29. Current Pile Installs and Testing Morris Shea DeWaal Piles • 8,000 Piles since 2013 • 50-70 Feet Long • 500-600 Kip Ult. Capacity • 200 Kip Allowable Capacity • Another 2000 for 2 projects starts Nov 2015
