Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 676: Intelligent Soil Compaction Systems explores intelligent compaction, a new method of achieving and documenting compaction requirements. Intelligent compaction uses continuous compaction-roller vibration monitoring to assess mechanistic soil properties, continuous modification/adaptation of roller vibration amplitude and frequency to ensure optimum compaction, and full-time monitoring by an integrated global positioning system to provide a complete GPS-based record of the compacted area--

Principles and Practice of Ground Improvement
Author: Jie Han
Publisher: John Wiley & Sons
ISBN: 1118259912
Category : Technology & Engineering
Languages : en
Pages : 432
Book Description
Gain a stronger foundation with optimal ground improvement Before you break ground on a new structure, you need to analyze the structure of the ground. Expert analysis and optimization of the geo-materials on your site can mean the difference between a lasting structure and a school in a sinkhole. Sometimes problematic geology is expected because of the location, but other times it's only unearthed once construction has begun. You need to be able to quickly adapt your project plan to include an improvement to unfavorable ground before the project can safely continue. Principles and Practice of Ground Improvement is the only comprehensive, up-to-date compendium of solutions to this critical aspect of civil engineering. Dr. Jie Han, registered Professional Engineer and preeminent voice in geotechnical engineering, is the ultimate guide to the methods and best practices of ground improvement. Han walks you through various ground improvement solutions and provides theoretical and practical advice for determining which technique fits each situation. Follow examples to find solutions to complex problems Complete homework problems to tackle issues that present themselves in the field Study design procedures for each technique to simplify field implementation Brush up on modern ground improvement technologies to keep abreast of all available options Principles and Practice of Ground Improvement can be used as a textbook, and includes Powerpoint slides for instructors. It's also a handy field reference for contractors and installers who actually implement plans. There are many ground improvement solutions out there, but there is no single right answer to every situation. Principles and Practice of Ground Improvement will give you the information you need to analyze the problem, then design and implement the best possible solution.

Report of the Workshop on Intelligent Compaction for Soils and HMA
Author: David J. White (Ph. D.)
Publisher:
ISBN:
Category : Pavements, Asphalt
Languages : en
Pages : 160
Book Description
This document summarizes the discussion and findings of a workshop on intelligent compaction for soils and hot-mix asphalt held in West Des Moines, Iowa, on April 2-4, 2008. The objective of the meeting was to provide a collaborative exchange of ideas for developing research initiatives that accelerate implementation of intelligent compaction (IC) technologies for soil, aggregates, and hot mix asphalt. Technical presentations, working breakout sessions, a panel discussion, and a group implementation strategy session comprised the workshop activities. About 100 attendees representing state departments of transportation, Federal Highway Administration, contractors, equipment manufacturers, and researchers participated in the workshop.

Geotechnics for Roads, Rail Tracks and Earth Structures
Author: A. Gomes Correia
Publisher: CRC Press
ISBN: 9789026518447
Category : Technology & Engineering
Languages : en
Pages : 300
Book Description
The intent of this work is to present an international overview of advances in geotechnical engineering referring to design and construction of road pavements and rail tracks for high-speed trains. It seeks to influence the international pavement and railway engineering community to move away from merely empirical procedures towards a sophisticated approach based primarily on proven theoretical concepts.;The volume covers compaction technology in construction, properties of geomaterials relevant for design and construction, effects of grain crushing, freezing-thawing problems, and embankments for highways and high-speed trains (in-situ tests, modelling, design, monitoring and specifications). It contains 16 contributions including two special lectures: one about high embankments instead of bridges and bridge foundations in embankments, and a second one about impacts on geotechnical engineering from findings of laboratory stress-strain tests on geomaterials.

Proof Rolling of Foundation Soil and Prepared Subgrade During Construction
Author: Phillip Dunston
Publisher:
ISBN: 9781622604807
Category :
Languages : en
Pages :
Book Description
16. AbstractProof rolling provides a method to examine the entire subgrade surface as a compliment to standard random acceptance testing. Proof rolling requires established criteria that account for the interplay of equipment parameters and soil characteristics, technique, and other specifics of the project to allow for proper interpretation. The researchers concluded that proof rolling is not appropriate for determining soil elastic properties, while it can reveal in situ strength properties. No information from state highway agencies (SHA) publications or interviews reports using proof rolling other than for the evaluation of the subgrade. Only eight SHA¿s have notable specifications or other supporting documents containing significant guidance or criteria. The requirements provided for use of either of two equipment types¿tandem-axle rear dump trucks and chariot-style rollers¿and a range of evaluation criteria based on soil type and whether the project is new construction or re-construction. Recommendations provided fall within parameters practiced by states that have the most well-developed specifications and practices for proof rolling. The recommendations include: evaluation is of the subgrade only and the equipment shall be either a tandem-axle rear dump truck or a tri-axle rear dump truck (with raised third axle) loaded to a minimum gross weight of 20 tons. The chariot-style roller loaded to a minimum gross weight of 40 tons could be alternatively specified. The test shall be a single pass in each traffic lane with the passing criteria of a 1¿ deflection for new construction and 1⁄2¿ deflection for re-constructed or stabilized subgrade, as well as the absence of pumping and cracking.
