This book was released on 1997 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state department of transportation (DOT) construction, geotechnical, materials, and pavement system design engineers, engineering geologists, and research engineers, and others concerned with the constructibility of new pavements over existing subgrades. The synthesis describes current practice for the stabilization of existing subgrades to improve constructibility during interstate pavement reconstruction. It presents information regarding the methods available to evaluate and improve subgrade conditions for the purpose of meeting the constructibility requirements of a reconstruction project. This report of the Transportation Research Board presents data obtained from a review of the literature and a survey of the state DOTs. The synthesis reports on: subgrade evaluation methods including sampling, laboratory, and in-situ test methods, as well as assessment of existing drainage systems; constructibility factors such as existing and proposed pavement types, available equipment, and cost effectiveness of various subgrade stabilization techniques; methods of subgrade improvement including mechanical and chemical stabilization, use of recycled and waste materials, the use of geosynthetics in reinforcement and drainage applications; and construction methods with an emphasis on innovative approaches such as novel sequencing of construction traffic, use of lightweight equipment, and robotics. In addition, several case histories describing applicable pavement reconstruction projects are presented. Finally, suggestions to possibly improve the practice and the identification of research needs are also presented.

Book Synopsis Geotechnical Aspects of Pavement Engineering by : Nishantha Bandara
Download or read book Geotechnical Aspects of Pavement Engineering written by Nishantha Bandara and published by Momentum Press. This book was released on 2018-02-25 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Familiarity with geotechnical aspects of pavement engineering is essential for the practicing pavement engineer. When designing pavements, accurate characterization of the existing subgrade condition becomes a crucial task. In the past, traditional geotechnical exploration and testing methods have been used to characterize existing subgrade conditions. However, with the introduction of the Mechanistic-Empirical (ME) pavement design, there is a need for improved and more appropriate methods of subgrade characterization, for prediction of future pavement conditions with better accuracy. Hence, this handbook will present a useful tool for practicing pavement engineers.
Book Synopsis Influence of Subgrade Improvement and Non-uniformity on Pavement Performance by : Tyson David Rupnow
Download or read book Influence of Subgrade Improvement and Non-uniformity on Pavement Performance written by Tyson David Rupnow and published by . This book was released on 2004 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis contains results from three projects describing self-cementing fly ash stabilization of RAP-soil mixtures, stabilization of limestone screenings for use as a structural layer in road construction, and finite element modeling results of various subgrade materials including self-cementing fly ash stabilized subgrade, natural subgrade, granular subbase, and hydrated fly ash. The first project shows that self-cementing fly ash stabilization of RAP-soil mixtures is economically feasible and structurally capable of supporting construction traffic. The increase stiffness from the addition of self-cementing fly ash increases capacity ensuring long term pavement performance. Addition of self-cementing fly ash increases the consolidated shear strength about five times. The second project shows construction operations and field results proving that stabilization of limestone screenings is viable, cost effective, and produces an adequate structural layer for road construction. The measured moisture-density curves for manufactured sand and limestone screenings are about the same, and the moisture-strength curves show a dramatic decrease in strength beyond the optimum moisture content for strength. Durability testing concluded that CKD stabilized manufactured sand and limestone screenings are not viable construction alternatives, and the addition of class C fly ash with CKD significantly increased the durability of the mixtures. The third project concluded that a link exists between subgrade non-uniformity and pavement performance. Field testing, with the DCP, Clegg Impact Hammer, nuclear density gauge, and GeoGauge, and statistical analysis of subgrade materials concluded that granular subbase, self-cementing fly ash treated subgrade, and HFA decrease the variability of field results. Finite element modeling analysis proved that a link exists between subgrade non-uniformity and pavement performance. Uniform modeling conditions produced lower average deflections and stresses increasing pavement life. Statistical analysis concluded that modeling uniform subgrade conditions produce average stresses that have less variability than those for non-uniform modeling conditions. Pavement response reliability increased with the addition of uniform subgrade, proving that subgrade non-uniformity influences pavement performance.
Book Synopsis Measuring in Situ Mechanical Properties of Pavement Subgrade Soils by : David E. Newcomb
Download or read book Measuring in Situ Mechanical Properties of Pavement Subgrade Soils written by David E. Newcomb and published by Transportation Research Board. This book was released on 1999 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to pavement and geotechnical design and research engineers, geologists and engineering geologists, and related laboratory personnel. It describes the current practice for measuring in situ mechanical properties of pavement subgrade soils. The tests conducted to measure the mechanical properties of soil strength and stiffness are the primary topics, and these are discussed in the context of design procedures, factors affecting mechanical properties, and the variability of measurements. Information for the synthesis was collected by surveying U.S., Canadian, and selected European transportation agencies and by conducting a literature search. This TRB report provides information on existing and emerging technologies for static and dynamic, and destructive and nondestructive testing for measuring in situ mechanical properties of pavement subgrade soils. Correlations between in situ and laboratory tests are presented. The effects of existing layers on the measurement of subgrade properties, and soil spatial and seasonal variability are discussed. Most importantly, the use of soil properties in pavement design and evaluation are explained. New applications or improvements to existing test methods to support the use of mechanistic/stochastic-based pavement design procedures are also explained.

Book Synopsis Pavement Subgrade Performance Study by : Vincent C. Janoo
Download or read book Pavement Subgrade Performance Study written by Vincent C. Janoo and published by . This book was released on 2003 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanistic design or evaluation of pavements requires fundamental material properties and material failure criteria as a function of load and environmental effects such as temperature and moisture content. The strength or weakness of a pavement structure is based on the performance of the subgrade. The current subgrade failure criteria used in many mechanistic design/evaluation methodologies were surmised mainly from tests that did not consider the effects of subgrade soil type or moisture content. Because of these limitations the current FHWA-sponsored Subgrade Performance Study was designed to investigate and upgrade the failure criteria of subgrade materials. The project plans to study the effect of subgrade type and moisture content on the failure criteria. This international study includes testing at the U.S. Army Cold Regions Research and Engineering Laboratory where test sections are being constructed using four subgrade types and three moisture contents and subjected to accelerated loading. The sections are instrumented with stress strain moisture and temperature sensors. In this study the ambient temperature is held at around 20 deg C. This report provides an overview of the test program and testing procedure. Subsequent reports will detail the construction of each test section the data acquired and the results.
