Book excerpt: The objectives of this study were to determine how to incorporate the increase in stiffness of stabilized subgrade in the design of (Flexible?) pavement, and to examine the longevity of subgrade stabilization. Pavement sites that included stabilized subgrade across the state of Ohio were selected for field measurements. The field work included measurements made with portable seismic properties analyzer (PSPA), falling weight deflectometer (FWD), core collection, and dynamic cone penetrometer (DCP) at multiple locations at each site. Original construction records, soil logs, and soil classification data were consulted as well. The FWD and DCP data were used to determine the resilient moduli and layer coefficients of aggregate base and stabilized subgrade and the resilient modulus of the unstabilized subgrade. Several methods of data analysis were used, including back calculation using finite element modeling from the FWD data and estimation of modulus from the DCP data and soil classification using procedures given in the 1993 AASHTO Guide for Design of Pavement Structures, ODOT's Pavement Design Manual, and a report for ODOT written by Eddie Chou [2004]. As borne out by FWD and DCP measurements, both cement stabilization and lime stabilization resulted in significant long term increases in the modulus of the stabilized subgrade relative to the unstabilized subgrade. The modulus and stiffness of the base is also increased because it is confined by the stabilized soil underneath and the pavement on top. The significant increase in the modulus of the base and stabilized subgrade has an impact on the thickness design of pavement.

Available in PDF, EPUB and Kindle. Book excerpt: The Midwest States Accelerated Pavement Testing Pooled Fund Program, financed by the highway departments of Missouri, Iowa, Kansas and Nebraska, has supported an accelerated pavement testing (APT) project to compare the performance of stabilized clayey embankment soil when Portland cement, fly ash, lime and a commercial product were used as stabilizing agents. The project aimed to improve the practices related to the design of flexible pavements when the top of the subgrade is improved by chemical stabilization. The experiments were conducted at the Civil Infrastructure Systems Laboratory (CISL) of Kansas State University. The test program consisted of constructing four flexible pavement structures and subjecting them to full-scale accelerated loading test. The study indicated that cement and lime are the most effective stabilizers for the studied soil. These stabilizers resulted in lower vertical compressive stresses at the top of the subgrade and lower rut depth at the pavement surface than the fly ash-treated soil. After more than two million axle load repetitions, the pavement with cement stabilized embankment soil exhibited much less surface cracking than the pavement with fly-ash stabilized embankment. The commercial product proved not to be effective in stabilizing the non-sulfate clayey soil used in this experiment, when the embankment is constructed at the same moisture content and compaction level as for the other three chemicals. The unconfined compression strength measured on laboratory prepared samples of soil stabilized with the commercial chemical compound was very similar to that of the untreated soil.

Download or read book Evaluation of Low-quality Recycled Concrete Pavement Aggregates for Subgrade Soil Stabilization written by Masoumeh Tavakol and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recycled concrete aggregate (RCA) is the byproduct of the demolition of concrete structures and pavements. An estimated 140 million tons of concrete waste is produced annually in the United States, most of which ends up in landfills. The use of RCA to replace quarried aggregates in paving projects is one way to utilize these materials and alleviate concerns regarding this increasing waste stream. RCA usage prevents waste concrete disposal into landfills, resulting in more sustainable use of mineral aggregate sources, and may further reduce costs associated with paving projects. However, the inferior physical properties of RCA, such as the presence of recycled mortar, complicate the incorporation of RCA into new concrete mixtures. State highway agencies such as the Kansas Department of Transportation are facing further issues with RCA from D-cracked pavements, raising the question if D-cracked aggregates should be used in paving operations. No known work has evaluated the effect of RCA from D-cracked pavements in subgrade soil stabilization. This study stabilized a low-plasticity clay in Kansas using RCA and three stabilizing materials (lime, Class C fly ash, and a combination of Portland cement and fly ash). Candidate mixtures with varying proportions of chemical stabilizers and D-cracked aggregates were evaluated using the standard Proctor, unconfined compressive strength, linear shrinkage, and California Bearing Ratio tests. Microstructure characteristics of selected mixtures were explored using scanning electron microscopy (SEM) and energy dispersive X-ray tests. Laboratory test results indicated that RCA, in conjunction with all cementitious materials except lime, improved clay strength, stiffness, and shrinkage properties. SEM results indicated that RCA caused a low void space and a dense arrangement of soil particles. RCA effectively improved evaluated mixture properties when an adequate soil-RCA bond was reached using chemical agents. The long-term performance of full-depth flexible pavements with stabilized mixtures as subgrade was assessed in the AASHTOWare Pavement ME Design (commonly known as MEPDG) software. The life-cycle cost of flexible pavements with stabilized mixtures was estimated for a 40-year design period. Economic analysis results indicated that RCA was cost effective only if it was used with a combination of fly ash and Portland cement.

Download or read book Stabilization of Existing Subgrades to Improve Constructibility During Interstate Pavement Reconstruction written by Joakim G. Laguros and published by . 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.
