Book Synopsis Fly Ash Soil Stabilization for Non-uniform Subgrade Soils by : David J. White (Ph. D.)
Download or read book Fly Ash Soil Stabilization for Non-uniform Subgrade Soils written by David J. White (Ph. D.) and published by . This book was released on 2005 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: To provide insight into subgrade non-uniformity and its effects on pavement performance, this study investigated the influence of non-uniform subgrade support on pavement responses (stress and deflection) that affect pavement performance. Several reconstructed PCC pavement projects in Iowa were studied to document and evaluate the influence of subgrade/subbase non-uniformity on pavement performance. In situ field tests were performed at 12 sites to determine the subgrade/subbase engineering properties and develop a database of engineering parameter values for statistical and numerical analysis. Results of stiffness, moisture and density, strength, and soil classification were used to determine the spatial variability of a given property. Natural subgrade soils, fly ash-stabilized subgrade, reclaimed hydrated fly ash subbase, and granular subbase were studied. The influence of the spatial variability of subgrade/subbase on pavement performance was then evaluated by modeling the elastic properties of the pavement and subgrade using the ISLAB2000 finite element analysis program. A major conclusion from this study is that non-uniform subgrade/subbase stiffness increases localized deflections and causes principal stress concentrations in the pavement, which can lead to fatigue cracking and other types of pavement distresses. Field data show that hydrated fly ash, self-cementing fly ash-stabilized subgrade, and granular subbases exhibit lower variability than natural subgrade soils. Pavement life should be increased through the use of more uniform subgrade support. Subgrade/subbase construction in the future should consider uniformity as a key to long-term pavement performance.

This book was released on 2005 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil treated with self-cementing fly ash is increasingly being used in Iowa to stabilize pavement subgrades, but without a complete understanding of the short- and long-term behavior. To develop a broader understanding of fly ash engineering properties, mixtures of five different soil types, ranging from ML to CH, and several different fly ash sources (including hydrated and conditioned fly ashes) were evaluated.

Book Synopsis Load-Deflection Behavior of Lime-Stabilized Layers by : L. P. Suddath
Download or read book Load-Deflection Behavior of Lime-Stabilized Layers written by L. P. Suddath and published by . This book was released on 1975 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The static and dynamic load-deflection response of soil-lime pavement layers was investigated. Soil-lime mixture layers 6, 9, and 12 in. thick were compacted over a stiff subgrade (k=450 psi/in.) and a soft subgrade (k=50 psi/in.). The soil-lime layers were statically and dynamically loaded after curing periods of 2, 14, 28, and 56 days. Supplemental subgrade soil and soil-lime mixture property data were also developed. The load-deflection data are summarized and analyzed. Various pavement behavior theories are evaluated to determine their capability to predict the load-deflection behavior of soil-lime pavement layers.

Book Synopsis Use of Soil-Steel Slag-Class-C Fly Ash Mixtures in Subgrade Applications by : Irem Zeynep Yildirim
Download or read book Use of Soil-Steel Slag-Class-C Fly Ash Mixtures in Subgrade Applications written by Irem Zeynep Yildirim and published by Joint Transportation Research Program. This book was released on 2013-10 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Indiana, the steelmaking industries and power plants generate large quantities of steel slag, blast furnace slag and fly ash every year. The excess of these underutilized industrial by-products are stockpiled and eventually landfilled at disposal sites. Use of steel slag, fly ash and blast furnace slag in road applications, such as in subgrade stabilization projects, can be a cost-effective alternative to lime stabilization in some cases. In addition, use of large quantities of these underutilized industrial by-products in these types of applications helps to reduce the need for new disposal sites and to conserve natural resources. The main objectives of this research were to evaluate the feasibility of using soil-steel slag-Class-C fly ash and soil-steel slag-blast furnace slag mixtures in subgrade applications and to implement the selected mixture as a subgrade material in a road construction project of INDOT. In order to achieve these goals, in situ clayey soils, collected from a prospective implementation site, were characterized through a series of laboratory tests which included specific gravity, grain size distribution, Atterberg limits, compaction and unconfined compressive strength. Two types of steel slag mixtures were evaluated for use in subgrade stabilization applications: i) steel slag-Class-C fly ash mixtures and ii) steel slag-blast furnace slag mixtures. The mechanical properties of soil-5% steel slag-5% Class-C fly ash, soil-7% steel slag-3% Class-C fly ash, soil-8% steel slag-2% Class-C fly ash, and soil-7% steel slag-3% blast furnace slag mixtures were determined through compaction and unconfined compression tests. CBR swelling tests were also performed to assess the swelling potential of the mixtures. The optimum moisture content and maximum dry unit weight of the in situ clayey soil samples were 13% and 18.56 kN/m3 (118.2 pcf), respectively. Based on the results of the long-term CBR swelling tests, the maximum swelling strain of the compacted soil samples was approximately 0.41 %. The average unconfined compressive strength of the in situ soil samples was 282.9 kPa (41 psi). Unconfined compressive strength tests performed on various mixtures at different times indicated the occurrence of stronger cementitious reactions in the soil-steel slag-Class-C fly ash mixtures than in the soil-steel slag-blast furnace slag mixtures. The two-day and seven-day unconfined compressive strength of the compacted soil-7% steel slag-3% Class-C fly ash mixture were 820 kPa (119 psi) and 886 kPa (128 psi), respectively. The maximum 1-D swelling strain of the soil-7% steel slag-3% Class-C fly ash mixture was 0.13 %. The soil-7% steel slag-3% Class-C fly ash mixture was selected as the most suitable and cost-effective subgrade material for the implementation project. The implementation project for the soil-steel slag-Class-C fly ash mixture was located at the intersection of 109th Avenue and I-65, near Crown Point, Indiana. The pre-mixed 7% steel slag-3% Class-C fly ash mixture was used to stabilize the in situ subgrade soils of some sections of the I-65 ramps located in the SW and NW quadrants of the intersection of 109th Avenue and I-65. Field compaction quality control was done by performing DCPTs and nuclear gauge tests. Cracks or signs of distress were not observed on the subgrade before base course and concrete placement. The soil-steel slag-Class-C fly ash stabilized subgrade performed satisfactorily.
