Abstract: Because of the large grainsizes typical of railroad ballast, large triaxial samples are required to assess the reactions of these materials. The parallel gradation modeling technique was originally developed by John Lowe ...

Abstract: In recent years, enzyme-induced carbonate precipitation (EICP) has emerged as a bioinspired and innovative technique that has captured the attention of geotechnical engineers specializing in soil stabilization. This method ...

Abstract: Soil compaction quality control plays an important role in earthwork construction. Compacted dry density is only loosely related to the actual deformation of the compacted soil. Rather than using dry density as the controlling ...

Abstract: Thermal conductivity measurement is a quick and easy test for compacted soils. This study presents the results of thermal conductivity testing on silt compacted under standard and modified Proctor efforts. A comparison of ...

Abstract: A survey of current literature has revealed that the testing protocol for determining the time of setting of fly ash–soil mixtures is not available. Although the current ASTM standard recommends using the Vicat needle ...

Abstract: Finite-element analysis on a pavement structure under traffic loads has been a viable option for researchers and designers in highway pavement design and analysis. Most of the constitutive drivers used were nonlinear elastic ...

Abstract: Soft clays are widely distributed in Missouri, United States. Due to their relatively low strength and high compressibility, subgrade construction in soft clays has encountered many difficulties. In recent practice, the ...

Abstract: Strain-controlled cyclic simple-shear tests were performed on silica sand with radial strain measurements. The specimens were tested under a constant
