Abstract: This paper describes a research study that was conducted to evaluate the design parameters for asphalt pavements and the mechanical properties of cold mix asphalt concrete (CMA) with petroleum-contaminated soils (PCSs). ...

Abstract: Infrastructure systems in the United States are in need of urgent maintenance and rehabilitations. Preservation of culvert networks, a major component of U.S. infrastructure systems, at an acceptable level of serviceability ...

Abstract: The low-viscosity stabilizer, colloidal silica (CS), is extensively used as a grouting material in the construction of grout curtains to prevent fluid movements. It is a low viscosity and nontoxic material, which is suitable ...

Abstract: A reliable pavement performance prediction model is needed for road infrastructure asset management systems or pavement management systems. In this study, the data on roughness progression of asphalt pavements in the ...

Abstract: A model based on the discrete element method (DEM), ASBAL, was developed by modifying the TRUBAL program to simulate hot mix asphalt (HMA). To represent asphalt cement, several viscoelastic elements (i.e., Maxwell, ...

Abstract: This paper summarizes the characteristics of chromite ore processing residue (COPR) in terms of their chemical compositions, phases, and recycling potential of iron and chromium through preliminary magnetic separation. ...

Abstract: This paper describes the test results of a demonstration study on the use of vitrified soils as highway construction aggregates. It is based on a bench- and pilot-scale feasibility study of the remediation of chromium-contaminated ...

Abstract: Air sparging is an emerging soil remediation method to decontaminate saturated granular soils and groundwater with volatile organic compounds (VOCs). The efficiency of an in situ sparging system is controlled by the extent ...

Abstract: An acoustic emission (AE) method was used to detect leaks and discern their location under flow conditions in a 304.8-m-long, 305-mm-diameter buried steel pipeline at the New Jersey Institute of Technology/U.S. Environmental ...
