Abstract: For designing pavements many state agencies, including those in Oklahoma, use the 1993 AASHTO Guide for Design of Pavement Structures, which is empirical in nature. However, the Mechanistic-Empirical Pavement Design Guide ...

Abstract: A laboratory study was undertaken to evaluate the influence of three cementitious additives on the indirect tensile and fatigue behavior of two subgrade soils. Hydrated lime (or lime), class C fly ash (CFA), and cement ...

Abstract: An improved two‐dimensional plane‐strain numerical procedure based on the incremental‐iterative nonlinear finite‐element method is developed to predict ground subsidence caused by underground mining. The procedure emphasizes ...

Abstract: In this paper, we present a simplified model for pavement drainage system. The model accounts for the accumulation and flow of water through a drainable base and edge drain representing a porous medium. There is an inflow ...

Abstract: A finite-element algorithm is developed to analyze the dynamic response of multiple, jointed concrete pavements to moving aircraft loads. In the finite-element idealization, the pavement-subgrade system is idealized by ...

Abstract: The study collected both design and performance data on 342 chip seal projects worth nearly $30 million that had been completed in the Texas Department of Transportation’s Atlanta District since 1996. One hundred sixty ...

Abstract: In this study, a four-layer feed-forward neural network is constructed and applied to determine a mapping associating mix design and testing factors of asphalt concrete samples with their performance in conductance to flow ...
