Assumption of a linear elastic system under static loading is questionable for structural response analysis of pavement-subgrade systems under dynamic nondestructive testing and moving wheel loads, especially if a deteriorated pavement is under study. Presented are the results of a parametric study using the three-dimensional finite element ABAQUS code; it investigates the effects of pavement d...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

This article presents the effect of taking into account subgrade coefficient on static work a pontoon with an internal partition, made in one stage and treated computationally as monolithic closed rectangular tank. An exemplary is single, ready-made shipping element that can be used float for building. By assembling several floats together, structure form floating platform. Due to increasingly ...

The bearing plates used in plate load test for highway engineering are typically rigid. However, due to limitations obtaining the accurate distribution of compressive stress at bottom plate, there is often a significant deviation between measured subgrade resilient modulus and actual condition. To address this issue, flexible can be obtain more modulus. In study, we use variance degree mean qua...

Rubblization is one of the surface preparation techniques before placing a Hot Mix Asphalt (HMA) overlay that involves breaking the Portland Cement Concrete (PCC) pavement into pieces. This paper describes the structural assessment related to the long term performance of rubblized concrete pavements in Iowa. The structural performance of seven representative in-service rubblized concrete paveme...
