Abstract: This study was undertaken to identify test procedures capable of reliably assessing concrete aggregate freeze-thaw durability and establish appropriate acceptance criteria for the same. Highway condition surveys were ...

Abstract: Pavement temperature profile data can be quite useful in the analysis of stresses in jointed concrete pavements produced by temperature gradients within the slabs. Many stress analysis procedures consider the temperature ...

Abstract: This study investigated the use and suitability of the International Roughness Index (IRI) for predicting vertical acceleration in truck shipments at recommended highway speeds. The investigation resulted in the development ...

Abstract: A component dowel-bar model has been developed to simulate the doweled joint in portland-cement-concrete (PCC) pavements. The model consists of two bending beams of finite length, embedded in concrete, connected by a ...

Abstract: This paper reports new findings in the spectral analysis of pavement roughness. Elevation profiles of federal and interstate highways were measured with a profilometer, and spectral analysis was used to compute power ...
