Abstract: Saturation of voids in pavement layers and accumulation of water at the interface with an underlying layer may lead to moisture damage in asphalt pavements. Interconnected voids facilitate the flow of water through hot mix ...

Abstract: To predict the pavement response correctly at any condition, the constitutive relation between stress and strain will require the use of a damaged modulus. Several asphalt concrete slabs constructed in the laboratory using ...

Abstract: The quality of cold in-place recycling (CIR) is strongly dependent on the capability of proper laboratory investigation and design, and quality control during construction. The objective of this study was to evaluate the ...

Abstract: A recent survey by ASCE showed a major need for rebuilding the critical components of the nation’s aging infrastructure, such as roads and water-supply systems. To accomplish this major task, in addition to knowledge of ...

Abstract: The paper presents a framework to predict and consider the risks associated with the permeable layer in a pavement subsurface drainage system and suggests strategies to reduce the risks and improve the performance of the ...

Abstract: Dynamic fragmentation of hot mix asphalt (HMA) under high strain rate loading can be expected under various situations, such as milling, earthquakes, or explosions. This paper reports on an empirical study that was conducted ...

Abstract: An increase in the number of extreme weather events and gradual shifts in climate parameters due to a changing climate pose a serious threat to the nation’s roadway infrastructure. A systematic approach is needed to define ...

Abstract: The objectives of this study were to determine a suitable set of tests to use with a moisture-conditioning process and to develop a machine learning model to predict the moisture susceptibility of hot mix asphalt. ...
