Abstract: Longitudinal joint cracking is one of the most prevalent forms of distress in asphalt concrete pavements. The joint area does not achieve the same density as the mat due to an unconfined edge on the initial pass and a cold ...

Abstract: The changes in the stiffness of two asphalt concrete mixtures due to temperature, fatigue damage growth, and healing during rest periods are evaluated using the impact resonance method. The impact resonance method is a ...

Abstract: Thermal cracking performance assessment of flexible pavements is paramount to improve the quality of the roads in cold-climate regions. In this paper, a reduced testing framework for analysis of hot-mix asphalt (HMA) ...

Abstract: A fatigue performance prediction model of asphalt concrete is developed from a uniaxial constitutive model based on the elastic-viscoelastic correspondence principle and continuum damage mechanics through mathematical ...

Abstract: This paper addresses issues of machine compliance and instrumentation that affect the measurement of asphalt concrete material properties in the laboratory. Accurate determination of fundamental material properties is ...

Abstract: The increasing cost of virgin asphalt and aggregate has increased the interest in using higher percentages of recycled asphalt pavement (RAP) in hot mix asphalt (HMA) mixtures. The purpose of this research project was to ...

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 ...
