Abstract: Field and laboratory testing programs were conducted to develop an efficient methodology for estimating resilient modulus

Abstract: A key requirement for performance-based specification for pavement materials is the selection of laboratory tests that can predict their response under conditions similar to those encountered in the field. This paper ...

Abstract: This paper summarizes the results of a research study that was conducted to evaluate the effects of asphalt binder and aggregate gradation on the rutting and cracking resistance of asphalt mixtures used in construction of ...

Abstract: This study aims at characterizing the nanostructure and microstructure and the mechanical behavior of asphalt clay nanocomposites. To this end, various atomic force microscopy (AFM) techniques (i.e., tapping mode imaging, ...

Abstract: In this paper, various nanomechanical and macromechanical techniques were used to study the effect of a reclaimed asphalt pavement (RAP) binder on the microstructure and properties of a virgin asphalt binder and to evaluate ...

Abstract: In this paper, various Atomic Force Microscopy (AFM) techniques are utilized to study the effects of different warm mix asphalt (WMA) additives on the nanostructure and microstructure as well as the adhesive and cohesive ...

Abstract: Warm mix asphalt (WMA) has received considerable attention in the past few years to reduce energy consumption and pollutant emissions during hot mix asphalt (HMA) production and placement. However, many concerns and questions ...

Abstract: A finite-element model was developed using ABAQUS software package to investigate the effect of placing geosynthetic reinforcement within the base course layer on the response of a flexible pavement structure. A critical ...

Abstract: The main objective of this study was to perform survival life analysis and life-cycle cost analysis of different patching methods and materials commonly used for winter pothole maintenance. To this end, a comprehensive ...

Abstract: This paper summarizes the results of a study that was conducted to evaluate the performance of field-produced aramid fiber-reinforced asphalt mixtures used for resurfacing applications and compare it to that of polymer-modified ...
