Abstract: Long-term draindown is the term adopted in this study to describe the downward flow of binder in a porous asphalt mixture due to the force of gravity at high temperatures experienced during service, especially in warmer ...

Abstract: The objective of this study was to evaluate the feasibility of using warm mix asphalt (WMA) technologies to produce quality open graded friction course (OGFC) mixtures. This evaluation was based on the comparison of Evotherm ...

Abstract: This research investigated the effect of aggregate gradation on the performance of porous asphalt mixtures. Ten aggregate gradations, which represent typical gradations used by 20 different United States highway agencies ...

Abstract: Porous asphalt mixtures have been used for more than 60 years, but it was not until 1974 that the first formalized procedure was created by the Federal Highway Administration to design mixtures for open-graded friction ...

Abstract: There have been many studies investigating the properties of crumb rubber modified (CRM) binders, but few that have attempted to quantify the specific effects that the addition of crumb rubber has on asphalt binders. The ...

Abstract: The recycling of hot-mix asphalt pavements containing a crumb rubber modifier (CRM) has been an area of interest since CRM was first used in asphalt paving materials over

Abstract: A laboratory investigation was carried out to study the effects of various compaction temperatures on moisture susceptibility and rutting resistance of warm-mix-asphalt (WMA) mixtures containing moist aggregates using a ...

Abstract: This research investigates the influence of aggregate gradation on the clogging characteristics of porous asphalt mixtures. Ten representative gradations used for open graded friction course (OGFC) applications from across ...

Abstract: This research seeks to address questions about the reduction in soil infiltration rates due to masking or embedding when a layer of open-graded aggregate is placed on top of soil. This is pertinent to the design and modeling ...
