Abstract: This paper presents the development of new methods for measuring aggregate resistance to polishing, and degradation. These are important properties that influence pavement skid resistance and resistance to distresses under ...

Abstract: Increased loads on hot-mix asphalt (HMA) pavements have necessitated the development of new-generation asphalt mixture designs that rely on stone-on-stone contact among coarse aggregates in resisting and distributing applied ...

Abstract: Aggregates are the most widely used construction materials in the world in structures built from both asphaltic and portland cement concrete composites. The performance of these composites is affected by aggregate shape ...

Abstract: This paper investigates the fresh, mechanical, and durability characteristics of self-consolidating concrete incorporating recycled asphalt pavements (SCCRAP). A total of 12 concrete mixtures were prepared and tested. ...

Abstract: Traffic loading is one of the key factors considered in pavement design. It is anticipated that the use of axle load spectra provides more accurate traffic-loading inputs than the traditional equivalent single-axle load ...

Abstract: Asphalt emulsions and cutbacks are mainly used for surface preservation treatments and as bonding layer during pavement construction. Cutback and emulsion residues are routinely evaluated to ensure specification compliance ...

Abstract: Stone-on-stone contact of the coarse-aggregate fraction is one of the main characteristics of permeable friction course (PFC) asphalt mixtures that is required to provide adequate resistance to both raveling and permanent ...

Abstract: Since the perpetual pavement (PP) concept was introduced, many countries and states, including Texas, have constructed PP roadways. To date, 10 PP sections in Texas have been in service since 2003. With the oldest section ...
