Effects of Warm-mix Asphalt Additives on Asphalt Mixture Characteristics and Pavement Performance

The primary objective of this research is to evaluate the feasibility of several WMA mixtures as potential asphalt paving mixtures for Nebraska pavements. To that end, three well-known WMA additives (i.e., Sasobit, Evotherm, and Advera synthetic zeolite) were evaluated. For a more realistic evaluation of the WMA approaches, trial pavement sections of the WMA mixtures and their HMA counterparts ...

Stone Mastic Asphalt Pavement Technology for the New Millennium

Since the 1960s, Stone Mastic Asphalt (SMA) pavement surfaces have been used successfully in Germany on heavily trafficked roads. Because of its excellent performance characteristics, road authorities in Germany as well as major European Countries quickly adopted SMA as a standard wearing course. As a consequence of an asphalt study tour in Europe of an American delegation in 1990, SMA test sec...

Investigation of Clay Balls in Asphalt Pavement

Clay ball is a pavement surface defect which refers to a clump in which clay or dirt is 8 mixed with hot asphalt mixture. Clay ball is typically caused by a combination of aggregate 9 contamination of clay or soil, high aggregate moisture, and low production temperature at the 10 asphalt plant. It usually appears a few weeks or months after paving under traffic load, after being 11 liquefied an...
