Stone Mastic Asphalt An Overview | Sciencedirect Topics
10.3.2.6 stone mastic (matrix) asphalt. sma is a relatively thin (12.5–40 mm) gapgraded, densely compacted, hma that is used as a surface course on both new construction and surface renewal. it is a mixture of asphalt cement, coarse aggregate, crushed sand, and additives.

Abstract to quantitatively analyze and study the water stability of crushed gravel asphalt mixture by using surface energy theory, the surface energy parameters of crushed gravel samples at 20℃ are tested by using the gas sorption method, and the surface energy parameters of four antistripping agent asphalts with different dosages (0, 0.2, 0.4, 0.6) at 20℃ are tested by using the.
