The abrasion Test measures aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in Los Angeles Machine. The aggregates are used for the surface course of the …
The aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed …
A Superpave mix with a 12.5-mm (1/2-in.) nominal maximum aggregate size gradation was produced with each aggregate source using the same PG 64-22 asphalt binder. The mixtures were produced to investigate the impact of aggregate properties on their volumetric properties as well as the tensile strength from the indirect tension tests and …
