Feb 28, 2018· Specifications for the polishing resistance of aggregate are only given for coarse aggregate. However, given the various mixture types as seen in Table 1 it is questionable if the fraction of fine aggregate (up to 55 M.-%) ought to be neglected. Asphalt surfacing mix with nominal coarse aggregate size from 6 mm to 20 mm was tested by W/S test carried by Woodward .

The Compacted Aggregate Resistance (CAR) test is a procedure used to analyze the quality of asphalt. It is a punch shear test that indirectly measures the shape and angularity of fine aggregates. The CAR test is in the developing process of replacing the current Superpave standard for …

Angularity of the fine aggregates was measured using Superpave fine aggregate angularity (FAA), direct shear test, compacted aggregate resistance (CAR), and VDG-40 videograder. Friction angle derived from direct shear tests and slenderness ratio from the …

The CAR test is basically a ''punch shear'' that measures the shear resistance of compacted fine aggregates which is an indirect measure of the shape and angularity of fine aggregates. Conceptually, the CAR test which is similar to the California Bearing Ratio test is in the developing process of replacing the current Superpave standard for FAA ...
