Effect of the filler particle size on the low and high temperature performance in asphalt mastic and concrete

Restrained cooling, time-to-failure and triaxial tests were conducted on mastics and dense and gap-graded asphalt mixtures prepared with two different fillers (coarse and fine fillers). Little variation in thermal stress response or time to failure was observed between samples with different gradations in mastic and mixture restrained cooling tests. Failure stresses and temperatures were identical for different mastics and mixtures, despite the …
