Abstract
The research was performed to evaluate the cracking resistance characteristics of cold-mixed reclaimed asphalt pavement (RAP) using indirect tensile strength test and fatigue tests. Indirect tensile tests were conducted to estimate the indirect tensile strength at variable temperatures($10^{\circ}C\;and\;20^{\circ}C$). Fatigue tests were also carried out using 500kgf, 400kgf, and 300kgf of dynamic loads, and the fatigue life (Nf) for each mixture was measured. Indirect tensile strength of cold-mixed reclaimed asphalt pavement was about 90% of conventional 13mm dense-graded asphalt mixture. Fatigue life of cold-mixed reclaimed asphalt mixture was 70%, 55%, 30% (for 500kgf, 400kgf, 300kgf of load level, respectively) of the conventional one.
