• Abstract:
  This paper describes the results of a laboratory study conducted to evaluate the influence of Aspha-min® and Sasobit® ; additives on the behaviour of warm asphalt mixtures. Specimens were compacted at two temperatures, 100 and 1458C, and ; were subjected to two different testing procedures. The one-third model mobile traffic simulator and the thermal stress ; restrained specimen test were chosen to assess the susceptibility to moisture and thermal cracking. Results showed that ; warm asphalt mixtures prepared with Sasobit may be more susceptible to moisture damage, and both additives may ; negatively impact the low-temperature cracking performance compared with the control mixture.
