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.
