The effects of initial conditioning and ambient temperatures on abrasion loss and temperature change of porous asphalt

This paper investigates the effects of initial conditioning and ambient temperatures on abrasion loss and temperature change of porous asphalt after subjected to 300 rotations in the Los Angeles drum. Identical specimens were tested at Universiti Sains Malaysia (USM) and Delft University of Technology (TU Delft), the Netherlands. Specimen temperature change decreased as the initial conditioning temperature increased. Temperature inside the drum remained unchanged. The abrasion loss of samples tested at TU Delft were higher than those tested at USM. Therefore for meaningful comparison of test results worldwide, the ambient temperature at which a Cantabro test is performed must be specified.
