Abstract

Skid resistance on pavement surfaces can affect the safety of road users and impact their travel efficiency. This value specifies the frictional forces on the wheels of vehicles that will avoid the occurrence of slip in wet or dry conditions. This study tested skid resistance using tools a Skid Resistance Tester and a British Pendulum Tester. Analyses were performed to evaluate the surface roughness of an asphalt concrete wearing course (AC-WC) with bitumen 60/70 and a Buton asphalt additive blend with the same aggregate composition. Buton asphalt additive is made by refining bitumen rocks with low penetration. The addition of this substance reduces the penetration of asphalt at 25 °C. The tests were performed on wet surface conditions at a temperature ranging from 30 °C to 55 °C and varying penetration index in asphalt concrete mixtures. The skid resistance value decreased with increasing surface temperature. The additive caused a change in the asphalt penetration index in asphalt concrete, resulting in a higher skid resistance value than that of virgin bitumen 60/70.
