The paper analyzes the influence of different methods and conditions on the different indicators and excavates the internal correlation of different pavement skid resistance performance indexes, aiming to improve the effectiveness and accuracy of pavement skid resistance performance detection. Based on the test data of RIOHTrack full-scale track, this paper analyzes the decay law of pavement skid resistance performance, including the sideway force coefficient (SFC), British pendulum number (BPN), mean texture depth measured by sand patch method (MTD) and sensor measured texture depth by laser method (SMTD), under different equivalent single axle load times (ESALs).

The pavement skid resistance performance index is one of the most important indexes to ensure driving safety. 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. The tests were performed on wet surface conditions at a temperature ranging from 30 ☌ to 55 ☌ and varying penetration index in asphalt concrete mixtures.The skid resistance value decreased with increasing surface temperature. The addition of this substance reduces the penetration of asphalt at 25 ☌. Buton asphalt additive is made by refining bitumen rocks with low penetration.

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. 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. Skid resistance on pavement surfaces can affect the safety of road users and impact their travel efficiency.
