Abstract

Skid resistance is one of the important parameters used in asphalt pavement characterization. Also, recently with wide extension in roads network over the world and high vehicles speed which lead to high record in accident rates. One of the accident causes is inadequate skid resistance. Various factors affect the skid resistance; some of these are material properties, vehicle speed, surface condition, pavement age, climate and contaminant type. Therefore, this study represents the effect of various contaminants on the skid resistance of asphalt pavement mixes. Two types of asphalt mixes were used; the first was fresh mix, while the second was reclaimed asphalt pavement (RAP) mix. The selected contaminants were water, lube oil and sand. Laboratory tests were performed for hot mix asphalt during (140 days for fresh and 75 days for Rap) and temperature variation range of (10-33)0C. British Pendulum (BP) Tester was used to identify the skid resistance values. The test was carried out of leveled flexible pavement slabs for both fresh and reclaimed mixes. Two sections for every slab were tested for both control and contaminated slab. The results indicated that British Pendulum Number (BPN) values changed by the change of contaminant type. Also, it was observed that the lowest values of BPN were investigated using lube oil compared to water and sand. Finally, Significant changes have been occurred in BPN values by the variation in mix type.
