Abstract

Damage or failure often occurs in the Asphalt Concrete – Wearing Course (AC-WC) pavement layer. This is indicated by the damage that appears in the form of grain release and surface defects in the form of holes to cracks due to fatigue. The amount of road damages indicates that silica sand needs to be used in place of fine aggregate in order to improve the quality of the road pavement. Silica sand substitution is expected to increase the durability of the road pavement. Based on the IRS, IDF, and IDS values obtained by each mixture, the substituted mixture without silica (0%) showed the smallest average loss of immersion strength compared to the other mixtures. But, even though the IRS has decreased, silica sand can still be used because the IRS value still meets the specifications, namely at least 90%.
