Abstract

The skid resistance of asphalt concrete is highly influenced by the microtexture and macrotexture of pavement surface. It is believed that the microtexture and macrotexture are affected by the surface texture of pavement, which refers to the arrangement of aggregates and their aggregates characteristics. The objective of this study is to evaluate the effects of aggregate properties and its orientation on microtexture and macrotexture by using an image analysis technique. Test results reveal that texture values obtained through the use of an image analysis technique is highly sensitive to changes in microtexture. The aggregate types and their related properties which are polished stone value, angularity, and texture of aggregate significantly affect the microtexture whereas the macrotexture is considerably influenced by fineness modulus, angularity and texture.
