| Abstract | The skid resistance is an indicator of paveme nt surface to ensure safety for the vehicles traveling on the pavements. The skid resistan ce 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 objectives of this study aim to identify and evaluate the effect of factors affecting skid resistance on asphalt pavement surfaces. The skid resistance and m acrotexture of mixes are measured by using the British Pendulum Tester and sand patch test method, and microtexture regarding aggregate characteristics and its orientation m easured by an image analysis technique. The results showed that the properties of aggr egate and gradation of mixes are significant factors affecting skid resistance and macrotexture. The macrotexture increases as the binder content, bulk density, and the percen t passing of sieve #4.75 decreases. The skid resistance increases as the binder content a nd fineness modulus decreases, and polishing stone value increases. Moreover, contaminant water from fish mucus can affect skid resistance for dense-graded asphalt mixture. In order to evaluate the effects of aggregate properties and its orientation on microtexture and macrotexture, 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 textur e of aggregate significantly affect the microtexture whereas the macrotexture is considerably influenced by fineness modulus, angularity and texture. Consequently, the empi rical model developed in this study can be used to predict macrotexture in asphalt pavement surfaces. |
