Effect of volume index of ETA-10 asphalt mixture on anti-slip performance of asphalt pavement
In order to study the anti-slip performance and influencing factors of ETA-10 asphalt mixture(ETA refers to Em-bedding thin asphalt mixture),four types of asphalt mixture and three different oil-stone ratios ETA-10 asphalt mixture were pol-ished by BPS plate grinder,the anti-skid performance of asphalt mixture was evaluated by attenuation rate,and the grey correlation between different volume indexes and anti-skid performance of ETA-10 was calculated by Matlab software.The results show that the anti-slip performance of ETA-10 asphalt mixture is excellent,and the pendulum attenuation rate is reduced by 0.2 percentage points when the high viscosity content is 0.29%,which enhances the anti-skid performance of ETA-10.The anti-skid properties of ETA-10 asphalt mixture with oil-stone ratio of 5.5%and 6.0%were similar,and the anti-skid properties of both were better than those of oil-stone ratio 5.0%.The influence of the volume index on the anti-slip sway value of ETA-10 asphalt mixture was as follows:VMA>VFA>VV.
