【 摘 要 】

In order to study the influencing factors on the shear strength of asphalt mortar with high viscosity, many different compositions are considered to analyse the shear strength of asphalt mortar, such as asphalt from different resource, mineral powder, wimble weight, temperature and ratio of filler to bitumen. The results indicate that among these factors, the influence of wimble strength is the smallest, which can be ignored. The shear strength of asphalt mortar decreases with increasing temperature from 25°C∼50°C. Meanwhile it changes with the ratio of filler to bitumen by 1.2 under the temperature changing from 25°C∼35°C. Also with the rising ratio between filler and bitumen, the sheer strength of mortar increases. However, the temperature sensitivity changes differently with its peak. Compared to the type of mineral powder, the influence of asphalt resource on shear strength and temperature sensitivity are more significant.
