    Abstract
  • In order to analyze the influence of mineral power on asphalt mortar viscosity, Brookfield viscometer was used to test the viscosities of asphalt mortars with different filler types and filler bitumen ratios, and the influencing factors were studied.Test result shows that there is 4.7 times gap among the viscosities of different mortars, and the gap is bigger with the increase of filler bitumen ratio; adding mineral power can reduce the temperature sensitivity of the mortar, but which is affected by mineral power type and dosage; the difference of construction temperatures among different asphalt mortars can reach about 30 ℃.So it is necessary to filtrate the mineral power type according to mineral power character for reducing the bad effect on asphalt mixture performance, and modify the determination method of active mixture construction temperature for considering the function of mineral power.
