Abstract

According to the early disease of bridge deck pavement caused by waterproof-binding course, pavement performance of commen waterproof-binding course was was studied. First, determining the optimum spraying volume of modified asphalt under different treatments of leveling course through the pavement multi-function shear apparatus and laboratory pull-out test instrument, and the three kinds of surface treatment methods aer picking treatment,notch groove treatment and galling treatment, among which the optimum spraying volume of modified asphalt of picking and notch groove treatments are 1.4-1.6 kg/m2, and the galling treatment is 1.6-1.8 kg/m2. Through analyzing the test results, the shear strength and and bond strength of galling treatment is much higher than the shear strength of picking and notch groove treatments; Temperature and water are inportant factors of shear strength and bond strength of waterproof-binding course, and with the temperature increasing, the shear strength and bond strength reduced significantly; On the other hand, the results proved that ensuring waterproofness of bridge deck pavement is very important.
