Abstract:
This paper studied the permeability performance of the different waterproof film coating based on the Darcy theory with variable head testing methods by using SL4 permeability machine. Authors firstly discussed the different external environments effected on antipermeability of paving composite structure for asphalt concrete bridge deck. The results show that fiber added in concrete can improve antipermeability performance of concrete；antipermeability of SBS modified asphalt waterproof film is best; if fiber concrete smooth layer and SBS modified asphalt waterproof film are used in salty areas, the waterproof effect is good; salt corrosion and thawing environment both can reduce antipermeability of paving composite structure for asphalt concrete bridge deck and thawing environment has much more influence on it. 6 tabs, 1 fig, 10 refs.
