Through working out an indoor plan of oil corrosion, the immersion Marshall tests and the freeze-thaw split tests were carried out to analyze the influence laws of oil corrosion on water stability for TLA modified asphalt mixture AC-13C. The results show that the influences of oil corrosion on water stability are closely related to the TLA mixing amount and the oil corrosion time. With the increase of TLA mixing amount, the change correlation between the immersion residual stability or the freeze-thaw residual strength ratio of oil corrosion and TLA mixing amount presents a single peak correlation from increase to decrease, and the peak value appears when the TLA mixing amount is about 30%. Meanwhile, the decreasing range of immersion residual stability of oil corrosion within the early 60minaccounts for above 80% of the total decreasing range. Therefore, the suitable TLA mixing amount and timely treatment of clearing oil pollution can effectively improve the anti-waterdamage ability of oil corrosion for TLA modified asphalt pavement.
