Document Type and Number:
WIPO Patent Application WO/2020/199781
Kind Code:
A1
Abstract:
Disclosed is a method for paving a combined base course asphalt road surface. A base course structure and an asphalt surface course are successively paved onto a soil subgrade (1) from bottom to top, wherein the base course structure is composed of an asphalt mixture viscoelastic anti-fatigue cushion (3), a lower semi-rigid base course (4) and an upper base course (5), which are paved onto the soil subgrade (1) from bottom to top. According to the method, damage to the lower semi-rigid base course (4) caused by cavities in the subgrade and uneven stress can be reduced, the anti-fatigue performance of the lower semi-rigid base course (4) and a reflection crack resistance capability of a road surface structure can be improved, the service life of the road surface structure can be prolonged, and the thickness of the lower semi-rigid base course (4) can be reduced, and the consumption of cement, sand and gravel, etc. can also be reduced.
