More Information
Summary:The invention belongs to the technical field of road asphalt, provides a water damage resistant asphalt mixture and a preparation method thereof, and solves the problem of water damage to an asphalt pavement. The mixture comprises 14-16 parts of asphalt, 2-4 parts of cement, 5-8 parts of mineral powder, 6-9 parts of calcium hydroxide, 80-90 parts of stone and 8-12 parts of modified titanium dioxide. According to the invention, the mineral powder and the stone material with particle size grading can make the whole pavement more compact, and prevent the stone material from flying away; the cement and the calcium hydroxide can enable the asphalt and the stone to be tightly combined and prevent the asphalt from being peeled off from the surface of the stone. And the modified titanium dioxide quickly drains water through a hydrophobic effect to prevent water from accumulating in the road to form water pressure, so that the adhesion between the asphalt and the aggregate is reduced. Through cooperation of different
