Water-damage-resistant asphalt mixture and preparation method thereof
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 materials, the water damage resistance of the asphalt mixture is improved, and the service life of a road is prolonged.
本发明属于道路沥青技术领域，提供了一种抗水损沥青混合料及其制备方法，解决了沥青路面水损害的问题。该混合料包含沥青14～16份、水泥2～4份、矿粉5～8份、氢氧化钙6～9份、石料80～90份、改性二氧化钛8～12份。在本发明中，粒径级配的矿粉和石料可以使整体路面更加密实，防止石料的飞散；水泥和氢氧化钙可以使沥青和石料之间紧密结合，防止沥青从石料表面进行剥落。改性二氧化钛通过疏水作用快速排水，防止水分积聚在道路内部形成水压力，从而降低沥青和骨料间的粘附性。本发明通过不同材料的配合，提升了沥青混合料的抗水损性，延长了道路的使用寿命。
