Wear-resistant and skid-resistant asphalt pavement material and production process thereof
According to the wear-resistant and skid-resistant asphalt pavement material and the production process thereof, the modified graphene oxide, the modified diatomite and the modifier are mixed with the asphalt macadam, so that the skid resistance and wear resistance of a pavement can be improved, potential safety hazards of driving are reduced, the wear-resistant and skid-resistant asphalt pavement material has relatively good compressive strength, the service life of the pavement can be prolonged, and the service life of the pavement is prolonged. The anti-scouring performance of the asphalt pavement material can be remarkably improved by adopting the monodisperse nano alpha aluminum oxide, and the modified graphene can provide a large number of active sites and fully react with asphaltene components to form stable chemical bonds, so that the formed layered structure is more compact, and the anti-scouring performance of the asphalt pavement material is improved. The compact layered structure can effectively prevent volatilization of light components in the asphalt, prevent invasion of partial oxygen and moisture, prevent further oxidation of an internal mixture and prevent water molecules from being difficultly adsorbed on the surfaces of asphalt particles, so that the influence of aging on low-temperature crack resistance and water damage resistance of the asphalt mixture is slowed down.
本申请提供的一种耐磨抗滑沥青路面材料及其生产工艺，通过采用改性氧化石墨烯、改性硅藻土以及改性剂与沥青碎石混合，能够提高路面的防滑性能和耐磨性，减少行车的安全隐患，并且具有较佳的抗压强度，能够延长路面的使用寿命，通过采用单分散纳米α氧化铝可显著提高沥青路面材料的抗冲刷性能，改性石墨烯可以提供大量的活性位点，与沥青质的组分充分反应形成稳定的化学键，这使形成的层状结构更加致密，这层致密的层状结构既可有效防止沥青中轻组分的挥发，也能防止部分氧气和水分的侵入，阻止内部混合料被进一步氧化，水分子难以吸附在沥青颗粒表面，从而减缓老化对沥青混合料低温抗裂及抗水损害性能的影响。
