Waste asphalt recycling method, pavement base material and construction method
The invention relates to the technical field of waste asphalt mixture recycling, and provides a waste asphalt recycling method, a pavement base material and a construction method.The waste asphalt recycling method comprises the following steps that screening is conducted, specifically, a waste asphalt mixture is sampled and screened to obtain the grading condition and the asphalt content of the waste asphalt mixture; mixing: mixing the waste asphalt mixture with gravel and cement according to the grading condition of the waste asphalt mixture to obtain a pavement base material; therefore, the waste asphalt mixture can be recycled to the maximum extent under the condition of reasonable technical economy, the construction cost is reduced, resources are saved, the water-stable mixture can be endowed with certain toughness, the problems that a cement stabilized macadam base material is large in shrinkage deformation, prone to cracking and the like are solved, the freezing resistance of a cement stabilized macadam base is improved, and the service life of the cement stabilized macadam base is prolonged. Loads are effectively dispersed, strain energy is dissipated, the pavement performance of the semi-rigid base asphalt pavement is improved, the service life is prolonged, and remarkable social and economic benefits are achieved.
本发明涉及废旧沥青混合料循环利用的技术领域，提供一种废旧沥青循环利用方法、路面基层材料及施工方法，废旧沥青循环利用方法包括以下步骤：筛分，对废旧沥青混合料进行取样筛分，以获得废旧沥青混合料的级配情况和沥青含量；混合，根据废旧沥青混合料的级配情况，与碎石和水泥进行混合，得到路面基层材料；如此，既可以在技术经济性合理的条件下最大限度地循环利用废旧沥青混料，降低工程造价，节约资源，还可以赋予水稳混合料一定的韧性，缓解水泥稳定碎石基层材料收缩变形大、易开裂等问题，提高水泥稳定碎石基层的抗冻性，有效地分散荷载、消散应变能，提升半刚性基层沥青路面的路用性能，延长使用寿命，具有显著的社会经济效益。
