Novel asphalt mixture for roads
The invention relates to the technical field of road engineering, and aims to provide a novel asphalt mixture for roads. Comprising SBS modified asphalt or 70 # A-grade common heavy traffic asphalt, aggregate composed of coarse aggregate, medium aggregate and fine aggregate in a ratio of (36-40): (30-36): (14-21), alkaline stone with the water content not larger than 1%, wood fiber with the mixing amount being 0-0.3% of the mass of the asphalt mixture, mineral fiber with the mixing amount being 0-0.4% of the mass of the asphalt mixture and an anti-rut agent with the mixing amount being 0-0.25% of the mass of the asphalt mixture. The mixing amount of the anti-stripping agent is 0-0.4% of the mass of the asphalt mixture. The method has the beneficial effects that the dynamic stability of the asphalt mixture can be remarkably improved, and the method has important effects of improving the usability of a pavement, prolonging the service life of the pavement and reducing the maintenance cost of the pavement, and is convenient to popularize and apply.
本发明涉及道路工程技术领域,其目的在于提供了一种道路用新型沥青混合料,包括SBS改性沥青或70#A级普通重交沥青、由比例为36~40:30~36:14~21的粗集料、中集料和细集料组成的集料、含水量不大于1%的碱性石料、掺量为沥青混合料质量0~0.3%的木质纤维、掺量为沥青混合料质量0~0.4%的矿物纤维、掺量为沥青混合料质量0~0.25%的抗车辙剂、掺量为沥青混合料质量0~0.4%的抗剥落剂。其有益效果在于:本发明能够显著提高沥青混合料的动稳定度,具有提高路面的使用性能,延长路面使用寿命,降低路面养护费用的重要作用,便于推广应用。
