Asphalt mixture doped with basalt fibers of mixed lengths and preparation method of mixture
The invention belongs to the field of road engineering materials, and particularly relates to an asphalt mixture doped with basalt fibers of mixed lengths and a preparation method. The mixture is prepared from the following components: SBS modified asphalt accounting for 4.05%-4.45% of the weight of mineral aggregate, basalt fibers with a total doping amount being 0.273%-0.361% of the weight of the mixture, and the mineral aggregate accounting for 95.189%-96.677% of the weight of the mixture, wherein the mineral aggregate comprises coarse aggregate, fine aggregate and mineral powder, the coarse aggregate and the fine aggregate are made of basalt, and the basalt fibers are basalt fibers with mixed lengths. Basalt fibers are co-doped in the prepared asphalt mixture, so that the problem thatasphalt pavements are prone to cracking and other diseases is solved, and the asphalt mixture has great significance in improving the use quality of the pavements and prolonging the service life of the asphalt pavements, and is better in comprehensive performance and better in economic benefit.
本发明属于道路工程材料领域，具体涉及一种掺混合长度玄武岩纤维沥青混合料及制备方法。以质量百分比计，所述混合料包括如下组分组成：SBS改性沥青占矿料重量的比例4.05％～4.45％、玄武岩纤维总掺量占混合料比重的比例0.273～0.361％，矿料占混合料总重的比例95.189％～96.677％；所述矿料包括粗集料、细集料和矿粉，粗细集料材质为玄武岩所述玄武岩纤维为混合长度的玄武岩纤维。本发明在所制备沥青混合料中复掺玄武岩纤维，有利于解决沥青路面易产生裂缝等病害问题，对提高路面使用品质、延长沥青路面使用寿命具有较大意义，而且综合性能更好，经济效益较优。
