Asphalt anti-skid wearing layer mixture and application thereof
The invention discloses an asphalt anti-skid wearing layer mixture and application thereof, and belongs to the field of road engineering. The mixture comprises high-low polishing value mixed coarse aggregate, fine aggregate, rubber asphalt and fiber, wherein the high-low polishing value mixed coarse aggregate is composed of high-polishing value coarse aggregate and low-polishing value coarse aggregate, the polishing value of the high-polishing value coarse aggregate is 46-56,the high-polishing value coarse aggregateaccounts for 22-92% of the total mass of the high-low polishing value mixed coarse aggregate, the polishing value of the low-polishing value coarse aggregate is 32-42, the low-polishing value coarse aggregate accounts for 8-78% of the total mass of the high-low polishing value mixed coarse aggregate, and the polishing value of the mixed coarse aggregate is not less than 45. Compared with the prior art, the mixture disclosed by the invention can greatly improve the anti-skid performance of the pavement while doping a large amount of low-polishing-value aggregate, and can be widely applied to pavement maintenance engineering of highways at the heavy traffic load grade and various grades below the heavy traffic load grade.
本发明公开了一种沥青抗滑磨耗层混合料及其应用，属于道路工程领域。所述混合料包括高低磨光值混合粗集料、细集料、橡胶沥青和纤维，所述高低磨光值混合粗集料由高磨光值粗集料和低磨光值粗集料组成，其中高磨光值粗集料的磨光值为46～56，占高低磨光值混合粗集料总质量的22～92％，低磨光值粗集料的磨光值为32～42，占高低磨光值混合粗集料总质量的8～78％，混合粗集料的磨光值不小于45。与现有技术相比，本发明混合料在大量掺加低磨光值集料的同时，可大幅提升路面抗滑性能，可广泛应用于重交通荷载等级及以下各等级公路的路面养护工程。
