Anti-slip anti-crack secondary hot in-place recycling asphalt mixture and preparation method thereof
The invention discloses an anti-skid anti-crack secondary hot in-place recycling asphalt mixture and a preparation method thereof.The mixture is formed by mixing a waste asphalt mixture obtained after primary regeneration, a new asphalt mixture, a regenerant, strengthening and toughening fibers and other materials, and the mixture has excellent anti-skid durability and anti-crack performance; and after 50 thousand times of abrasion, the anti-sliding swing value BPN is greater than 52, and the fracture energy based on a semicircular bending-tensile experiment is greater than 3000J/m < 2 >. Compared with other secondary hot recycled asphalt mixtures, the secondary recycled material prepared by the invention has the advantages that the skid resistance and crack resistance are greatly improved, the service quality and the service life of a secondary hot in-place recycling asphalt pavement can be prolonged, and the secondary hot in-place recycling asphalt mixture has the outstanding advantages of energy conservation, environmental protection and the like.
本发明公开了一种防滑抗裂型二次就地热再生沥青混合料及其制备方法，该混合料由一次再生后废旧沥青混合料、新制沥青混合料、再生剂和强韧化纤维等材料拌和而成，具有优异的抗滑耐久性和抗裂性能，经过5万次磨耗后其抗滑摆值BPN大于52，基于半圆弯拉实验的断裂能大于3000J/m2。与其他的二次热再生沥青混合料相比，本发明制备的二次再生料的防滑抗裂性能得到大幅提升，能够延长二次就地热再生沥青路面的服役质量和使用寿命，具有节能环保等突出优势。
