Long-acting type pavement anti-skid layer
The invention relates to the technical field of road engineering materials, in particular to a long-acting type pavement anti-skid layer which comprises, by weight, 85-99% of anti-skid aggregate, 1-15% of hard asphalt and 0.5-3% of surfactant, the particle size of the anti-skid aggregate is smaller than or equal to 16 mm, the mass ratio of the part below a 13.2 mm sieve and above a 9.5 mm sieve is 25-35%, and the mass ratio of the part below a 9.5 mm sieve and above a 2.36 mm sieve is 42-50%. The bonding strength between the hard asphalt and the aggregate on the anti-skid surface layer is high, and the hardness of the hard asphalt cementing material is high. The transverse force coefficient SFC can be increased by about 20%, the long-term abrasion resistance is excellent, the annual attenuation rate is not larger than 10%, and the road traffic safety problem caused by insufficient road surface skid resistance is solved.
本发明涉及道路工程材料技术领域，具体为一种长效型路面抗滑层，按重量百分比包括：抗滑集料85～99％、硬质沥青1～15％和表面活性剂0.5～3％，所述抗滑集料的粒度≤16mm，其中，13.2mm筛下9.5mm筛上部分的质量占比为25～35％，9.5mm筛下2.36mm筛上部分的质量占比为42～50％。本发明抗滑表层硬质沥青‑集料间的粘结强度高，硬质沥青胶结料硬度高。可以提升横向力系数SFC约20％，长期抗磨耗性能表现优异，年衰减率不大于10％，解决了路面抗滑性能不足导致的道路交通安全问题。
