Anti-crack semi-flexible pavement structure
The invention discloses an anti-crack semi-flexible pavement structure, and belongs to the technical field of pavement structures, and the pavement structure comprises, from top to bottom, an ultrathin overlay functional layer of 0.8-1.2 cm; the 1-1.5 cm anti-crack layer is formed by compounding a low-density reinforcing mesh with oxygen macadam; the thickness of the semi-flexible asphalt layer is 4-12 cm; the anti-reflection crack layer is formed by combining a 0.5-1cm low-density reinforcing mesh with the stress absorption layer; a common asphalt mixture middle surface layer with the thickness of 4-8 cm; and the thickness of the ordinary asphalt mixture lower surface layer is 8-16cm. According to the anti-crack type semi-flexible pavement structure, the technical problem that reflection cracks from bottom to top and fatigue cracks from top to bottom are likely to be generated on a semi-flexible pavement is solved.
本发明公开了一种抗裂型半柔性路面结构，属于路面结构技术领域，路面结构由上至下依次包括：0.8～1.2cm的超薄罩面功能层；1～1.5cm以低密度钢筋网复合氧碎石形成的抗裂层；4～12cm的半柔性沥青层；0.5～1cm低密度钢筋网复合应力吸收层形成的抗反射裂缝层；4～8cm的普通沥青混合料中面层；8～16cm的普通沥青混合料下面层。本发明的抗裂型半柔性路面结构，解决了半柔性路面易产生从下至上的反射裂缝和从上至下的疲劳开裂技术问题。
