Asphalt pavement structure capable of relieving reflection cracks of semi-rigid base and paving method
The invention discloses an asphalt pavement structure capable of relieving reflection cracks of a semi-rigid base and a paving method, and belongs to the field of road engineering. The pavement structure is characterized in that a thin-layer graded broken stone stress absorption layer is arranged between a cement stabilized broken stone structure layer and an asphalt structure layer, the thickness of the thin-layer graded broken stone stress absorption layer is 8-11 cm, the particle size of broken stone is 0-26.5 mm, after the cement stabilized broken stone structure layer is rolled and formed, cement paste is sprayed immediately, and the asphalt structure layer is formed after the cement stabilized broken stone structure layer is rolled and formed. And continuously paving the thin-layer graded broken stone stress absorption layer, and then synchronously rolling and forming the cement stabilized broken stone structure layer and the thin-layer graded broken stone stress absorption layer with the compaction degree of 100%. The asphalt pavement structure can effectively relieve damage of reflection cracks of the semi-rigid base layer structure to the asphalt structure layer, the overall service life of the pavement structure is prolonged, the service quality of the pavement structure is improved, and good application and popularization value is achieved.
本发明公开了一种能够缓解半刚性基层反射裂缝的沥青路面结构及铺装方法，属于道路工程领域。所述路面结构的特点是在水泥稳定碎石结构层和沥青结构层之间设置有薄层级配碎石应力吸收层，所述薄层级配碎石应力吸收层的厚度为8cm～11cm，碎石粒径为0‑26.5mm，水泥稳定碎石结构层碾压成型后，立刻喷洒水泥浆，并连续摊铺薄层级配碎石应力吸收层，然后，水泥稳定碎石结构层和薄层级配碎石应力吸收层同步碾压成型，压实度100％。本发明的沥青路面结构能够有效缓解半刚性基层结构反射裂缝对沥青结构层的损坏，提升路面结构整体寿命与服务质量，具有很好的推广应用价值。
