Construction method of subbase of highway pavement
The invention discloses a construction method of a subbase layer of a highway pavement, and particularly relates to the technical field of building construction, and the construction method comprises the following steps: step 1, cleaning and trimming the surface of the subbase layer, step 2, recovering a center line, step 3, paving cobblestones and reinforced concrete on the surface of the subbase layer, step 4, adding a thermal insulation layer and an anti-crack layer, and step 5, stacking a conventional mixture. According to the construction method, on the basis of original conventional mixture laying construction, the cobblestones and the reinforced concrete are fully mixed and coagulated by laying the cobblestones and the reinforced concrete, so that a powerful supporting surface is formed on the surface of the bottom of the subbase layer, and the overall pressure resistance of a highway pavement is improved; meanwhile, the thermal insulation mixture and the anti-cracking mixture are additionally arranged on the basis of the subbase layer, so that the influence on the highway pavement caused by frost cracking of the bottom of the subbase layer due to cold weather is avoided, and the high strength, the high thermal insulation property and the high anti-cracking property of the highway pavement are improved on the basis of not influencing conventional construction.
本发明公开了一种公路路面底基层的施工方法，具体涉及建筑施工技术领域，包括步骤一、对底基层表面进行清扫，休整，步骤二、恢复中线，步骤三、底基层表面铺设鹅卵石和加强混凝土，步骤四、增加保温层以及抗裂层，步骤五、堆放常规混合料。本发明通过在原有铺设常规混合料施工的基础上，通过铺设鹅卵石以及加强混凝土，使鹅卵石与加强混凝土之间充分混合并凝结，从而使底基层底部的表面形成强有力的支撑面，提高公路路面整体的抗压性，同时在其基础上增设了保温混合物以及抗裂混合物，避免因天气寒冷使底基层底部造成冻裂，对公路路面造成影响，进而在不影响常规施工的基础上提高公路路面的高强度性、高保温性以及高抗裂性。
