Construction method of pavement high-viscosity asphalt thin overlay
The invention relates to the technical field of high-viscosity asphalt thin overlay, and discloses a pavement high-viscosity asphalt thin overlay construction method which comprises the following steps: 1) grouting and repairing cracks in an original pavement; (2) a milling machine is used for milling and planing to form a milled and planed road surface; (3) a sweeper is used for sweeping; (4) carrying out one-way hot air blowing drying by utilizing hot air equipment; 5) spraying an adhesive layer on the milled pavement; (6) paving a mixture on the milled pavement by using a paver, wherein the mixture is formed by stirring and mixing aggregate, mineral powder and modified asphalt; in the process of paving the mixture, the temperature of the mixture is kept higher than the set paving temperature, high-viscosity asphalt is synchronously sprayed to the paved mixture through a spraying machine, the high-viscosity asphalt is mixed in the mixture, and the mixture forms a paving layer on the milled pavement; (7) rolling by using a road roller to form a thin overlay; and (8) covering an isolating membrane layer on the thin-layer cover surface, spraying water on the isolating membrane layer, cooling to a set temperature, and removing the isolating membrane layer from the thin-layer cover surface.
本发明涉及高粘沥青薄层罩面的技术领域，公开了路面高粘沥青薄层罩面施工方法，1)、对原路面中的裂缝进行灌浆修补；2)、利用铣刨机铣刨形成铣刨路面；3)、利用清扫机清扫；4)、利用热风设备进行单向热风吹烘；5)、在铣刨路面上喷涂粘层；6)、利用摊铺机在铣刨路面上摊铺混合料，混合料为集料、矿粉以及改性沥青搅拌混合形成；在摊铺混合料的过程中，保持混合料的温度高于设定摊铺温度，利用洒布机同步往摊铺中的混合料洒布高粘沥青，高粘沥青混合在混合料中，混合料在铣刨路面上形成摊铺层；7)、利用压路机碾压形成薄层罩面；8)、在薄层罩面上覆盖隔离膜层，在隔离膜层上喷洒水体，冷却至设定温度，将隔离膜层撤离薄层罩面。
