Foam and emulsified asphalt cold regeneration warm forming continuous paving pavement surface layer construction method
The invention relates to a foam and emulsified asphalt cold regeneration warm forming continuous paving pavement surface layer construction method, and belongs to the technical field of asphalt paving, and the method comprises the following steps: S1, mix proportion preparation: before regenerated pavement construction, firstly obtaining an original pavement material RAP, determining the technical indexes of the regenerant and the active material and the proportion of various admixtures through tests; s2, traffic closing and lower bearing layer preparation: closing a construction area, removing sundries on the surface of an original road, pre-shaping the original road, and adjusting a cross slope and a longitudinal slope line of the original road; s3, paving the foam (emulsified) asphalt cold-recycled mixture: paving the cold-recycled mixture by using a construction instrument; s4, rolling and pre-forming are conducted, specifically, a rolling scheme is formulated according to the road width and the difference of the wheel width and the wheel tread of a road roller, and the road roller conducts rolling on the road surface; s5, paving a hot asphalt mixture: paving the hot asphalt mixture after the lower cold regeneration layer is formed to exceed 100m; s6, rolling and warm forming: rolling asphalt concrete when the temperature of the common asphalt mixture is 100-120 DEG C; and S7, curing, acceptance and traffic opening: the hot asphalt layer and the regeneration layer are combined to form a warm forming combination layer to accelerate demulsification and hardening of the regeneration layer, and when the surface temperature of the combination layer is lower than 50 DEG C, social traffic is opened. The method has the effect of reducing the construction period.
本申请涉及一种泡沫及乳化沥青冷再生温成型连铺路面面层施工方法，属于沥青铺路的技术领域，其包括以下步骤：S1、配合比准备：再生路面施工前首先需要取得原路面材料RAP，通过试验确定再生剂及活性材料技术指标以及各类掺料之间的比例；S2、封闭交通，下承层准备：对施工区域进行封闭，清除原道路表面的杂物，对原道路进行预整形，原道路的横坡、纵坡线进行调整；S3、泡沫（乳化）沥青冷再生混合料摊铺：使用施工器械对冷再生混合料进行摊铺；S4、碾压初成型：根据路宽、压路机的轮宽和轮距的不同，制订碾压方案，压路机对路面进行碾压；S5、热沥青混合料摊铺：当下部冷再生层成型超过100m后，进行热沥青混合料摊铺；S6、碾压温成型:常用沥青混合料待待温度100‑120℃时，即可进行沥青砼的碾压;S7、养生、验收及开放交通：热沥青层与再生层结合形成温成型结合层加速再生层破乳板结，当结合层表面温度低于50℃时，开放社会交通。本申请具有减少施工周期的效果。
