Winter asphalt pavement hot mixing and warm paving construction process
The invention relates to the field of road construction, in particular to a winter asphalt pavement hot mixing and warm paving construction process which comprises the following steps: S1, construction preparation; s2, mixing and stirring materials: mixing basalt aggregate, SBS modified asphalt, a warm mixing agent and water, heating and stirring, and controlling the discharging temperature at 170-190 DEG C; s3, transporting, wherein the temperature of the asphalt mixture is not lower than 170 DEG C after the asphalt mixture is transported to a construction site; s4, paving is conducted, specifically, a traditional pavement paver is used, and an ironing plate is heated to 90 DEG C or above before construction; s5, rolling is conducted, specifically, a rubber tire type road roller is adopted for primary rolling and secondary rolling, rolling is started when a surface layer is not stuck to a wheel, the primary rolling starting temperature is 130-140 DEG C, rolling is conducted 2-3 times, the secondary rolling starting temperature is 100-110 DEG C, rolling is conducted 3-4 times, a steel wheel road roller is adopted for final rolling, the rolling starting temperature is 70-80 DEG C, and rolling is conducted 2-4 times; and S6, detecting. The compaction effect same as that of construction in a normal-temperature environment is guaranteed, and the construction time is further prolonged.
本申请涉及道路施工的领域，尤其是涉及冬季沥青路面热拌温铺施工工艺，其包括：S1，施工准备；S2，混合拌料，将玄武岩集料、SBS改性沥青、温拌剂和水混合进行加热搅拌，出料温度控制在170‑190℃；S3，运输，沥青混合料运输至施工现场后温度不低于170℃；S4，摊铺，使用传统的路面摊铺机，施工前熨平板加热至90℃以上；S5，碾压，采用橡胶轮胎式压路机进行初压和复压，在面层不粘轮时开始碾压，初压开始温度为130‑140℃，碾压2‑3遍，复压开始温度为100‑110℃，碾压3‑4遍，采用钢轮压路机进行终压，碾压开始温度为70‑80℃，碾压2‑4遍；S6，检测。本申请保证了与在常温环境下施工相同的压实效果，进一步延长了可施工时间。
