Milling and re-paving construction process suitable for expressway pavement
The invention discloses a milling and re-paving construction process suitable for an expressway pavement. The construction process comprises the following construction processes: surveying and setting out, cutting, milling, cleaning, spreading emulsified asphalt, blending an asphalt mixture, transporting the asphalt mixture, paving the asphalt mixture, rolling and opening traffic. In the process of paving theasphalt mixture, the mixed material is checked on site to ensure that the temperature of the mixed material is 145-165 DEG C, the proceeding speed of a paver is 2.5-3.5 m/min, the construction paving temperature is controlled to be 135-160 DEG C, and the construction paving temperature is controlled to be 140-165 DEG C at low temperature; the paving thickness is not lower than the designed thickness; and the asphalt concrete paving coefficient is 1.18-1.21 according to the paving data of the test section. The original road is upgraded, the comfort and the road appearance of the road are improved, the problem that the original road has a disease section is solved by milling the original road and re-paving the original road, the road surface quality is improved, the driving condition is optimized, the service life of the road is prolonged, and the requirements of economic development are met.
本发明公开了一种适用于高速道路路面铣刨重铺施工工艺，通过测量放线→切割→铣刨→清理→撒布乳化沥青→沥青混合料拌和→沥青混合料的运输→沥青混合料的摊铺→碾压→开放交通的施工工艺，在沥青混合料的摊铺过程中，对到场的混合料进行检验，确保混合料温度在145～165℃之间，摊铺机的进行速度为2.5‑3.5m/min，施工摊铺温度控制在135～160℃，低温时控制在140～165℃；摊铺厚度不低于设计厚度；根据试验段摊铺数据沥青砼摊铺系数为1.18～1.21，本发明实现了对原道路提档升级打造，提高道路的舒适性和路容路貌，通过对原道路铣刨并重新摊铺，解决了原道路存在病害地段的问题，提高了路面质量、优化了行车条件、延长了道路使用寿命，适应经济发展的需要。
