Full-slope barrier-free enterprise intersection construction process
The invention discloses a full-slope barrier-free enterprise intersection construction process which comprises the following steps: step 1, firstly, paving a C20 concrete base layer with the thickness of 15cm, and then paving an AC-10 fine-grain asphalt surface layer with the thickness of 5cm on the C20 concrete base layer; step 2, drawing greenway width dotted lines, and then planing and paving an AC-13 fine-grained asphalt surface layer with the thickness of 5cm in the intersection range; step 3, marking a sidewalk width zebra crossing; the arranged concrete base layer has the advantages of being excellent in compression resistance and high in splitting strength; asphalt in the asphalt surface layer is formed by adding waste tires and butadiene styrene rubber into matrix asphalt, shearing and grinding at high temperature and then developing, low-temperature flexibility is good, viscosity and rutting resistance are good, and the service life of the asphalt surface layer is prolonged. Due to the use of the styrene-butadiene-styrene block copolymer, the ethylene-vinyl acetate copolymer and the polyethylene, the asphalt is excellent in skid resistance and bearing capacity, is beneficial to laying and use, and is long in service life, and meanwhile, the cost is reduced.
本发明公开了一种全坡无障碍式企业路口施工工艺，包括以下步骤：步骤一：先铺设15cm厚的C20混凝土基层，然后在C20混凝土基层的上面铺设5cm厚的AC‑10细粒式沥青面层；步骤二：划绿道宽度虚线，然后在路口范围刨铺5cm厚AC‑13细粒式沥青面层；步骤三：划人行道宽度斑马线；设置的混凝土基层具有抗压性能优良和劈裂强度高的优点；设置的沥青面层中的沥青利用废旧轮胎和丁苯橡胶加入基质沥青中，高温剪切研磨，再发育而成，低温柔韧性好，黏度和抗车辙性好，还有苯乙烯‑丁二烯‑苯乙烯嵌段共聚物、乙烯‑醋酸乙烯共聚物和聚乙烯的使用使得该沥青抗滑和承载能力优越，利于铺设使用，使用寿命长，同时降低了成本。
