Zusammenfassung: | 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 st |
