Construction method for municipal road, pavement structure and road pavement

Abstract

The invention discloses a municipal highway, a road surface structure and a construction method of the highway pavement, including the highway, on which there are altogether an epoxy resin asphalt layer, an FRT layer, a concrete layer, coal gangue, a lime layer, a slag soil base, steel bars, Reinforced grid mesh, pouring vertical steel columns inside the road, so as to avoid the dislocation between the road surface and the roadbed after a long time, the upper surface of the lime layer is bonded to the middle layer of the paved road surface and the asphalt concrete on the upper layer of the road surface and pressed together In fact, during road construction, because the FRP waterproof layer has good water resistance, it can avoid the uneven settlement caused by the accumulation of water penetrating into the roadbed, and then can ensure the smoothness of the road surface. The epoxy resin laid on the surface of the road The asphalt layer makes the road surface have good ductility, so that the road surface will not crack during the long-term extrusion.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a construction method of a municipal road, a road surface structure and a road surface. Background technique [0002] Highways refer to roads connecting cities, between urban and rural areas, between villages and villages, and between industrial and mining bases, which are built in accordance with national technical standards and approved by the competent highway department, including expressways, first-class roads, and second-class roads , third-class roads, and fourth-class roads, but does not include trails naturally formed in fields or rural areas. It is mainly used for cars and has certain technical standards and facilities. Highway is an important part of the whole transportation. In short-distance transportation, highway can be used as distribution line to make up for the shortage of railway, water transportation and air transportation. In long-distance transpor...

Problems solved by technology

However, in many areas, especially in rural areas, most of the places where roads are laid are agricultural and forestry lands, where it is difficult to use electricity for construction, and the transportation distance is long. Water is a serious defect, and it is easy to fail to complete the process within the cement initial setting time
