A wharf concrete road structure and its construction method

Abstract

A wharf concrete road structure, on which a cushion, a base course and a surface course are respectively laid on the roadbed, and the upper part of the surface course has horizontally and vertically distributed steel bars. Driveway slabs, dowel bars are placed in the middle of the longitudinal and transverse joints between the driveway slabs, the driveway slabs are divided into wheel pressure areas and non-wheel pressure areas, and the upper edge of the wheel pressure area is equipped with compression steel bars, and the lower edge is clothed with Bending reinforcement, with longitudinal reinforcement in the middle of both sides, tension reinforcement between compression reinforcement and bending reinforcement, compression reinforcement, bending reinforcement and middle longitudinal reinforcement outside stirrups; surface layer surface with non-wheel compression area and wheel Nip identification. Carry out joint cutting and caulking, and draw identification marking lines after the construction of road bed, cushion, base layer and surface layer in sequence. The road guides vehicles to drive along the wheel pressure zone with strong bending and cracking resistance through marking lines, so that the road can withstand the load of container vehicles with heavy traffic and heavy axle loads, and ensure the safety and durability of the surface layer.

Description

technical field [0001] The invention relates to road engineering, in particular to a wharf concrete road structure for running container heavy-duty trucks and a construction method thereof. Background technique [0002] Whether it is a passenger car or a truck, the entire weight of the body is transmitted to the road through the wheels on the axle. Therefore, for the road surface, great importance is attached to the axle load of the car. At present, the rear axle load of trucks running on highways in our country is generally controlled within the range of 60-130kN. The current road and urban road pavement design specifications in my country use 100kN as the design standard axle load. [0003] The degree of damage to the pavement structure caused by axle loads of different gravity is different. In the design of road structures, in addition to considering the cumulative traffic volume of the road within the design period, the proportion of axle loads at all levels must also b...

AI Technical Summary

Problems solved by technology

The safety and durability of this kind of concrete road structure is difficult to be guaranteed due to the large cumulative traffic volume, the axle load of vehicles and the total weight.
