Roadbed structure suitable for single-side heavy traffic transportation

Abstract

The invention discloses a roadbed structure suitable for single-side heavy traffic transportation. The roadbed structure comprises a roadbed structure layer, a road center line of the roadbed structure layer is divided into a light-load amplitude roadbed structure layer and a heavy-load amplitude roadbed structure layer, the laying thickness of the heavy-load amplitude roadbed structure layer, a base layer and a bottom base layer is larger than that of the light-load amplitude roadbed structure layer, the base layer and the bottom base layer respectively; the surface layer of the heavy-load amplitude roadbed structure layer and the surface layer of the light-load amplitude roadbed structure layer extend downwards from the center line of the road surface to form a right gear table and a left gear table, the base layer of the heavy-load amplitude roadbed structure layer is laid on the right side of the right gear table, and the bottom base layer of the heavy-load amplitude roadbed structure layer extends from the left side of the left gear table to the right to be laid. The roadbed structure has the advantages that the structure is ingenious, the load-bearing capacity of the heavy-load amplitude subgrade structure layer is good, the single-side transport requirement of the heavy-load transport vehicle is met, the service life of the heavy-load amplitude roadbed structure layer isprolonged, the repair period is prolonged, and the repair cost is reduced.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a roadbed structure suitable for single-side heavy-duty traffic transportation. Background technique [0002] In mine operation and water conservancy project construction, it is usually necessary to lay special roads for entry and exit to meet the heavy-duty transportation needs. Existing special roads for entry and exit are generally two-way and one-sided heavy-duty transport roads, that is, heavy-duty vehicles drive on a certain half of the road for a long time, and returned light-duty vehicles travel on the other half of the road for a long time. Therefore, during the operation of the special road for entry and exit, it has been in an unbalanced load state. The half-width road surface and roadbed of heavy-duty vehicles are damaged prematurely, while the half-width road surface and roadbed of light-loaded vehicles are still intact. In order to ensure transportation, it is usual...

Problems solved by technology

In order to ensure transportation, it is usually necessary to carry out structural repairs on the pavement, which is frequent and expensive, and affects normal traffic during the repair process

Due to the long-term unbalanced load state of the entry and exit roads, the service life of the road is short. When the half-width road surface and roadbed of heavy-duty vehicles are seriously damaged, it is usually necessary to re-pave the entire road surface and roadbed, which will cause serious damage to half-width roads. Greater economic loss and adverse social impact, but for the intact half-width road surface and roadbed, there is hidden waste
