Method for repairing road surface

Abstract

The invention discloses a method for repairing a road surface. The method comprises the following steps: initializing to set the reasonably lifted range value of elevation and the excavation range and depth of an original road surface, the reasonable thickness range value, the cross slope standard value and the reasonable variation range value of a newly-built road surface, and the longitudinal and transverse geometric linear parameters of the original road surface; determining a center line designed for the road; determining control points and corresponding checking points on the designed center line; measuring the elevation values of the original road surface at the control points and the checking points; determining the repaired elevation values at the control points; determining the actual cross slope values at the control points; calculating the repaired elevation values at the checking points; calculating the thickness of structural layers of the proposed new road surface at thechecking points so as to determine whether the thickness can meet the requirement for the reasonable thickness range value; and outputting pile numbers, the repaired elevation values and the corresponding cross slope values at all the control points. In the method, by means of collaborative design of vertical and horizontal sections and synchronous consideration of the thickness of the structurallayers, and the quality of the road surface structure is ensured while the line shape of the original road is recovered, thus achieving the purpose of saving later maintenance cost.

Description

technical field [0001] The invention relates to a pavement repair technology, in particular to a method for large and medium pavement repairs. Background technique [0002] When there is a large area of ​​disease on the pavement and the pavement structure is seriously damaged, major and medium repairs are required to restore the technical condition of the pavement and prolong the service life of the pavement. The current major and medium repair of asphalt pavement has the following defects in the design of the longitudinal and transverse sections when formulating the technical plan: it basically does not involve the design of the longitudinal and transverse sections or is only designed independently, and in the design of the longitudinal and transverse sections. Consider the practicability of the proposed pavement structure layer combination and the thickness of each layer. This kind of design has no practical guiding significance for the site, so there are often large adju...

Problems solved by technology

The current major and medium repair of asphalt pavement has the following defects in the design of the longitudinal and transverse sections when formulating the technical plan: it basically does not involve the design of the longitudinal and transverse sections or is only designed independently, and in the design of the longitudinal and transverse sections. Consider the practicability of the proposed combination of pavement structural layers and the thickness of each layer

This kind of design has no practical guiding significance for the site, so there are often large adjustments during the site construction, resulting in the thickness of the new pavement structure being too thick or too thin, which is not conducive to ensuring the compaction quality of the site construction and weakening the strength of the repaired pavement structure. Buried hidden dangers; also brought many adverse effects to the management of on-site construction in terms of construction period and investment
