Methods of road construction and maintenance

Abstract

The present invention relates to a method for highway construction and maintenance. The method includes obtaining the road information matrix R(Li, Pi) of the current road section, where Li represents the position information of the corresponding i-th road section, and Pi represents the roughness information of the corresponding i-th road section. , i is equal to 1~N; obtain the historical use information matrix U(Wni, Tni, n) of the current road section, Wni represents the weight of the nth vehicle passing through the current road section within a preset time, and Tni represents the nth vehicle weight The passing time period of the vehicle; n represents that the current road section passes n vehicles in total, and the optimal bearing capacity W0 of the current road section is set; the road section dilapidation degree Di, Di=(|W1i‑W0|+|W2i‑W0| +...+|Wni‑W0|) / (W1i+W2i+...+Wni), set the road construction maintenance urgency Gi, Gi=K1×Pi+K2×Di, K1 and K2 are constants, K1+K2= 1. The method for road construction and maintenance provided by the present invention can effectively select the time for road construction and maintenance by setting the urgency of road construction and maintenance, thereby reducing maintenance costs or road maintenance costs.

Description

technical field [0001] The invention relates to the field of urban traffic, in particular to a method for road construction and maintenance. Background technique [0002] With the rapid increase of road traffic volume, it has also brought certain challenges to the important carrier roads that carry road traffic. The proportion of trucks has increased, and the overloading phenomenon is serious, resulting in various damages to the road surface, not only serious Affected transportation, and caused huge economic losses. [0003] At present, the maintenance of the road is more and more important to whether the road can run normally, and there are more and more existing road maintenance methods, but the road maintenance methods in the prior art are relatively single for the road section, such as only for the asphalt pavement of the expressway In the face of complex road sections, there is a lack of effective maintenance methods. Moreover, how to choose the best maintenance time ...

[0002] With the rapid increase of road traffic volume, it has also brought certain challenges to the important carrier roads that carry road traffic. The proportion of trucks has increased, and the overloading phenomenon is serious, resulting in various damages to the road surface, not only serious Affected transportation and caused huge economic losses

[0003] At present, the maintenance of the road is more and more important to whether the road can run normally, and there are more and more existing road maintenance methods, but the road maintenance methods in the prior art are relatively single for the road section, such as only for the asphalt pavement of the expressway protection, lack of effective maintenance means in the face of complex road sections

Moreover, how to choose the best maintenance time for different road surfaces is also an important issue. Some road surfaces have serious cracks, which affect normal transportation. Carrying out road construction and maintenance at this time is equivalent to partially rebuilding the road surface. Time-consuming and costly
