Road water stain dense position distinguishing method based on density peak value method

Abstract

The invention discloses a road water stain dense position distinguishing method based on a density peak value method, which comprises the following steps: (1) carrying out data acquisition on an asphalt pavement to obtain the distribution condition of water stains in an asphalt pavement structure; (2) obtaining X-axis and Y-axis values of water stain dense points which are not detected by using an interpolation method; (3) calculating the obtained complete data to obtain the distance dij between the water spot dense points; (4) obtaining the distribution density rho i of the water stain dense points in the local range based on the distance dij between the water stain dense points and a density formula; (5) calculating the distance delta i between the dense point i of the water spots and the dense points j of the other water spots; and (6) based on the obtained distribution density rho i and distance delta i of the water spot dense points, selecting i sample data serial numbers as codes, and drawing a scatter diagram with rho as a horizontal coordinate and delta as a vertical coordinate, the road maintenance efficiency can be improved, the road maintenance cost can be reduced, and the method has profound significance for preventive maintenance of roads.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a method for identifying dense locations of road water spots based on a density peak method. Background technique [0002] The economic status of a city is closely related to the road traffic network in the surrounding areas of the city. With the development of the city economy, the traffic volume carried by the road is increasing day by day, which leads to the increasing aggravation of different road diseases. In the long service life of the road, there are many factors that cause pavement diseases, and the post-rain water damage inside the road structure is one of the important factors. At present, the existing asphalt pavements in urban roads are mostly semi-rigid pavements, and semi-rigid pavements have poor drainage, and it is difficult to drain the free water inside the pavement structure in a short time, which makes the roads prone to water accumulation. The phen...

Problems solved by technology

At present, the existing asphalt pavement in urban roads is mostly semi-rigid pavement, and the drainage of semi-rigid pavement is poor, and it is difficult to drain the free water inside the pavement structure in a short time, resulting in roads that are prone to flooding when water accumulates. Phenomenon of sloshing and pitting

Therefore, water damage after rain is more harmful to semi-rigid pavement
