Quick and nondestructive testing method for road axle load spectrum

Abstract

The invention discloses a quick and nondestructive testing method for a road axle load spectrum, wherein the method belongs to the field of road engineering prospection and design. The quick and nondestructive testing method is a full-section axle load spectrum which is performed without traffic interception. Furthermore representative traffic load sample data are acquired, thereby supplying traffic load data which accord with an actual traffic load condition for road surface maintenance design and preventative maintenance decision. Compared with the prior art, the quick and nondestructive testing method for the road axle load spectrum has advantages of high mounting speed, no pavement damage, high movement flexibility, effective recyclability, etc. The quick and nondestructive testing method can be used for performing axle load investigation on a designed road, thereby obtaining an actual driving load, truly reflecting pavement load condition of the road, and supplying reliable design basis for road engineering design. Furthermore the quick and nondestructive testing method has important function and meaning on prolonging service life of the pavement structure, reducing full-cycle cost of the road and promoting environment-friendly traffic transportation construction.

Description

technical field [0001] The invention relates to the field of road engineering survey and design, in particular to a fast and non-destructive detection method of road shaft load spectrum. Background technique [0002] The role of vehicle load is the key to affect the performance and service life of pavement. Traffic load is the most important factor in the process of pavement structure design and analysis, and it is also the most variable and most difficult to predict factor. Different types and loaded vehicles will produce different levels of axle loads, which will have different impacts on the road surface. Therefore, road designers are not only concerned about the traffic volume, but more importantly, the size of the axle load and the number of axle loads at all levels. However, the existing solution is to divide all vehicles in the traffic flow into several types, and then select a representative model for each type of vehicle, and calculate the equivalent axle load conv...

Problems solved by technology

This method can only reflect the situation that the vehicle is loaded and driven according to the rated loading tonnage and uniform loading method, but it cannot reflect the axle load changes caused by the overload of the vehicle and uneven loading of goods, and these two situations are in the existing road. is ubiquitous in operation
