Quick and nondestructive testing method for road axle load spectrum

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.
