Method for detecting stress and strain of road surface

Abstract

The invention discloses a method for detecting stress and strain of a road surface, belonging to the field of structure performance research of bituminous road surface. In the method, a bituminous layer strain sensor, a soil pressure case, a temperature sensor and a shaft sensor are embedded at the proper position of the road to be tested; and the data collected by a high-speed data collecting system is analyzed and processed to obtain the stress and strain of the road surface. The data measured by the method can reflect the actual situation of the road surface and has favorable values for promotion and application. The invention can be widely applied to the stress state, change rule and detection technology research inside the road surface under the action of traffic load and the coupling action of environmental variation.

Description

Pavement Stress and Strain Detection Method technical field The invention relates to the field of asphalt pavement structural performance research, in particular to a pavement stress and strain detection method. Background technique With the in-depth research on asphalt pavement design based on mechanics, pavement testing instruments have become an important tool to observe the performance decay of pavement materials and the response of pavement structure under load. However, in the prior art, the arrangement and arrangement of the sensors are not well considered, and the measured data cannot well conform to the actual conditions of the road surface. In addition, the way the sensors collect data is also intermittent rather than continuous. Contents of the invention The technical task of the present invention is to provide a road surface stress and strain detection method with accurate data measurement and more in line with the actual situation of the road surface in vi...
