Embodiment

[0024] Pavement Stress and Strain Detection Method

[0025] One, as attached figure 1 , 2 As shown, the asphalt layer strain sensor 1, earth pressure cell 2, temperature sensor 3 and shaft sensor 4 are pre-embedded on the test road

[0026] Asphalt layer strain sensor 1 (asphalt strain gauge produced by Construction Technology Laboratory (CTL)):

[0027] Twelve asphalt layer strain sensors 1 are pre-embedded at the position of the outer wheel track line 21 at the bottom of the asphalt mixture 10 layers. The asphalt layer strain sensors 1 are arranged in 4 rows and 3 columns along the driving direction. The first row and the fourth row are buried vertically, the asphalt layer strain sensor 1 is parallel to the driving direction, and the longitudinal strain can be obtained; the second and third rows in the middle are buried horizontally, and the asphalt layer strain sensor 1 is perpendicular to the driving direction, and the lateral strain can be obtained. The distance betwe...

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

technical field [0001] The invention relates to the field of asphalt pavement structural performance research, in particular to a pavement stress and strain detection method. Background technique [0002] 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 [0003] 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 view of the above-mentio...
