Research on Whole-Set Equipment for Detection of Road Structure Status and Environment Parameters

Performances of asphalt pavement structure depend on response status of pavement under effect of load and environment. The existing pavement response model is designed mainly based on the theoretical calculation and previous experience, and there exists bigger deviation from actual situation. How to identify and quantify key response parameters influencing pavement structure and environmental factors influencing performances of pavement always constitutes a major technical challenge in the field of road engineering. Based on the above research, this complete set of equipment has developed an automatic control system of interlayer shear movement on the road surface, which has realized accurate and constant control on the axial force between the road surface layers and improved the test ability of interlayer shear force on the road surface. This equipment can carry out intelligent collection of response parameters at the road level, which has realized automatic collection and large-capacity storage of multi-channel dynamic response parameters between layers, improved detection efficiency and accuracy, optimized data processing model, and improved analysis and monitoring. At the same time, the equipment can automatically monitor the environmental parameters of roadbed road surface for a long time, which has improved monitoring efficiency for road environment parameters.
