Abstract

The invention provides an asphalt pavement pressure generator embedding method and belongs to the technical field of highway engineering piezoelectric pavement paving. The method includes the steps that basic point localization, fixed point pit excavation, circuit slotting, pressure generator embedment, wire embedment and antiskid coating laying. A road section suitable for pressure generator embedment is selected, two fixed point piles A and B are driven to the positions outside a road shoulder of the road section, the distance dA between each point and the point A and the distance dB between each point and the point B are measured and recorded, after a face layer of the road section is laid, the point A and the point B are measured, compared with data recorded previously, reserved embedding points of pressure generators are found, a pit is excavated in each embedding point, and each pressure generator is placed in the corresponding pit, cushioned flatly and fixed through asphalt mastic and then encapsulated through a gap sealing and filling material. The gap sealing and filling material is obtained by compounding SBS modified asphalt and compound modified kieselguhr. Embedding links are tightly combined, a construction technology is simple, the pressure generators can be effectively fixed, damage to a pavement is greatly reduced, and embedding work of the pressure generators is effectively guided.

Description

technical field

[0001] The invention relates to a method for embedding an asphalt pavement pressure generator, which belongs to the technical field of highway engineering construction. Background technique

[0002] Pressure power generation has the advantages of simple structure, no heat generation, no electromagnetic interference, no pollution, and easy miniaturization and integration, and can meet the power demand of low energy consumption products. The core content of the piezoelectric technology for asphalt pavement is to convert the vibration energy of the vehicle during driving on the asphalt pavement into electrical energy through the piezoelectric energy harvesting device. This requires that the pressure generator should be embedded in the surface layer of the asphalt pavement, but burying the pressure generator will inevitably cause damage to the asphalt pavement, and there are very few engineering examples of pressure power generation, and its buried construction m...
