Abstract

The invention provides a self-sensing pavement structure of a road or a bridge, belonging to the technical field of traffic monitoring. The invention solves the problem that the external or internal sensors adopted for monitoring the traffic data at present have high manufacturing cost and short service lives. The self-sensing pavement structure comprises a self-sensing concrete material layer, a plurality of electrodes and leading-out leads, wherein the electrodes are embedded inside the self-sensing concrete material layer; each electrode is led out of the self-sensing concrete material layer via the leading-out leads; the embedded depth of the electrodes is more than 1cm; the distance between the electrodes and the bottom surface of the self-sensing concrete material layer is also more than 1cm; and the thickness of the self-sensing concrete material layer is 3-15cm. The self-sensing pavement structure is suitable for monitoring the traffic parameters.

Description

technical field [0001] The invention relates to a road surface structure of a road or a bridge with a self-sensing function, and belongs to the technical field of traffic monitoring. Background technique [0002] Monitoring traffic parameters such as traffic flow, vehicle speed and vehicle weight on the road surface or bridge surface is an effective means to ensure the safety and smoothness of traffic in cities and highways. The existing monitoring method for traffic data is to use external or built-in magnetic, optical, electrical or microwave sensors. This type of external sensor has complex layout, high cost, high maintenance cost and poor reliability in bad weather. And other shortcomings, while the built-in sensor mainly has the disadvantages of poor compatibility with the road surface or bridge deck structure, difficult maintenance, and short service life. Contents of the invention [0003] The purpose of the present invention is to solve the problems of high cost a...
