Abstract

The invention discloses a pavement structure durability and dynamic traffic monitoring system. The pavement structure durability and dynamic traffic monitoring system comprises a first load sensor, a second load sensor, a constant voltage source, a signal amplifier, a data acquisition instrument and a comparison device, wherein the constant voltage source is connected with the first load sensor and the second load sensor, the first load sensor and the second load sensor are both connected with the data acquisition instrument through the signal amplifier, and the data acquisition instrument is connected with the comparison device. According to the pavement structure durability and dynamic traffic monitoring system, the traffic volume and the traffic load can be monitored by analyzing collected data, the pavement damage degree can be judged at the same time, and then the durability of a pavement can be monitored; by the adoption of the constant voltage source and the signal amplifier, the change, caused by a pavement load change, of resistance of a carbon nano-tube cement-based composite material sensor can be measured accurately, and the load detection sensitivity is high.

Description

technical field [0001] The invention relates to the technical fields of engineering materials and traffic engineering, in particular to a road surface structure durability and dynamic traffic monitoring system. Background technique [0002] With the rapid development of the national economy, the transportation industry has made rapid progress. Heavy-duty traffic and speeding phenomena are not uncommon. At the same time, the phenomenon of major and medium road surface repairs has become one of the hot spots in traffic engineering. Since the intelligent transport system (Intelligent Transport System, referred to as IRS) was proposed, many countries have successively proposed their own development strategies, trying to adopt various advanced technologies to integrate people, vehicles, roads and the environment involved in the transportation system to make it Play an intelligent role, so that the traffic system can achieve the goals of safety, smoothness, low pollution and low ...
