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.
