The Laser Dynamic Deflection Measurement System based on the theory of laser Doppler velocity (LDV) measurement, it employs laser non-contact sensors to measure the pavement settlement velocity at a normal traffic speed, and transforms the pavement deflection via elasticity mechanics models to calculate the deflection at each detected point. The system features high efficiency, accuracy, sampling frequency, safety, and cost performance. Merely two individuals are needed to complete the measurement task achieving 500km per day.

Operating speed: the system can continuously perform detection for 8-10h at the speed of 80km/h,Significantly reduce data updating time for road deflection at road network level and project level;High data accuracy: dependencies of detection data R≥90%. Avoid the human error of traditional detection methods;System stability: free work in the complex environment such as plateau, high cold, high temperature and high humidity;Mountain road, municipal road and other road ;Wide application performance: Provide testing services for more than 30 provinces and cities in China, with a service mileage of more than 600,000 kilometers. (Add at least 50,000 kilometers per year).

• First in China, Second in the world
