Cement concrete pavement detecting system that comes to nothing based on beckman beam method

The utility model belongs to the technical field of road surface nondestructive test, involve a cement concrete pavement detecting system that comes to nothing based on beckman beam method. It includes beckman beam deflection detector, standard car and deflection measurement station, 4 board angular positions of every cement concrete pavement panel that awaits measuring are equipped with a deflection measurement station, the deflection measurement station is apart from cement concrete pavement panel transverse joint 40cm, longitudinal joint 10cm, is the gauge head of beckman beam deflection detector placed and is organized outside center preceding partially 3 at the double round the 5cm position, the standard car more is close to road surface central authorities for the deflection measurement station. Compared with the prior art, the utility model is simple in operation, detection speed is very fast, use cost is lower, the suitability is stronger, easily promotes moreover, to the timely judgement cement concr
