Abstract:
     The present invention relates to a test equipment for measuring the deflection of airport runway pavement belonging to the field of photoelectric measurement to non-electric parameters. Said laser pavement deflection test vehicle can directly measure the deflection of rigid pavement or flexible pavement in airport and is applicable to military airfield and departments of civil aviation, communication and municipal engineering. The safety of aircraft take-off and landing is directly related to the quality of runway pavement and the bearing capacity of runway pavement is of great importance to new-built airport or originally used airport. Said invention can calculate the pavement bearing capacity by means of measuring pavement deflection so as to collect the feedback information required for improving pavement designing method and maintenance and provide necessary data.
