Abstract

The invention relates to a tester and measuring method for the structural depth of a large-porosity drainage asphalt pavement, belonging to the technical field of highway engineering in traffic engineering. The tester and measuring method can accurately measure the structural depth of the surface of the large-porosity drainage asphalt pavement and avoid the phenomenon of sand leaking holes in measurement of the structural depth of the large-porosity drainage asphalt pavement with a sand patch method, so accurate data is provided for evaluation of the macroscopic structure, draining performance and like of the pavement. Moreover, the tester and measuring method can rapidly measure the structural depth of the pavement and enables manpower and material resources to be saved and work efficiency to be improved in practical engineering needing considerable measurement of the structural depth of pavements.

Description

Technical field [0001] The present invention is a highway engineering technology field in transportation engineering, which involves a large gap drainage asphalt pavement constructor and measurement method. Background technique [0002] In road engineering, the deep sand laying method and the car laser structure depth instrument are commonly used to measure the structure depth of the pavement to evaluate the macro structure on the surface of the pavement, thereby evaluating its anti -slip, drainage, noise and other performance.The price of the depth instrument in the vehicle -mounted structure is relatively high, the operation is complicated, and the test results of the test on the road with pits are affected. Therefore, the use is limited. Generally, this method is not adopted during the test.The sand laying method is to spread the known volume sand on the surface of the road to test the pavement. The ratio of the volume of sand to the coverage of the coverage is the constructin...
