Abstract

The invention discloses a pavement water-seepage standard device and a pavement water-seepage coefficient measurement method, and overcomes the deficiencies that measurement standards of a conventional pavement water-seepage meter are deficient, and a measurement value cannot trace to a source. The device comprises a water-seepage container (10), monitors (30), a timer (40) and a controller (50); the monitors (30) are used for monitoring a volume change of a liquid in the water-seepage container (10); the timer (40) is used for recording the water-seepage time corresponding to the volume change; the controller (50) is used for calculating to obtain a water-seepage coefficient according to the volume change and the water-seepage time. The pavement water-seepage standard device and the pavement water-seepage coefficient measurement method greatly improve the standardization degree of the pavement water-seepage meter, realize full automation of the water-seepage coefficient measurement process, have rapid response and high accuracy, can realize verification and calibration of water-seepage coefficient measurement errors, measurement repeatability and other key measurement parameters, and can trace to the source of the quantity value of the pavement water-seepage meter on the significance of metrology.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a road surface seepage standard device and a method for measuring the road surface water seepage coefficient. Background technique [0002] Pavement water seepage coefficient is one of the key technical indicators to measure the drainage performance of asphalt pavement and asphalt mixture. The pavement water seepage coefficient is directly related to the traffic safety of asphalt pavement in rainy days. Generally, a pavement seepage coefficient tester (also called a pavement seepage meter) is used to measure the pavement seepage coefficient. Pavement seepage coefficient is generally expressed by the volume of water infiltrated into the pavement per unit time, and its unit is generally milliliters per minute (mL / min). [0003] With the development of the transportation industry, the pavement drainage performance has been paid more and more attention. The research on drainage asphalt mixt...
