Abstract

The invention discloses a method for automatically measuring a pavement water permeability coefficient and a device therefor. The method includes mounting a water storage tank provided with a water pressure collecting device at the bottom of a water containing measuring cylinder, communicating the water storage tank with a pedestal provided with a cavity, subjecting the pedestal and a pavement to be measured to water sealing treatment so as to form a water sealed path among the water containing measuring cylinder, the water storage tank, the cavity and the pavement to be measured, collecting water pressure parameters at different times by utilizing the water pressure collecting device during a period of measuring the water permeability coefficient of the pavement to be measured, and determining the water permeability coefficient of the pavement to be measured by utilizing the collected water pressure parameters at different times. The method and the device achieve fully-automatic measurement of the pavement water permeability coefficient and are free of manual operation, accurate and reliable in measuring results and relatively stable. The device is simple in overall structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of pavement performance detection, in particular to a water seepage performance detection technology applied to asphalt mixture pavement. Background technique [0002] The water seepage performance of asphalt pavement is an indirect index reflecting the gradation composition of asphalt mixture on pavement, and it is also an important index of water stability of asphalt pavement. According to the requirements of Chinese standards, the water seepage performance of asphalt pavement is expressed by water seepage coefficient. The water seepage coefficient index is of great significance for improving the construction quality of asphalt pavement, measuring the traffic condition of asphalt pavement, preventing water damage of asphalt pavement, and carrying out reasonable pavement maintenance. [0003] At present, the measurement method of water seepage coefficient is that when the water volume of the measuring cylin...
