Problems solved by technology

Under the action of hydrodynamic pressure, water will be forced into the pavement gap, thereby causing damage to the interior of the pavement structure. However, the existing pavement seepage detection devices and methods do not take into account the influence of hydrodynamic pressure on pavement seepage. a shortcoming of the field

Abstract

The invention discloses a device and a method for detecting water seepage of a dynamic water pressurizing anti-lateral seepage asphalt pavement. The device is characterized in that a to-be-tested part is arranged between a pressurizing top plate and a pressurizing bottom plate, and is reinforced by a reinforcing screw rod; the water adding or air filling pressurizing in a water seepage tank is controlled by a controller, so that pressurizing water acts on the to-be-tested part in a pulse type dynamic pressurizing mode; a lateral seepage water collection tank and a direct seepage water collection pipe are respectively used for collecting lateral seepage water and direct seepage water. The method has the advantages that the water seepage environment of the asphalt pavement in the actual use process is truly represented, the influence of lateral seepage to water seepage of the pavement is effectively avoided, and the anti-water seepage ability of the asphalt pavement is more accurately evaluated and judged.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement water seepage detection, and in particular relates to a pressurized anti-side seepage asphalt pavement water seepage detection device and method under simulated road surface dynamic water pressure. Background technique [0002] The water permeability of the pavement is an important criterion to measure the quality of the pavement, and the water permeability of the pavement structure is also an important parameter that should be considered in the analysis of its waterproof and drainage. The form and mechanism of pavement damage caused by water infiltration have been described in a large number of literatures. Therefore, the water seepage test of asphalt pavement is of great significance to the study of various factors affecting the water seepage performance of asphalt pavement, to solve the problem of water damage, to ensure the quality of asphalt pavement, and to prolong the service life ...
