Abstract

The invention relates to a detection device for detecting a drainage coefficient of a drainage asphalt pavement. The detection device comprises a liquid storage container, the interior of the liquid storage container is hollow to form a cavity used for storing liquid, a liquid discharging channel communicated with the cavity is formed in the bottom of the liquid storage container, and a liquid outlet of the liquid discharging channel is vertically downward; a test net which is arranged below the liquid outlet of the liquid storage container and can be attached to a tested drainage asphalt pavement; the test net is provided with vertical drain holes which are uniformly distributed, and a plurality of temperature sensing concentric circles which take the center of the projection of the liquid outlet of the liquid discharge channel in the vertical direction as the center of a circle and are formed by coating a temperature sensing color-changing coating. When the detection device is used for detecting the drainage coefficient of the drainage asphalt pavement, the drainage coefficient of the drainage asphalt pavement can be vividly judged and tested, and the detection range can meet thedesign index requirements of the drainage asphalt pavement. The invention also relates to a method for detecting the drainage coefficient of the drainage asphalt pavement.

Description

technical field [0001] The invention relates to the technical field of pavement detection, in particular to a detection device for detecting the drainage coefficient of a drainage asphalt pavement, and a detection method for the drainage coefficient of a drainage asphalt pavement. Background technique [0002] Drainage asphalt pavement, also known as permeable asphalt pavement, uses large-void asphalt mixture as the surface layer, penetrates rainfall into the drainage functional layer, and discharges rainwater horizontally through the layer, thereby eliminating The road surface water film that brings many adverse effects of driving can significantly improve the safety and comfort of driving in rainy days. At the same time, because the porous characteristics of drainage asphalt pavement can greatly reduce traffic noise, it is also called low-noise asphalt pavement (low-noise asphalt pavement). [0003] Drainage asphalt pavement has been widely used in road engineering due to...
