Embodiment Construction

[0047] The invention provides a device for testing the water seepage performance of asphalt pavement, which is designed on the principle of detachable as a whole, and structurally includes a chassis part and a water tank part, which are combined when used and disassembled after use. Among them, the chassis part is made of corrosion-resistant metal material, which is located at the place to be measured on the road surface. The water tank is partially filled and placed on the chassis to realize automatic water replenishment for the chassis. By observing the drop scale of the internal liquid level of the water tank part, it is obtained after recording the time. Leakage data. Specific structure and principle reference Figure 1 to Figure 9 shown.

[0048] The chassis part includes a stainless steel chassis 100 , a rubber sealing gasket 200 and a counterweight iron ring 300 , wherein the stainless steel chassis 100 is in the shape of a disc as a whole and is machined as a whole. ...

Abstract

The invention discloses an asphalt pavement water permeability testing device and a water permeability testing method, wherein the testing device comprises a chassis part and a water tank part which are combined for use, the testing device adopts split design, the chassis part comprises a stainless steel chassis, a rubber sealing gasket and a balance weight iron ring, an overflow passage connecting the upper and lower side spaces of the stainless steel chassis is disposed at the center of the stainless steel chassis; the water tank part includes a water tank, a cover and a plug, wherein the bottom of the water tank is provided with the cover, the central portion of the cover is an easy-to-puncture portion which is opposite to a thorn portion; the top of the water tank is a conical depression and a watering hole, a transparent material window is arranged on the side wall of the water tank, and a scale ruler is arranged on the surface of the window. The testing method using the device isprovided. The chassis part and the water tank part are separated, irrigation and experimental phases are separated, and the operation is more convenient.

Description

technical field [0001] The invention relates to road engineering technology, especially a device for testing the water seepage performance of road surfaces. Background technique [0002] With the advancement of technology, more and more attention has been paid to the water seepage performance of the pavement. The reason is that the water seepage performance directly affects the skid resistance and drainage capacity of the pavement in rainy and snowy weather. [0003] Highway pavement with good drainage performance can better prevent slipping, release water tickets, suppress splashing water, and reduce the probability of accidents when driving in the rain. In asphalt pavement, the drainage performance is determined by the permeability coefficient. The existing water seepage measuring instrument adopts the static pressure measuring method. [0004] The existing asphalt pavement water seepage performance testing device includes a measuring cylinder, a water pipe, a water valv...
