The invention provides an asphalt pavement water flow experiment device, which comprises a locking nut, a guide hole and a grip, wherein the inner bottom position of a bottom frame is welded with a connecting seat with a cavity structure; a top frame has a rectangular side frame structure; and a pressing piece is in threaded match on the connecting seat. In use, a tested asphalt pavement sample isplaced in a drip frame, clear water is poured, a water seepage condition is observed, the pressing piece can thus be operated, the pressing piece presses the sample pavement, the drip condition in the case of pressing is watched, and as the pressing seat can slide horizontally, multiple parts on the sample pavement can be pressed, multiple pressure bearing water seepage observation points are formed, the water seepage condition in a regional section of the sample pavement can be observed, and the test observation performance is better. Besides, a water receiving seat arranged at the bottom ofthe device is internally provided with multiple cavities, each cavity is provided with an observation plate in a step trend in a tilting manner, the dripping clear water flows to the step section ofthe corresponding observation plate when the sample pavement falls, and the flow effects are more obvious and more intuitive.
Description
technical field [0001] The invention belongs to the technical field of the structure of an asphalt pavement material testing device, and more particularly, particularly relates to an asphalt pavement water flow experiment device. Background technique [0002] Drainage asphalt pavement, also known as porous asphalt pavement, refers to a new type of asphalt concrete surface layer with a void ratio of about 20% after compaction, which can form drainage channels inside the mixture. Its essence is a single particle size. In the field of production or teaching, a series of simulation experimental devices will be set up to sample and test the asphalt pavement laid during the construction of the project to observe The use of the water flow velocity of the laid asphalt pavement to observe the water seepage speed of the road green pavement. [0003] Based on the above description, it is found that the existing asphalt pavement water seepage test devices are mostly located at a certai...
