Constant head Permeability Laboratory Test Apparatus for Porous Asphalt Pavements

摘要

Drainage asphalt pavement has been recently activated to reduce traffic accidents caused by rainwater and to reduce road noise. The present invention is capable of grasping the permeability of drainage asphalt pavement in the laboratory, and it is possible to obtain the permeability coefficient of the specimen made of asphalt mixture in the mold, and to use the specimen produced from the core or the test chamber taken from the pavement. It is a device that can calculate the permeability coefficient.;Equipment that can be tested on the permeability of the existing variable has the disadvantage that the package should be laid in a wide size, it was not possible to determine the permeability coefficient before the construction of the package. This equipment is an improved hydrostatic permeability test equipment for asphalt mixture, it is possible to simply measure the permeability coefficient indoors before asphalt pavement.;Permeability coefficient, drainage asphalt mixture, indoor permeability test, hydrostatic pressure, porosity
