Product Introduction

Road permeability coefficient testerDetailed information:

Road permeability coefficient testerSuitable for measuring the permeability coefficient of asphalt pavement using a pavement permeability meter. 2. Instruments and materials: HDS-II type pavement permeability tester.

Key Features:
The pavement water seepage tester is finely processed and has high testing accuracy. Unique water seepage area standard ring ensures accurate water seepage area, thereby making the measurement results highly accurate; The unique exhaust function makes it more convenient for the operator to use. Suitable for measuring the water permeability coefficient of asphalt mixture pavement and rolled asphalt mixture specimens, in order to test the water permeability performance of the pavement and the ratio design of asphalt mixture. This instrument is a standard product of JTGF40-2004 "Technical Specification for Construction of Asphalt Pavement on Highways", and is also a product in the special research project of the Highway Research Institute of the Ministry of Transport - Measurement Method and Index Requirements for Asphalt Pavement Seepage.
Scope of Application
This method is applicable for measuring the water permeability coefficient of rolled asphalt mixture specimens using a pavement water permeability meter to verify the mix design of asphalt mixture.
Asphalt mixture water seepage test configuration: Road seepage meter: The upper water measuring cylinder is made of transparent organic glass, with a volume of 600mL and a scale on it. There are thick markings at 100mL and 500mL. The lower part is connected to the base through a thin tube with a diameter of 10mm, and there is a switch in the middle. The measuring cylinder is connected by a bracket, with an inner diameter of 150mm and an outer diameter of 165mm below the base. The instrument is equipped with two iron rings for weighing, each weighing approximately 5kg and with an inner diameter of 160mm.
