This testing instrument is finely crafted and has high testing accuracy. It is suitable for determining the seepage coefficient of asphalt mixture pavements and asphalt mixture specimens formed by compaction. It is used to test the seepage performance of pavements and the mix design of asphalt mixtures.

Asphalt pavement permeability meter

Model:LQJHF-1

I.Product Introduction

The new standard pavement permeability meter mainly follows the"Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering"JTG 3410-2025.This method is applicable to determining the permeability coefficient of asphalt mixture specimens to verify the mix design of asphalt mixtures.During the test,the display shows the liquid level and permeability coefficient in real time.This instrument adopts a semi-automatic design,which monitors water level changes in real time through a liquid level sensor and automatically calculates the permeability coefficient,eliminating the need for manual reading and calculation,thus significantly improving testing efficiency.
