Asphalt permeability has a direct impact on the performance and longevity of pavements. Long-term internal exposure to water and water vapor in the asphalt voids is a significant factor in the premature deterioration of roadways.

Asphalt Bitumen Mixture Permeability Tester

Model:LQJHB-1

I.Product Introduction

The asphalt mixture permeability meter conforms to DL/T5362-2006 hydraulic asphalt concrete test specification to measure the permeability coefficient of asphalt concrete.The constant head test is suitable for the specimens with larger permeability coefficient,and the variable head test is suitable for the specimens with smaller permeability coefficient.Furthermore,the design and testing principles of this equipment also reference the relevant requirements of ASTM D4867/D4867M“Standard Test Method for Effect of Moisture on Asphalt Mixtures,”enhancing the international applicability and comparability of its test results.
