This asphalt mixture and aggregate density tester is a specialized testing device that uses vacuum sealing technology to accurately determine the density and specific gravity of asphalt mixtures and aggregates.

Automatic vacuum sealing device for asphalt mixture

Model:LQ-HJ001

I. Product Introduction

The LQ-HJ001 Automatic Vacuum Sealing Tester for Asphalt Mixtures is a high-precision testing device specifically designed for asphalt mixture specimens with a water absorption rate greater than 2%. It is used to determine the bulk relative density, bulk density, and interconnected porosity of the specimens. The device achieves a reliable seal by automatically drawing a vacuum, ensuring a tight fit between the specimen and the sealing bag. This effectively avoids testing errors caused by moisture entering the specimen, as is common in traditional methods, thus ensuring the accuracy and repeatability of the test results.

This instrument complies with the latest industry standards and meets the following international standards:

ASTM D6752/D6752M-25

ASTM D6857/D6857M-25

AASHTO T 331

The equipment is stable, easy to operate, and particularly suitable for export to international markets with stringent testing standards.
