The Marshall stability tester is a laboratory device specifically designed for testing the performance of asphalt mixtures. It determines the maximum compressive strength (stability) and deformation (flow value) of specimens using standard loading methods.

Marshall stability tester

Model:LQ-DF002

I.Product Introduction

This instrument is designed and manufactured according to the relevant requirements of T0709-2025"Marshall Stability Test of Asphalt Mixtures"in the"Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering"(JTG 3410-2025),and references international standards such as ASTM D5581-25,ASTM D6927-22,AASHTO T245,BS 598-107,and EN 12697-34:2021.The equipment is suitable for Marshall stability testing of asphalt mixtures,accurately determining the failure point of asphalt mixtures for mix design or quality inspection of asphalt pavement construction.
