Asphalt mixture indentation penetration tester

Asphalt mixture indentation penetration tester

This instrument is used to test the penetration of asphalt mixture. It is mainly used to conduct penetration tests on asphalt mixture used for bridge paving, in order to determine its temperature and load at a certain temperature

Deformation under load capacity. Penetration tests can be conducted on a single specimen, or parallel penetration tests can be conducted on two specimens simultaneously, and the heating of circulating water can be set
