JTJ052 Specifications and Test Methods of Bitumen and BituminousMixtures for Highway Engineering.

DSHD-2806E Asphalt Softening Point Tester is applied to determine the softening point of asphalt, tar, liquid asphalt and other types of asphalt. The instrument is the best choice of

asphalt manufacturers, highway and bridge construction companies,  college and universities, and research and development departments.

DSHD-2806E Asphalt Softening Point Tester adopts microcomputer controlling technology, linear heating and automatic stirring working mode.

The instrument can determine two samples at the same time and show test results automatically.

It is convenient, efficient, and reliable and is the desired instrument for laboratory to determine the softening point of asphalt.
