Purpose:
The instrument is designed and made as per the National Standard GB/T4507 “Test Methods for Softening Point of Asphalt” and T0606 “Asphalt Softening Point Test (Ring and Ball Methods)” in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine softening point of petroleum asphalt, coal pitch, liquid petroleum asphalt, and other asphalts.
Computer control, linearity heating, and automatic stirring, the instrument can determine two samples at the same time and show test data automatically after tests. It is convenient, efficient, and reliable. It is the desired instrument to determine softening point of asphalt for laboratory.
