Description
Technical Parameters
Summary
The instrument is designed and made as per the national standard of People’s Republic of China GB/T4507 Standard Test Method for Softening Point of Asphalt and T0606 Asphalt Softening Point Test (Ring and Ball Methods) in the industrial standard of People’s Republic of China JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the softening point of asphalt, tar, liquid asphalt and other types of asphalt. It is the best choice of asphalt manufacturers, highway and bridge construction companies, college and universities, and research and development departments.
It adopts microcomputer control technology, linear heating and automatic stirring working mode, it can determine two samples at a time and can show test result automatically. It is convenient, efficient, and reliable. It is the desired instrument for laboratory to determine the softening point of asphalt.
