Purpose:

The instrument is designed and made as per T0613 “Asphalt Breaking Point Test (Fraass Methods) in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine Fraass Breaking Point of bituminous materials.

The instrument can make determination for 3 pieces of samples at the same time, and calculate the average value of three test data. The instrument uses computer to control cooling rate and the instrument is equipped with a printer to print out test data and a RS232 output port.
