This asphalt rotational viscometer manufacturing is according to standard of “ASTM D4402 and BIS 73 and “SH/T-0793-2003” asphalt Brandt rotational viscometer test standards, Using rotary process to test the apparent viscosity of asphalt road in the temperature range above 45 ℃, by milli-Pascal seconds (MPa. s).
According to the measurement results, we can find out the recommended mixing and compaction construction temperatures. Compared with similar products, with high accuracy, stable viscosity value display, easy to read, easy to operate, good anti-jamming performance advantages.Specially used to measrue apparent viscosity of the asphalt road. Also used to measure the viscosity of hot melt adhesive, wax, polymer and other fluids.
