Temperature Monitoring in Construction Materials

Asphalt

In the production of asphalt, the viscosity of asphalt cement varies with temperature. The quality of asphalt is graded based on ranges of consistency at a standard temperature.

Application Need 

Asphalt is very temperature sensitive. When produced at the plant, if it is too hot, it oxidizes and becomes too viscous. If the asphalt is too cold, it is hard to spread at the job site. Asphalt plants need to measure the temperature of asphalt as it is loaded into the truck, to ensure that the asphalt mix has not cooled off too much in the storage silo.
