New method for testing binder content
In each country, thousands of tests must be performed every year, and chlorinated carbohydrates – a range of chemicals having various carcinogenic effects – are commonly used as solvents. Initially, the most widely applied solvent was chloroform, which was later replaced by trichloroethylene. However, at Colas, we have already switched over to the application of less dangerous tetrachloroethylene.
The significance of tyre-pavement noise in road construction increases
CPX (close-proximity) measurements are carried out with a special trailer or with microphones fitted onto consoles mounted close to the tyres. The essence of the CPX method lies in the evaluation of signals recorded by microphones set up at a given distance from the vehicle’s or the trailer’s tyres.
