Lower temperatures - the best for asphalt, bitumen, environment and health and safety

A number of new technologies have been developed that allows asphalt mixtures to be produced and placed at significantly lower temperatures. The reduction in temperature leads to energy savings and a reduction of CO2 production, less wear on mixing equipment and less ageing of the bitumen, an important reduction in emissions. The German BITUMEN Forum examined the toxicological data of these additives and measured the exposure to emissions on the construction sites. The use of modified rolled asphalt at temperatures of about 125-135degreesC reduced emission exposure by up to 50%. With modified mastic asphalt, the processing temperature could be reduced from 235-250degreesC to approx. 210-225degreesC reducing emissions exposure by more than 80% for some tasks.
