摘要

Oxidation of hydrocarbon in asphalt binder leads to the production of carbon dioxide (CO_2) during the production of hot mix asphalt. The objective of this laboratory study was to investigate the effects of the asphalt additive Sasobit~®, asphalt content and mixing/placement temperature on CO_2 emissions from binder with laboratory measurements. The isolated effects of Sasobit on asphalt absorption into the aggregate were also looked at. Temperature was found to be the only statistically significant factor on emissions. This would suggest that warm mix asphalt technology, which employs the use of Sasobit in asphalt mixtures, is a very effective way of lowering the industry' s CO_2 emission impact, both directly and by the use of less energy for heating. This work predicts that greater than 30% reduction of CO_2 emissions is possible with typically used levels of Sasobit.
