Life Cycle Risk Assessment Applied to Gaseous Emissions from Crumb Rubber Asphalt Pavement Construction

Asphalt mixtures for road pavements are produced and laid at high temperatures, producing gaseous emissions that contain polycyclic aromatic hydrocarbons volatile organic compounds paving workers exposed to. This paper aims to combine the effects of on human health with life cycle impacts wearing courses. The results sanitary-environmental risk analysis assessment were combined in an integrated approach, analysis, evaluate environmental performance local cancer toxicological workers. Two asphalt modified crumb rubber (CR) from end-of-life tires (gap dense graded) compared standard, unmodified mix. Air samples collected screed driver’s seat a paver during construction full-scale trial section Turin, Italy. CR course higher binder content (gap-graded) had effect 3.5 2.9 times than mixture lower percentage (dense-graded) standard mixture, respectively. Instead, 1.3 1.2 gap-graded dense-graded mix,
