Occupational health risk assessment for the workers exposed to rubberized asphalt fumes

The incremental health risk for workers of the road-paving sector using rubberized asphalt was assessed based on the outcome of monitoring campaigns carried out during paving operations where both rubberized and standard asphalt were used. The exposure of workers to Polycyclic Aromatic Hydrocarbons (PAHs) released in the asphalt fumes were measured by means of personal samplers and dermal sampling pads, followed by laboratory analysis. Based on monitoring data, the incremental cancer resulted significantly lower for rubberized asphalt in comparison with standard asphalt. The laboratory measurement of PAH released by the 2 asphalt mixtures to understand the cause of the observed difference and the PAH emission potential of rubberized and standard asphalt mixtures is undergoing.
