Abstract

Volatile organic compounds (VOCs), which are harmful to atmospheric environment and human health, will volatilize from bituminous binder in the process of production, transportation and construction. Many inhibitors were applied to reduce the VOCs emissions for designing environment friendly bituminous material.This paper investigated the possibility of using active carbon filler to reduce the VOCs emissions from bituminous materials, by means of thermogravimetry coupled with mass spectrometry (TG-MS). Eight types of emissions were studied through ion mass spectra. The influence of active carbon on VOCs was researched by ionic density and residual volatile speed. Storage stability of modified bituminous binder had been examined as well to ensure acceptable application purpose. For further consideration, the basic properties of active carbon characterized by Scanning Electron Microscope (SEM), Surface Area and Porosity Analyzer and Fourier Transform Infrared Spectroscopy (FT-IR), for better understanding of the inhibition mechanisms.Results illustrated that adding active carbon filler into bitumen would not degrade the storage stability. Active carbon filler with porous structure can significantly reduce the VOCs emissions. The inhibition effect depends on the kind of emissions and the inhibitor's adding ratio. The influence of active carbon on VOCs reduction increased with the addition ratio and the optimum adding quantity is 5 wt%, without significant reduction of road performance. High specific surface area and developed pore structure contributed to the physical adsorption between active carbon and VOCs molecules, while organic functional groups determined the selective chemical absorption of active carbon.
