Investigation on Using SBS and Active Carbon Filler to Reduce the VOC Emission from Bituminous Materials

Abstract

Abstract:Bituminous materials are playing a vital role in pavement design and the roofing industry because of outstanding properties. Unfortunately, bituminous materials will release volatile organic compounds (VOC), making them non-environmentally friendly. Therefore, technologies that can be used to decrease the VOC emission are urgently required. In this research, the VOC emission and material behaviors were analyzed and compared to investigate the possibility of adding styrene butadiene styrene (SBS) and active carbon filler into bituminous materials to develop environmentally-friendly materials. Thermal gravimetric analysis-mass spectrometry (TG-MS) and ultraviolet-visible spectroscopy testing (UV-Vis) were employed to characterize the VOC emission process. Temperature sweep testing and frequency sweep testing were conducted to evaluate the rheological properties of bituminous materials. Research results indicated that the combined introduction of 4 wt% styrene butadiene styrene (SBS) and 4 wt% active carbon filler cannot only significantly lower the VOC emission speed and amount, but also improve the deformation resistance behavior at a higher temperature. SBS and active carbon filler can be used to reduce the VOC emission form bituminous materials.

Inhibiting effect of Layered Double Hydroxides on the emissions of volatile organic compounds from bituminous materials

“…The Residual Volatile Speed (RVS) was introduced in previous research (Cui et al, 2014a) to characterize the changing of VOC emission before and after adding emission inhibitors. The RVS is the ratio between VOC volatile speed of LDHs modified bituminous binder and that of the non-modified bituminous binder.…”

“…Research on decreasing the speed and amount of VOC emission is vital. Additives were proposed to reduce the VOC amount (Cui et al, 2014a(Cui et al, , 2014b(Cui et al, , 2015Zhang et al, 2010). Layered Double Hydroxides (LDHs) were reported as an effective UV resistant additive to modify bituminous materials with its special synthesized MgeAl double layer structures (Pang et al, 2014;Wu et al, 2012).…”

Effect of organo-montmorillonite nanoclay on VOCs inhibition of bitumen

“…But these agents may not be suitable in all bitumen applications like in roofing [4]. Some additives, like active carbon and layered double hydroxides have been introduced into bitumen to inhibit the emission of VOCs characterized due to the porosity [19][20][21].…”

“…But with respect to the increasing traffic loads, bituminous binders need to be improved. SBS modified bitumen shows good cohesion, low temperature susceptibility, excellent elasticity [1]. SBR, rubber powder, EVA were reported as excent modifier to improve the performance of bituminous materials [2].…”
