Since 2013, Dr. Xiao is deeply involved in Research on Volatile Organic Compounds (VOCs) Characterization and Design Bituminous Materials with Lower VOC emissions. Here is a list of his Journal Publications on VOC topic. Furthermore, Dr. Xiao gave an oral presentation in TRC conference in the title of Design Bituminous Materials with Lower VOC Emissions.

Paper 1 first introduced test methods including TG-MS and UV-Vis that can be used to characterize VOCs. VOC reduction resulted from active carbon filler and SBS were studied by means of Ion current intensity, residual volatile speed and UV-Vis calibration curve. The rheological behaviors were also presented in this paper.
Paper No.2 discussed the degradation changes after VOC emission process. Weight reduction, phase angle, complex shear modulus and master curves were presented. LDHs influence on basic properties of bitumen were investigated as well.
UV-VIS was the only one method that used in Paper 3. UV-Vis calibration curve was included in this paper. Total amount reduction of SBS, C and LDHs were presented.
Paper 4 and 5 discussed the possibility of using LDHs to reduce VOCs. Test methods including TG and TG-MS were employed to reduction behavior. Ion current intensity of multi molecules were investigated. Residual volatile speed was studied as well.
During June 6-8, Dr. Yue attended the first Transportation Research Congress (TRC) that was held in the National Convention Center in Beijing. TRC is jointly organized by universities, research institutes, industries, and China Highway and Transportation Society. It aims at providing an international platform for incubating, leading, demonstrating and implementing innovations, and ultimately evolves into a think tank for transportation innovations. Researchers on the construction and building materials from all of the world joined this conference.
It was very proud for Dr. Yue to get an opportunity to give a presentation in TRC conference. His presentation title was Design Bituminous Materials with Lower VOC Emissions. This presentation focus on presenting the research results by using activated carbon and layered double hydroxides to reduce the VOC emissions from bituminous materials.

Rubber-like Quasi-thermosetting Polyetheramine-cured Epoxy Asphalt Composites Capable of Being Opened to Traffic Immediately, fide it on nature.com.
Abstract: This paper reports the facile preparation, mechanical performance and linear viscoelasticity of polyetheramine-cured rubber-like epoxy asphalt composites (EACs) with different asphalt contents. Compared with previous EACs prepared via complex chemical reactions and time-consuming high-temperature curing, the EACs reported here were obtained by using a compatible, bi-functional polyetheramine and a simple physical co-blend process, which make the EACs feasibly scalable for production at a lower cost. The EACs were cured for 1 h at 160 °C and 3 d at 60 °C; therefore, these composites can be opened to traffic immediately. The EACs have a much greater temperature stability than common thermoplastic polymer-modified asphalt composites from −30 °C to 120 °C, but their complex shear moduli at higher temperatures slightly decrease instead of remaining constant when temperatures are greater than 80 °C, especially for the higher asphalt content composites; that is, these composites are quasi-thermosetting. Wicket plots illustrate that the EACs reported here are thermorheological simple materials, and the master curves are constructed and well-fitted by generalized logistic sigmoidal model functions. This research provides a facile, low-cost method for the preparation of polyetheramine-cured EACs that can be opened to traffic immediately, and the concept of quasi-thermosetting may facilitate the development of cheaper EACs for advanced applications.

Abstract: The effect of Layered Double Hydroxides (LDHs) additives as VOC emission inhibitor for bituminous materials was studied in this research. Ion histogram of volatile compounds from bituminous material was obtained by means of Thermogravimetry-Mass Spectrometry analysis. Results obtained for the pure bitumen and LDHs-modified bitumen show that LDHs modifier has the potential to reduce the volatile speed and amount of VOC emissions. The reduction effect varies on different molecules or compounds. The reduction effect on volatile speed is significant with smaller molecules. The effect of LDHs on the volatile speed of more carcinogenic volatile compounds shows that the reduction in speed is significantly bigger on dichloroethane and naphthalene than that on normal octane. The study findings indicate that four percent of LDHs is an optimum in achieving the best emission reduction of VOC for the investigated bituminous material.
