NSFC Grant received on Bitumen VOCs Reduction

We have successfully received a NSFC Grant on bitumen VOCs reduction. The Grant title is Synthetic Ca(OH)2-incorporated Zeolite as effective VOCs sorbents and ite multi-functional effect for Asphalt materials, with a financial support of 600 thousands RMB, from 201901 to 202212.

Since 2013, Dr. Xiao and his group focused on research on bitumen VOCs. They used GC-MS, TG-MS and some other technics to charaterize the bitumen VOCs. The volatile information of components and amount can be successfully reported with their proposed methods. They also reported the possibility of design Green Bitumen with Lower VOCs, by sythesis effective VOCs absorbers.

Seven peer reviewed journal papers have been published on bitumen VOcs related topic. They are:

Award received: Fok Ying Tung Outstanding Young Teacher of Higher Education

At the begining of March, 2018, Dr. Yue Xiao has been awarded third prize for excellent results in teaching and scientific research in the 16th Fok Ying Tung Outstanding Young Teacher of Higher Education, announced by the Department of International Cooperation and Exchanges in the Ministry of Education’s Office.

This young faculty career award, Fok Ying Tung Outstanding Young Teacher of Higher Education, honors 100 people all over China, including 5 first prizes, 15 second prizes and 80 third prizes.

The Fok Ying Tung Education Foundation was co-founded by the Ministry of Education and Dr. Henry Fok Ying Tung, a well-known Hong Kong entrepreneur who donated 100 million HKD in 1986. The Young Faculty Career Award was set up to finance and reward teachers under 35 who have made outstanding achievements in teaching and research. It is presented every two years.

One other WUT (Wuhan University of Technology) teacher, Tang Haoling, from the State Key Laboratory of Advanced Technology for Materials Synthesis and Processing, received the 14th in 2014. WUT teachers have been now honored two times.

Comparative evaluation of designing asphalt treated base mixture with composite aggregate types

Abstract: This study aims at investigating the possibility of using basalt, limestone and andesite aggregates combinations in asphalt treated base mixture. Rapid developing of asphalt pavement construction results in the lack of high quality aggregates and environmental damage. Using the composite aggregates in asphalt mixtures is an effective way to solve problems of aggregate shortage and minimize the environmental depredation.

Two types of composition methods, Coarse-Fine (C-F) composition method and Coarse-Coarse (C-C) composition method, were proposed and studied. Effective density was used in the mixture design to improve the accuracy on using composite aggregate. Research results illustrate that composite aggregate will change the volumetric properties of composite asphalt mixtures. The incorporation of alkaline coarse aggregates or surface roughness coarse aggregates on the aggregate can improve the mechanical properties of asphalt treated base. Asphalt mixture with composite of basalt and limestone aggregates can significantly enhance the moisture resistance property. Changing the types of coarse aggregates will result in more variables than changing the fine aggregates types.

Keywords: Composite aggregate, Asphalt treated base, Effective density, Road performance, Asphalt mixture

Evaluation of mechanical properties and aging index of 10-year field aged asphalt materials

Abstract: Ten years’ field aged asphalt specimens have collected and being detailed studied. The aging index, viscoelastic behavior of aged binder recovered from the cored specimens, indirect tensile strength and residual fatigue life of the top layer and underneath layer were studied. Saturates, Aromatics, Resins and Asphaltenes (SARA) analysis and Fourier Transform Infrared Analysis (FTIR), viscoelastic analysis, Indirect Tensile (IDT) resilient modulus and fatigue test were performed.

Both SARA, FTIR and viscoelastic analysis indicates that traffic loading does have positive degradation influence on asphalt binder. FTIR shows that traffic loading has limited influence on the chemic changes of S=O compounds, while has positive contribution on degrading the C=C bonds and hence promotes the oxidize aging. Although surface layer can protect underneath asphalt layer from aging, 10-year field aging would introduce significant deterioration onto the underneath layer. The effective aging depth can go as deep as to the second layer. Fatigue tests illustrate that 10-year service has resulted in very weak asphalt pavement surface. Its fatigue life is very sensitive to traffic loading.
