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 … Continue reading

Using Activated Carbon to Reduce the Volatile Organic Compounds from Bituminous Materials

Abstract: The objective of this research is to characterize the reduction of volatile organic compounds (VOCs) from bituminous materials resulted from activated carbon. A gas chromatography-mass spectrometer (GC-MS) was used to separate VOC components, and ultraviolet-visible spectrophotometry (UV-Vis) was conducted … Continue reading

Study of the Diffusion of Rejuvenators and Its Effect on Aged Bitumen Binder

Abstract: Aged asphalt mixture is heavily involved in pavement maintenance and renewed construction because of the development of recycling techniques. The aged bitumen binder has partially lost its viscous behavior. Rejuvenators are therefore designed and used in this recycling procedure … Continue reading
