Hossain K, Das P, Karakas A. (2018). Effect of Ultraviolet Aging on Rheological Properties of Asphalt Cement. 63rd Annual Conference of Canadian Technical Asphalt Association (CTAA). Regina, SK, Canada. Accepted.

Posted Posted in Recent Conference Papers, Recent Publications
Abstract: Age hardening of asphalt mixtures is an irreversible process, which reduces durability of flexible pavements and increase maintenance cost. In pavement structure, aging of asphalt mixture is mainly associated with changing in asphalt cement properties due to oxidation and ultraviolet (UV) radiation.… View More

Abstract: As per the five-year provincial roads plan (2017 edition), the Department of Transportation and Works of Government of Newfoundland and Labrador shifted its focus from the construction of new roads to the maintenance and rehabilitation of existing highways. With more than 270 km of road planned to be rehabilitated/upgraded in the province by 2022, appropriate strategies are needed to maintain and rehabilitate the roads.… View More

Posted Posted in Recent Journal Articles, Recent Publications
Abstract: The current practice in the construction of jointed plain concrete pavements (JPCP) in India is to lay paving quality concrete (PQC) over roller compacted concrete designated as dry lean concrete (DLC). A plastic sheet of thickness 125 microns is placed as a bond-breaking layer at the interface of DLC and PQC.… View More

Safiuddin M, Hossain K, Collins C M. (2018). Potential Applications of Self-Cleansing Nano Lotus Leaf Biomimicked Coating in Different Construction Sectors. 7th International Materials Specialty Conference, Canadian Society for Civil Engineering. Accepted.

Posted Posted in Recent Conference Papers, Recent Publications
Abstract: Lotus leaf has a nanostructure with randomly oriented cone-like protrusions (nano-mountains) and nano-valleys between nano-mountains. The nanostructured lotus leave surface possesses an extremely high water-repelling capacity due to super hydrophobic property. This is well-known as “lotus effect”. The “lotus effect” makes nano lotus leaf biomimicked coating suitable for applications in different construction sectors.… View More

Posted Posted in Recent Conference Papers, Recent Publications
Abstract: Road traffic safety and highway improvement programs are dependent on the analysis of accurate and reliable traffic accident data. In Bangladesh, significant percentage of crash fatalities occur on limited sections of major roads and highways. These sections are generally known as High Risk Roads, Hazardous Road Locations (HRLs) or Accident Prone Location or Black Spots.… View More

Posted Posted in Recent Conference Papers, Recent Publications
Abstract: In Bangladesh, the vulnerable road users (VRUs) such as pedestrians, bicyclists, motor cyclist, pedal rickshaws and users of various informal motorized and non-motorized modes are victims of massive injury due to heterogeneous traffic practice. In most of the cases, vulnerable road users are ignored from the planning of urban road network system.… View More
