Safi F, Al-Qadi I, Hossain K, Ozer H. (2018). Total Recycled Asphalt (TRA) Mixes’ Characteristics and Field Performance. 98th Annual Conference of Transportation Research Board (TRB) of National Academies of Science and Engineering. Washington DC, USA.

Abstract: The use of recycled materials in asphalt concrete (AC) pavement has increased significantly for economic and sustainable benefits. However, the use of recycled materials can pose risks to the performance of asphalt pavements. The Illinois Department of Transportation (IDOT) has developed five distinct total recycled asphalt (TRA) mixes, containing up to 60% asphalt binder replacement (ABR) obtained from reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS); whereas 100% recycled aggregates are acquired from RAP, steel slag, and recycled concrete aggregate (RCA).… View More

Abstract: The government of India has embarked on the construction of major highways with concrete pavements to eliminate frequent maintenance of bituminous pavement, damaged by heavy commercial vehicles and moisture. It is therefore necessary to re-examine the current pavement design with a sound analytical approach.… View More

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.

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

Abstract: The City of St. John’s (Newfoundland and Labrador, Canada) has a unique climate, with excessive precipitation year-round, moderate summers and extreme winters. The pavement foundation (subgrade) in this region consists mainly of strong metamorphic rocks. As the city is located on an island and has a small population size, roads of this city experience very low volume of heavy traffic.… 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.

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

American Society of Civil Engineers (ASCE) International Conference on Highway Pavements and Airfield Technology. Philadelphia, PA, USA.

Abstract: Reclaimed Asphalt Pavements (RAP) and Recycled Asphalt Shingles (RAS) are increasingly used in asphalt concrete (AC) pavements due to their lower initial cost and potential sustainability benefits. Despite these benefits, the use of these materials poses significant challenge as the recycled binder available in these materials is highly oxidized due to aging.… View More

Abstract: Thermal cracking is one of the major distresses in flexible pavements, especially in the northern part of the U.S. and Canada. With the increasing use of recycled materials like reclaimed asphalt pavement (RAP) and recycled asphalt shingle (RAS), asphalt pavements have become more susceptible to thermal distresses.… View More

Abstract: Permanent deformation (rutting) is one of the most common distress modes in flexible pavement. Rutting performance of asphalt mixture is very susceptible to environmental and loading conditions. In this paper, effects of applied stress and temperature on the permanent deformation of unmodified and Polyethylene Terephthalate (PET) modified asphalt mixtures (0%, 0.5% and 1% of PET by weight of aggregate particles) were evaluated using dynamic creep test at different temperatures (10˚C, 25˚C and 40˚C) and stress levels (200 kPa, 300 kPa and 400 kPa).… View More

Effect of Aging and Rejuvenation on Surface Free Energy Measurements and Adhesive Property of Asphalt Binder. 97th Annual Conference of Transportation Research Board (TRB) of National Academies of Science and Engineering. Washington DC, USA.

Abstract: During aging process physio-chemical changes occur in asphalt. As a result, many serious distresses evolve in pavement. The changes occur in asphalt from aging should have deep relation with its intrinsic properties. The surface free energy is a fundamental property of a solid and liquid.… View More
