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

Abstract: Over 90% of the paved roads in Canada are asphalt pavements. Most of the pavements were built decades ago and are currently exhibiting a significant amount of surface distresses. These distresses include potholes, rutting (deformation in the wheel path), and cracking.… 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

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

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

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
