Swarna S T, Hossain K, Reddy M A, Pandey B B. (2018). A Mechanistic and Economic Analysis of Two-Lift Concrete Pavements. Road Materials and Pavement Design. Under Review

Posted Posted in Recent Journal Articles, Recent Publications
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: Coal-based thermal power plants all over the world face serious problems of handling and disposal of the ash produced. The high ash content (30–50%) of the coal in India makes this problem complex. At present, about 145 thermal power stations in India produce nearly 184 million(quantity) tonnes of coal ash per annum (CEA,2015).… View More

Abstract: More than 95 % of road network in India is made up of flexible pavement, especially due to the relative lesser initial cost, ease of construction and maintenance. The design of flexible pavement in India is done with criteria of load associated fatigue cracking and permanent deformation (rutting).… View More

Abstract: The Indian Road Network is the second largest in the world after U.S. and flexible pavement is the most sought pavement in India. In fact, majority of roads in India (more then 90 %) are flexible pavement due to ease of construction and initial cost of construction.… View More

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: 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

Posted Posted in Recent Journal Articles, Recent Publications
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
