Ahmed R B, Hossain K, Hajj R M. (2020). Chemical, Morphological, and Fundamental Behavior of Rejuvenated Asphalt Binders. ASCE Journal of Materials in Civil Engineering. https://doi.org/10.1061/(ASCE)MT.1943-5533.0003564

Abstract: This study investigates the chemical characteristics of rejuvenators and the effect of different rejuvenators on the morphology and fundamental behavior of rejuvenated asphalt binders.  Gas Chromatography-Mass Spectroscopy (GC-MS) and atomic force microscopy (AFM) were conducted to determine the chemical composition of rejuvenators and asphalt surfaces’ morphology.… View More

Alam R, Hossain K, Bazan C. (2020). A Systematic Approach to Estimate Global Warming Potential from Pavement Vehicle Interaction Using Canadian Long-Term Pavement Performance Data. Journal of Cleaner Production. Elsevier. https://doi.org/10.1016/j.jclepro.2020.123106

Abstract: Pavement vehicle interaction (PVI) is one of the significant components in the use phase of pavement life cycle assessment. This component has attribution with excess fuel consumption, resulting in an increase in the global warming potential (GWP). Several research have been conducted to model and quantify the PVI effect based on pavement roughness and deflection.… View More

Reza A, Hossain K, Dhar A. (2020). Compressibility Assessment of Roadway Embankments Using Tire Derived Aggregates (TDA). Canadian Society for Civil Engineering (CSCE) Annual Conference. Saskatoon, Canada.

Abstract: On average, one tire per capita per year is generated in Canada as a waste tire which either goes to landfill or stockpile. Researchers across the world are trying alternative use of scrap tires. Among many civil engineering applications, roadway embankment construction using tire derived aggregates (TDA) is the most popular and ecologically viable due to large amount of consumption of material in the embankment.… View More

Ahmed R B, Hossain K. (2020). Characterization of Rejuvenated Asphalt Binders Using FTIR and AFM Techniques. RILEM International Symposium on Bituminous Materials. Lyon, France.

Abstract: This study investigates the chemical and morphological behavior of rejuvenated asphalt binders. A TFOT aged PG 58-28 binder was mixed with three different types of rejuvenators that include waste cooking oil/ untreated used cooking oil (UT), treated used oil (TR), and Hydrolene (HL) at 3%, 6% and 9% by the weight of the total binder.… View More

Ahmed R B, Hossain K, Aurilio M. (2019). Characterization of Asphalt Rheology Using Waste Cooking Oil as a Rejuvenator. Journal of Construction and Building Materials. Under Review.

Abstract: This study investigates the performance of aged binders blended with three different types of rejuvenators. The thin film oven test (TFOT) aged PG 58-28 binder was mixed with raw waste cooking oil (R1), modified waste cooking oil (R2), and Hydrolene H90T (R3) at the concentrations of 3%, 6%, and 9% respectively determined by the weight of the total binder.… View More

Khan S, Nagabhushana M N, Hossain K, Tiwari D. (2020). Investigation of Pavement Responses Using Multi-Depth Deflectometer. 99th Annual Meeting of the Transportation Research Board (TRB) of National Academies of Science and Engineering. Washington DC, USA.

Abstract: Load associated cracking and permanent deformations are the common distress found on flexible pavements. Rutting is one of the major failure mechanisms in flexible pavement. The present study focuses on the measurement of rutting using Accelerated Pavement Testing Facility. For the measurement of rutting, the pavement was instrumented with a Multi-Depth Deflectometer (MDD) to measure the interfacial layer deflections for determining permanent deformation of each layer.… View More

Ahmed R B, Hossain K, Aurilio M. (2019). Rheological Characterization of Rejuvenated Asphalt Binders. 99th Annual Meeting of the Transportation Research Board (TRB) of National Academies of Science and Engineering. Washington DC, USA.

Abstract: Using reclaimed asphalt pavement (RAP) material in pavement construction is an environmentally friendly practice. However, the asphalt available in recycled pavements is already oxidized and stiffened due to various environmental processes. As a result, using RAP binder in cold regions like Canada can have a significant negative effect on pavement performance and may accelerate the pavement distresses especially thermal cracking along with the alteration of rheological properties.… View More

Rana M, Swarna S T, Hossain K. (2020). Climate Change Impact on Pavement Performance in Newfoundland, Canada. 99th Annual Meeting of the Transportation Research Board (TRB) of National Academies of Science and Engineering. Washington DC, USA.

Abstract: In recent years climate change has become a threat to both the existing and upcoming pavement infrastructure. Most of the researchers agree that the climate change started affecting the existing pavement infrastructure all over the world. Therefore, there is a need for changing the design procedure by considering the climate change.… View More
