Abstract: Pavement Management System (PMS) is crucial in road network assessment and rehabilitation. One of the most significant and straightforward functional performance indices used in PMS is the International Roughness Index (IRI), which generally measures the road roughness of the pavement. Sophisticated road surface profiling equipment is... More
Abstract: Most of the Departments of Transportation in North America are shifting its focus from the construction of new roads to the maintenance and rehabilitation of existing highways. Every year thousands of kilometers of road are being maintained or rehabilitated in North America. So, there is a necessity to look for appropriate strategies to... More
Abstract: There exists two factors to assist in deciding whether or not a municipality should expect to have a roadway management system, these being population size and road network size. A large population tends to contribute more vehicles to the roads, which leads to frequent maintenance needs and therefore requires a road management system.... More
Abstract: Since 2008, the number of roads in Canada has been going up due to rapid urbanization and economic growth, and by 2020, there is more than 1.08 million kilometres of roads across the country. Around 90% of roads managed in Canada are paved with asphalt materials. During the service life, asphalt pavement experiences... More

Abstract: Roadway infrastructure is a major transportation facility required for the deployment of autonomous vehicles. However, in the field of vehicle automation research, two critical questions are still unsolved: “Is the current roadway infrastructure sufficient for such highly autonomous vehicles?” and “How can the current roadway...

Abstract: Moisture damage of asphalt pavement has always been one of the major concerns for researchers in the pavement engineering field. Mitigating this moisture-induced damage is essential for improving pavement performance, extending service life, and reducing lifecycle costs. Several studies have reported that waste plastic can potentially... More
Abstract: Semirigid pavements are gaining importance in the pavement design field due to their improved performance in freezing zones. These semirigid pavements are constructed similarly to asphalt pavements, but with a cement-stabilized base layer. However, there is a limited study that quantifies the influence of design factors on the... More
Abstract: This study evaluated the relative effect of different modifiers and antistripping additives on the rheological properties of asphalt binder PG 58-28, commonly used in Newfoundland and Labrador, Canada. Four antistripping additives: ZycoTherm SP2, Kling Beta 2914, Pave Bond Lite, and AD-Here were used at different dosage rates for... More
Abstract: Structural evaluation of road networks has always been a challenge for road agencies, especially in developing countries like Iran, from both economic and operational perspectives. Many researchers have sought innovative solutions such as developing structural indices or predictive models to address this issue. However, the proposed... More
Abstract: This paper presents results of a research project completed to compare the ice-melting capabilities of environmentally friendly alternative deicers with average road salt. Tests were conducted in an environmental chamber where temperatures could be controlled to a certain degree to ensure that the test specimens were in the ideal... More
Abstract: Rising costs of constructing and maintaining asphaltic concrete pavements present a challenge requiring an alternative solution. Nanomaterials can be cost-effectively integrated with asphalt binder to provide beneficial effects for asphaltic concrete mixture. This paper investigated seven different types of nanomaterials, namely... More
Abstract: Autonomous vehicles (AVs) movement in a narrower traffic lane and anticipated climate change are crucial for asphalt concrete (AC) pavement distress. This study assesses the combined effect of AVs and climate change on the performance of AC pavement for a road section in Ontario, Canada. The performance of AC pavement due to AVs... More
