Comparison of Conventional and Advanced Pavement Design Methods with Ontario Case Studies
(University of Waterloo, 2020-12-14)Many methods have been used to effectively design a pavement structure that carries the required traffic loads. In Canada, American Association of State Highway and Transportation Officials 93 (AASHTO 93), Shell Pavement ... -
Developing Cost-Effective Pavement Maintenance and Rehabilitation Schedules: Application of MEPDG-Based Distress Models and Key Performance Index
(University of Waterloo, 2017-04-26)Pavement Maintenance and Rehabilitation (M&R) are the most critical and expensive components of infrastructure asset management. Increasing traffic load, climate change and resource limitations for road maintenance accelerate ... -
Development of a Framework to Evaluate Asphalt Binder and Plant Produced Asphalt Mixes for Acceptance in Canada
(University of Waterloo, 2022-05-05)Asphalt binder, sometimes referred to as asphalt cement binder, or asphalt cement, is the binder that holds the aggregates together in asphalt mixes for asphalt concrete pavements. In Canada, asphalt binder properties are ... -
Development of a New and Innovative Concrete Paver
(University of Waterloo, 2021-07-22)Interlocking Concrete pavers (ICPs) have become increasingly common in North America. These pavements consist of impermeable concrete paving units and permeable joints that allow water to freely enter the surface. The ... -
Development of CPATT Database and Quality Control Checks for Concrete Pavement Field Data
(University of Waterloo, 2022-01-10)Abstract The Centre for Pavement and Transportation Technology (CPATT) located at the University of Waterloo, Canada, has robust research capabilities. This is largely related to a team of researchers who have conducted ... -
Development of Empirical and Mechanistic Empirical Performance models at Project and Network levels
(University of Waterloo, 2016-08-02)Performance prediction models are a vital component in pavement management systems (PMS). Along with decision trees, prediction models are used to set priorities for maintenance and rehabilitation planning, and ultimately ... -
Development of Machine Learning Based Analytical Tools for Pavement Performance Assessment and Crack Detection
(University of Waterloo, 2019-08-19)Pavement Management System (PMS) analytical tools mainly consist of pavement condition investigation and evaluation tools, pavement condition rating and assessment tools, pavement performance prediction tools, treatment ... -
Development of Performance-Related Specifications for Asphalt Mixtures in Ontario
(University of Waterloo, 2021-08-25)Superpave mix design relying on volumetric specifications is not completely able to predict the long-term performance of asphalt pavements. Therefore, implementation of suitable performance specifications is crucial to ... -
Engineering and Environmental Assessment of Foam Glass Lightweight Aggregate for Pavement Application
(University of Waterloo, 2019-04-02)Foam-Glass Lightweight Aggregate (FG-LWA) is an innovative lightweight material based 95% on waste and recycled glass. Several European countries use this type of material in the pavement structure and mainly as lightweight ... -
An Enhanced Mechanistic Analysis Framework for Designing Resilient Airfield Pavements
(University of Waterloo, 2023-01-05)Changes in climatic conditions can directly impact pavement performance. With alarming temperature records and the increased frequency of extreme weather events, Canadian infrastructure could be at risk if adaptation ... -
Evaluating Support Conditions for Precast Concrete Inlay Panels using Finite Element Analysis
(University of Waterloo, 2019-08-12)Precast concrete inlay panels (PCIPs) are a unique application of precast concrete pavement used for overnight rehabilitations of high-traffic volume asphalt highways exhibiting structural rutting issues. The pavement is ... -
Evaluating the Confinement Effect to Improve Gravel Runway Performance
(University of Waterloo, 2019-04-23)This research was intended to adapt an existing strength testing method used only in Russia for conformance with Aircraft Flight Manuals typical of North America. Bearing strength requirements are typically listed by minimum ... -
Evaluating Thermal Regime of Cold Region Roads for Climate Change Adaptation
(University of Waterloo, 2020-04-07)Nearly a quarter of the Northern Hemisphere is underlain with permafrost, of which discontinuous permafrost is most sensitive to the temperature of its surrounding. Climate change and the implementation of infrastructure ... -
Evaluating Unbonded Concrete Overlay for Usage on Ontario Residential Streets
(University of Waterloo, 2018-01-22)Composite pavements have become increasingly common in North America, these pavements usually result from the rehabilitation of Portland cement concrete (PCC) pavements. When a PCC pavement reaches close to the end of its ... -
