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 ... -
Enhancing Real-Time Data Acquisition from Embedded Road Structural Health Monitoring Systems
(University of Waterloo, 2024-04-23)Canada's economy heavily relies on its roadways, yet managing pavement assets faces challenges due to past infrastructure spending cuts. Addressing this, a pavement management system (PMS) is essential for efficient resource ... -
Evaluating the Effect of a Self-Healing Elastomer on the Self-Healing Properties of Asphalt Cement
(University of Waterloo, 2020-09-25)Asphalt pavements exhibit an interesting behaviour when the traffic loading is removed. The chemical structure of asphalt cement lends itself to the ability to heal damage and improve the longevity of the pavement. This ... -
Experimental Investigation and ANN Modelling of the Behavior of Asphalt Binders Modified with Novel Geopolymers
(University of Waterloo, 2022-08-24)The design of asphalt pavement has an impact on a country’s economic and environmental development. The main factors limiting the service life of flexible pavements are severe weather and increasing traffic volumes. Rutting ... -
Fatigue Characterization of Asphalt Mixes with Polymer Modified Asphalt Cement
(University of Waterloo, 2018-11-14)Asphalt pavement cracking is the most prevalent distress in pavements. In flexible pavements, fatigue cracking is a major cause of deterioration and can significantly reduce the service life of pavements [1]. Fatigue ... -
Full-Depth Reclamation with Hydraulic Road Binders
(University of Waterloo, 2020-01-20)According to a recent report, 16.4% of Canadian roads are in a poor or very poor condition. This means 146,255 km of the Canadian roads are either unfit for service or are approaching the end of their service life. The ... -
Hydraulic Road Binder (HRB) and Its Use for Subgrade Stabilization in Ontario, Canada
(University of Waterloo, 2019-12-18)The term “subgrade” refers to the in-situ material composed of natural soil located underneath the pavement structural layers. The quality of natural subgrade is highly influenced by soil type, moisture content, and organic ... -
Improving Durability of Asphalt Mixes Produced With Reclaimed Asphalt Pavement (RAP) by Enhancing Binder Blending
(University of Waterloo, 2019-04-30)Reclaimed Asphalt Pavement (RAP) has been favoured over virgin materials in the light of the unstable cost of virgin asphalt binders, shortage of quality aggregates, and compelling need to preserve the environment and ... -
Investigating and Developing Fatigue-Healing Characterization of Asphalt Materials
(University of Waterloo, 2023-04-25)Canada’s aging highway network, consisting of over 1.1 million kilometres of roads, is a vital component in ensuring the safe and reliable day-to-day movement of people and goods. Flexible asphalt pavements experience ... -
Investigating Solutions for Self-Healing and Crack Mitigation of Flexible Pavement Materials
(University of Waterloo, 2023-01-23)In Canada, cracking is the most common deterioration mode of flexible pavements that occurs for different reasons such as traffic loading, and low temperature. Moreover, the propagation of cracks can be accelerated by the ... -
Investigation of Different Factors Affecting Asphalt Cement Ageing and Durability
(University of Waterloo, 2019-08-21)Asphalt cement is an organic material and, like any other organic material tends to react with atmospheric oxygen, thus changing its physical properties (more accurately rheological properties) gradually over time. Although ... -
