Characterization of Fresh and Hardened Properties of 3D Printable Cementitious Materials Produced with Ground-Granulated Blast-Furnace Slag
(University of Waterloo, 2021-09-24)Application of additive manufacturing technology to promote the digital construction practice in civil engineering has been gaining momentum, especially during the past 5 years. To this end, three dimensionalconcrete ... -
DEVELOPMENT OF HIGH MODULUS ASPHALT CONCRETE MIX DESIGN TECHNOLOGY FOR USE ON ONTARIO’S HIGHWAYS
(University of Waterloo, 2019-01-07)Asphalt pavement is subjected to external loads including mechanical loading induced by traffic and thermal loading induced by thermal variations. The last decades have witnessed a significant rise in number of heavy ... -
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 ... -
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 ... -
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 ... -
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 ... -
Sustainable Alternative Materials in Unbound Granular Layers of Pavement Structures
(University of Waterloo, 2017-05-02)In Part 1 of this thesis, reclaimed cement concrete (commonly referred to as recycled concrete aggregate or RCA) and reclaimed asphalt pavement (RAP) are investigated as potential alternative construction materials for ... -
Towards an Optimized Laboratory Procedure for Accelerated Long-Term Oxidative Aging of Asphalt Mix Specimens
(University of Waterloo, 2018-11-14)Pavement infrastructure forms one of the most important mode of passenger and freight transportation and trade between Canada and the United States, and plays an important role in national economy as a measure of Canada’s ...
