Static And Dynamic Properties Of Controlled Low-Strength Materials Incorporating Treated Oil Sands Waste, Ahmed Mneina
Static And Dynamic Properties Of Controlled Low-Strength Materials Incorporating Treated Oil Sands Waste, Ahmed Mneina
Electronic Thesis and Dissertation Repository
Controlled Low-Strength Materials (CLSM) is a self-compacted self-leveling cementitious material with compressive strength of 8.3 MPa or less. It is used as an alternative of soil backfill materials in geotechnical and infrastructure applications. This study investigates the effects of incorporating treated oil sand wastes (TOSW) as a partial replacement of sand or fly ash on fresh and hardened properties of CLSM. In addition, the environmental impact of the proposed new mixtures was evaluated. The results show that CLSM mixtures incorporating TOSW had satisfied the limits and requirements of ACI committee 229 for CLSM with no environmental hazards. The incorporation of …
Structural Competency And Environmental Soundness Of The Recycled Base Materials In North Texas, Mohammad Faysal
Structural Competency And Environmental Soundness Of The Recycled Base Materials In North Texas, Mohammad Faysal
Civil Engineering Dissertations
Aggregates, which are derived from natural resources, are the most important raw materials used in pavement construction; however, depletion of the natural resources, increasing labor costs, and environmental concerns have led us to look for alternatives. Recycled materials, such as recycled crushed concrete aggregate (RCCA) and reclaimed asphalt pavement (RAP), can be used as an alternative to natural aggregates and can be obtained from construction of newer structures and demolition of existing structures, such as buildings, bridges, pavement, etc. Recycled materials can reduce the cost, depletion of natural resources, and construction debris. The properties of recycled materials are source-dependent, which …

A Tool To Evaluate Sustainability Of Pavement Maintenance Projects., Yibo Zhang
Electronic Theses and Dissertations
Pavement maintenance activities are widely regarded to be critical elements during pavement life cycle, different maintenance techniques have been used to restore or extend the service lives of pavements. However, the existing maintenance practices on pavement system have problems that impair the economic benefits, disturb the natural environment, and somewhat ignore the needs from stakeholders. To minimize these negative impacts, sustainability is an ideal way because it addresses the problems under Triple Bottom Line (TBL, refers to economy, environment, and society). Sustainability analysis within transportation or pavement industry has been studied in different countries, but the concept of sustainable pavement …
Life Cycle Assessment (Lca) Of Ore Transportation Route Alternatives For Eagle Mine, Soumith Kumar Oduru
Life Cycle Assessment (Lca) Of Ore Transportation Route Alternatives For Eagle Mine, Soumith Kumar Oduru
Dissertations, Master's Theses and Master's Reports
Transportation sector at large is a major consumer of fossil fuels and constitutes more than a quarter of the global greenhouse gas emissions. When making infrastructure route and mode choice decisions for new freight-oriented projects, it is important that environmental and emissions considerations are included as an integral part of the selection process. Emissions from freight transportation projects related to mining and natural resource industry are especially critical, as they involve high volumes and tonnages often in pristine environments. The most logical time for emissions analysis is during modal and route analysis that are often conducted in the planning stage …
