Development & Application Of The Transportation Index For Sustainable Places (Tisp), Jason Zheng

Master's Theses

The purpose of transportation systems go beyond the movement of people and goods. These systems shape the natural and built environment which subsequently affects social and economic interactions. However, conventional metrics typically only address the mobility aspect of transportation via measures such as level of service and congestion. Metrics are needed to evaluate the broader impacts of transportation.

This work describes the Transportation Index for Sustainable Places (TISP), a performance metric designed to assess the sustainability of transportation systems with respect to environmental, social, and economic outcomes. The development of the TISP was guided through literature review focused on understanding …

Seismic Characterization Of Recycled Aggregate Concrete, Amin Jamali

Dissertations

There are significant environmental benefits of recycling waste concrete and reusing it as aggregate for structural concrete, but the use of Recycled Aggregate Concrete (RAC) is yet limited to non-structural applications such as road sub-base. Widespread application of RAC in areas such as seismic design requires an improved knowledge of RAC behavior under multiaxial state of stresses.

The main objective of this research is the characterization of seismic properties of RAC by developing a stress-strain model which can reasonably describe the behavior under both unconfined and confined conditions. An extensive experimental program, including testing of several plain RAC cylinders as …

A Multicriteria Based Quantitative Framework For Assessing Sustainability Of Pile Foundations, Aditi Misra

Master's Theses

ABSTRACT

Civil Engineering is the major instrument of anthropocentric development over centuries through ever expanding infrastructure, cities and facilities.  Civil engineering processes are both resource and fuel intensive.  The building industry alone, during the construction stage, uses about 30-40% of the total resources used in the industrialized countries.  There is a growing consensus that delivering a sustainable built environment starts with incorporating sustainability thoughts at the planning and design stages of a project.  Geotechnical engineering is most resource intensive although this intensive consumption of energy goes unnoticed mainly because of the indirect nature of the energy used in the …

Use Of Steel Slag In Subgrade Applications, Irem Zeynep Yildirim, Monica Prezzi

JTRP Technical Reports

Steel slag is a by-product of steelmaking and refining processes. In 2006, 10-15 million metric ton of steel slag was generated in the U.S. Out of the total steel slag produced in the U.S. every year, about 50-70% is used as aggregate for road and pavement construction and approximately 15-40% is stockpiled in steel plants and eventually landfilled at slag disposal sites. Since current levels of steel slag stockpiling and landfilling are not sustainable, alternative geotechnical engineering applications for steel slag are being explored to alleviate the slag disposal problem and to help save dwindling natural resources. The main objectives …

Requirements Of A Sustainable Pavement Management System For Tanzania, N. K.M. Mushule

Tanzania Journal of Engineering and Technology (TJET)

Since the introduction of pavement management concepts in mid-1960s, more than three decades ago, a considerable number of Pavement Management Systems (PMS) have been developed and implemented widely in many parts of the world. These systems differ in scope and sophistication. However, in some cases, pavement management systems have fallen into marginal use, if not into complete disuse, because of a number of reasons. One of the major reasons leading to the marginalisation or abandonment of pavement management systems, is the failure of system developers to recognise specific and unique needs of the agency or authority responsible for road management. …
