Comparative Performance Of Rubberized Hot Mix Asphalt Under Alf Loading, Hanlin Qin
Comparative Performance Of Rubberized Hot Mix Asphalt Under Alf Loading, Hanlin Qin
Doctoral Dissertations
In response to the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991, Louisiana constructed five projects to evaluate several methods of using discarded tire rubber in highway pavements. The field performance was quite variable. To achieve the agreement among state agencies on the engineering benefits of using crumb rubber modifier (CRM) in HMA pavement and to define the circumstances where the LaDOTD can use asphalt rubber materials in the most cost effective way, a full-scale research program has been conducted at the Louisiana Transportation Research Center (LTRC) to evaluate the performance of CRM-HMA asphalt pavement under Accelerated Loading Facilities (ALF). …
Decision Analysis With Value-Focused Thinking As A Methodology In Structuring The Civil Engineer Operations Flight, Dee Jay Katzer
Decision Analysis With Value-Focused Thinking As A Methodology In Structuring The Civil Engineer Operations Flight, Dee Jay Katzer
Theses and Dissertations
The civil engineer operations flight organizational structure has been in a state of change since the flight's inception and is currently prescribed only to the element level. Therefore, an operations flight commander must determine the organizational structure best suited for their unique situation without any guidance or support. To provide insight and defensible support for an operations flight commander faced with this decision, a value-focused thinking process was used to create a value model that aids in evaluating possible organizational structures. To ensure that the results of this research are applicable across the Air Force, the value model was created …
Evaluation Of Civil Engineering Operations Flight Competitive Sourcing Standards And Metrics, Ty A. Randall
Evaluation Of Civil Engineering Operations Flight Competitive Sourcing Standards And Metrics, Ty A. Randall
Theses and Dissertations
The Performance Work Statement (PWS), which defines the requirements and shapes the outcome of the activity under contract, and the Quality Assurance Surveillance Plan (QASP), which is vital in identifying what is to be evaluated, become critical documents as the Air Force enters into more competitive sourcing contracts. Currently, contractors and Most Efficient Organizations (MEO) are evaluated by the QASP based upon the requirements found in the PWS. It is imperative the PWS and QASP documents have adequate performance metrics and that they are applied appropriately to evaluate the contractor or MEO. This research collected PWS and QASP documents from …
