Evaluating The Impact Of Different Types Of Stabilized Bases On The Overall Performance Of Flexible Pavements, Andrae Anthony Francois
Evaluating The Impact Of Different Types Of Stabilized Bases On The Overall Performance Of Flexible Pavements, Andrae Anthony Francois
Theses and Dissertations
This study was initiated with the aim of evaluating the impact of stabilized and untreated base layers on the performance (i.e., fatigue and rutting) of flexible pavements. Four field sections constructed using stabilized base layers (i.e., bituminous (asphalt emulsion), calcium chloride (CaCl-2), Portland cement, and geogrid stabilized base layers) and a control section constructed using untreated RAP aggregates were analyzed in this study. Falling Weight Deflectometer (FWD) tests were conducted on all the field sections and the collected data was used to backcalculate the elastic moduli for all layers. The influence of the stabilized bases and the untreated RAP base …
Structural Strength Evaluation And Retrofitting Of Hangar Q At Millville Airport, Harshdutta Indradutta Pandya
Structural Strength Evaluation And Retrofitting Of Hangar Q At Millville Airport, Harshdutta Indradutta Pandya
Theses and Dissertations
Hangar Q was built in Millville, New Jersey as a part of the Home Defense Program of World War II. The airport is now owned and operated by the Delaware River and Bay Authority (DRBA) as the Millville Airport. Hangar Q was a historic nine-bow truss hangar when it was first constructed, standing at 30 feet high, 130 feet wide, and 160 feet deep. It was originally constructed with no side walls and no back wall or front roll-up doors. It was later updated from a completely open design to a closed design. The objective of this study was to …
Relaxation In Bolted Assemblies, Samuel Augustus Moeller
Relaxation In Bolted Assemblies, Samuel Augustus Moeller
Theses and Dissertations
The purposes of this investigation were to (a) extend previously developed elastic spring models for bolt assemblies to include simulating creep loss in the bolt and the threads and (b) to present an approach in which appropriate spring stiffness in the model are determined rationally. Previous efforts at modeling tension in bolts have been limited in that they were not readily applicable to analyses of realistic bolted connections. The simulated load distributions on the shank and the threads in a single-bolt assembly showed good comparison to the gathered experimental data as did the simulated, time dependent creep loss in the …
