Structural Impacts Of Super Heavy Load (Shl) Vehicles On Transportation Infrastructure, Ali Morovatdar
Structural Impacts Of Super Heavy Load (Shl) Vehicles On Transportation Infrastructure, Ali Morovatdar
Open Access Theses & Dissertations
Operation of non-conventional Super Heavy Load (SHL) vehicles is an ongoing challenge for transportation stakeholders and the traveling public across the nation. Despite facilitating the movement of heavy, large, and non-divisible loads, passages of such vehicles with complex loading configurations that typically weigh several folds of the permissible weight limits set forth by regulatory agencies have been adversely affecting the structural integrity of pavement facilities. This translates into accelerated damage of pavement structures, which in turn poses safety concerns for users of the transportation facilities. Accurate quantification of such detrimental impacts is the precursor to preserve the existing transportation facilities. …
Harmonizing Asphalt Mix Selection With Pavement Structural Design, Mahdi Saghafi
Harmonizing Asphalt Mix Selection With Pavement Structural Design, Mahdi Saghafi
Open Access Theses & Dissertations
The state-of-the-practice in asphalt concrete (AC) mix design and pavement structural design are based on two divergent concepts. The laboratory tests that are used for mix design, especially under the balanced mix design concept, are pragmatically accelerated surrogate tests developed to ensure the stability or ranking of mixes. Pavement structural design methods, being empirical or mechanistic, ignore these laboratory test results, in favor of other mechanical parameters. As such, the selection of the type of mix to be placed on a project is based on the local experience, and a set of consensus limits, rather than the demand of the …
Geospatial Relationship Of Intelligent Compaction Measurement Values With In-Situ Testing For Quality Assessment Of Geomaterials, Luis Alberto Lemus
Geospatial Relationship Of Intelligent Compaction Measurement Values With In-Situ Testing For Quality Assessment Of Geomaterials, Luis Alberto Lemus
Open Access Theses & Dissertations
The implementation of Intelligent Compaction (IC) in the construction of transportation infrastructure as a tool for quality control of compacted geomaterials has attracted the attention of a number of highway agencies. Compaction quality has been conventionally assessed using density, and to a less extent, modulus-based spot measurements at selected locations along the roadway section. While spot measurements do not provide a thorough rendition of the level of compaction of the roadway, IC technology is effective in meeting full coverage requirements. IC roller measurements are accelerometer-based measurements recording machine-ground interaction assumed to be indicative of the stiffness of the compacted geomaterial. …
Understanding The Consequences And Costs Of Climate Change On Texas Pavements, Megha Sharma
Understanding The Consequences And Costs Of Climate Change On Texas Pavements, Megha Sharma
Open Access Theses & Dissertations
Over the several centuries, the global temperatures have been rising, and the rate of rising in temperature has increased significantly in the last century. The increase in temperature and precipitation can substantially influence performance life of pavements because of their continuous exposure to climate. The climate parameters like temperature and precipitation are considered in the pavement design to reflect the influence of climate factors on the performance of the pavements. Currently, designers use the historical weather patterns while designing pavements. Since the climate is changing, the estimated service life of the pavement will be reduced significantly if the historical data …
