An Innovative Thermo-Energy Harvesting Module For Asphalt Roadway Pavement, Seyed Amid Tahami, Samer Dessouky

Data

The importance of green technologies for generating renewable energy and sustainable development is widely accepted. Road surfaces are exposed to solar radiation that generates thermal gradients and heat flow in the pavement layers. The heat stored can be harvested providing an untapped source of renewable energy. This report presents the design, construction, and assessment of an improved thermoelectric energy prototype for harvesting heat energy from roadway pavements. To accomplish this, various prototype designs were simulated using Finite Element (FE) analysis, followed by design construction and laboratory testing of the most promising prototypes to evaluate their power harvesting capabilities. The main …

Assessment Of Long-Term Performance Of Pavements Containing Warm Mix Asphalt Technologies In Louisiana, Kwadwo Ampadu Boateng

LSU Master's Theses

This study focused on the assessment of long-term performance of asphalt pavements containing warm mix asphalt technologies in Louisiana. A total of five rehabilitation projects were studied in the state of Louisiana. The study consisted of engineering desk analyses of field performance indicators, indices and the initial laboratory performance indicators measured for five rehabilitation projects.

The engineering desk study consisted of a review of literature from previous WMA technology projects done in Louisiana. Additionally, data was acquired and validated from the Louisiana Pavement Management System (PMS). Pavement performance indicators (i.e., cracking (transverse, longitudinal, and fatigue cracking), roughness, rutting, and pavement …

Quality Assessment Of Flexible Pavement Automated Cracking Data In Louisiana, Mostafiz Emtiaz

LSU Master's Theses

Pavement distress survey is the most critical and integral part of pavement management system. Transportation agencies all over the world depends on the accurate pavement distress survey to take major decisions like pavement rehabilitation or reconstruction. Pavement management at the network level requires accurate pavement distress survey to decide the allocation of budget for pavement maintenance, rehabilitation and reconstruction. This study started collected network-level cracking distress data through manual measurements on high-resolution pavement images and the results were used as the ground truth measurements to evaluate the corresponding automated distress data from the Pavement Management System database. Results showed that …
