Rheological And Chemical Characteristics Of Asphalt Binders Recycled Using Recycling Agents And Nanoparticles, Mohamadtaqi Baqersad

FIU Electronic Theses and Dissertations

The reuse and recycling of materials, especially materials derived from nature, is necessary for a sustainable environment and world. Asphalt mixture is a combination of asphalt binder and aggregates, both of which originated from nature. The reuse and recycling of aged asphalt materials (RAP) is widespread. However, a large portion of these materials is wasted. One primary reason for the reluctance to use a high percentage of RAP in recycled asphalt is uncertainty in the long-term performance of recycled asphalt pavement. To improve the long-term performance of recycled asphalt, new additives and Recycling Agents (RA) are used to modify the …

Robust Maximum Flow Network Interdiction Problem, Darshan Rajesh Chauhan

Dissertations and Theses

In this thesis, a maximum flow-based network interdiction problem considering uncertainties in arc capacities and interdiction resource consumption is solved. The problem consists of two entities with opposing objectives: the goal of the adversary is to maximize the flow of illicit drugs through the network, while the goal of the interdictor is to minimize the maximum flow by completely interdicting arcs given a specified amount of resources. Lack of complete information about the usage patterns of the transportation network by the adversary results in an uncertain estimate of arc capacity and resources required for interdiction by the interdictor. To account …
