Fracture Characterization of Polymer Modified Mixes for Applications in Diverse Climatic Region
Although cracking resistance research has been carried out extensively in other states, a large amount of the work is not immediately applicable to Arizona, where the climate is substantially more extreme both in heat and in cold than many other parts of the country.

Reflective Cracking Model for Airport Asphalt Overlay Design
Reflective cracking in hot-mix asphalt (HMA) laid over existing jointed concrete airfield and highway pavements is considered as a major pavement distress. Reflective cracking mechanisms are complex due to intertwined effects of temperature and vehicular loading conditions causing intensified stresses in overlays.

Modeling the Effect of Cool Pavements on Urban Heat Island
Pavements and roofs play an essential role in shaping the urban microclimate, affecting energy balance, and contributing to the so-called Urban Heat Island (UHI) effect. UHIs phenomenon appears to be one of the main contributing causes for the increase in Building Energy Demand (BED) and adverse health conditions.

Advancing Knowledge in Cracking Resistance of Fiber-reinforced Asphalt Concrete (FRAC)
Fiber reinforcement is considered to improve the cracking resistance of asphalt concrete (AC). Fibers can delay the crack propagation and improve fracture resistance through various crack bridging mechanisms.

Impact of Automated and Connected Trucks (Platoons) on Pavement Deterioration Mechanisms
Automation technology offers numerous advantages to the trucking industry in terms of fuel savings, operational efficiencies and preventing fatal crashes.
