"Phase Change Materials as Temperature Regulators in Asphalt Pavement"


By
Daniela Betancourt Jimenez
Purdue MSE Ph.D. Preliminary Exam

Advisor: Professor Carlos J. Martinez



ABSTRACT


Asphalt pavement constitute the building material for approximately 95% of the roads in the United States. However, due to the viscoelastic nature of the binder, the performance of the asphalt can be dramatically affected by extreme temperatures. The integration of phase change materials (PCMs) has been proven to be a feasible and effective way to regulate the temperature in other building materials and it's currently being investigated for asphalt applications. This report summarizes the main approaches studied for the incorporation of PCM systems in asphalt pavement materials and some of the challenges encountered in the process. It also proposes the use of a new technique for PCM microencapsulation that is believed will help overcome the problems associated with PCM encapsulation such as supercooling, low thermal conductivity and PCM leaking.  It is believed that this new method will provide a viable solution to reduce asphalt distresses and delay the ice formation and snow accumulation during the winter season.
