A Novel Control Pothole Repair System Using Radiant Heat for Long Lasting Patch Repairs

Typical hot pothole repairs include temporary and permanent solutions that are highly affected by detracting factors such as poor interface bonding between host pavement and hot fill material. This based in their different mass temperatures. To address the issue a novel prototype Control Pothole Repair System (CPRS) that preheats the excavated pothole prior to its repair is suggested. The CPRS includes a number of innovative features including multiple motion controlled radiant heaters and positioning information. Current practices have used heating for removal of defected material and ensuring that surface temperature of fill pothole is sufficiently high. The authors believe that only doing the above is not in itself a sufficient measure for ensuring bonding with introduced fill. This holds that it is necessary to preheat the excavated pothole prior to its repair. The reported study relates the initial development of CPRS, its heating capabilities and pothole excavation preheating by it. All the experiments are laboratory based executed to a single size pothole this constituting initial stages of a wider research being developed by the authors towards longer lasting pothole repairs. Outcomes demonstrate temperature distribution below and on the heater plate, pothole preheating with consideration of cooling influences and significant temperature differentials between pothole excavation base and boundaries. The latter suggests weakness in common hot pothole repair practice. The laboratory outcomes are used to effectively calibrate a three dimensional finite element thermal model of the pothole heating process, this intended to be part of a future control algorithm for the heater.
