Abstract: Potholes are localized depressions developed in asphalt pavement. Typical pothole repair includes temporary and permanent solutions that are highly affected by detracting factors like thermal segregation, leading to inferior compaction, and poor bonding between old and new layers. To control these factors, a novel prototype Control Pothole Repair System (CPRS), suitably modified for laboratory experimentation, has been developed. The CPRS includes three core features: (a) flexible repair design, (b) multiple, motion controlled radiant heating units that operate within a 443mm by 1.50m working envelope and (c) a Short message service (SMS)/Global positioning system (GPS). The reported study relates the initial development of CPRS and trials with it. Outcomes demonstrate the importance of preheating and strict heating provisions to the boundaries of patch repairs, both affecting the strength and durability of hot asphalt repairs. The laboratory outcomes are also used to effectively calibrate a 3D finite element model of the heating process.
