Cost-Effective Rut Repair Methods
Wheelpath rutting prevents rapid drainage of water from the pavement surface and causes hydroplaning. Deeply rutted pavements are associated with driver fatigue, vehicle steering problems, and vehicle wear. This report reviews state-of-the-practice methods for repairing rutted asphalt concrete pavements. Information sources included technical literature, paving industry representatives and highway agency personnel. The report describes methods for repairing ruts, but does not address all rutting mechanisms. It covers tire-abrasion rutting and plastic deformation of asphalt concrete. Rutting from deformation of unbound layers is not addressed. Reasons for targeting specific rut damage types are explained. The report presents: (1) Concepts regarding selection of rut-resistant materials; (2) Descriptions of materials and construction methods for five repair methods (Micro-Surfacing; Ultra-Thin Bonded Wearing Course-NovaChip(Reg); Ultra-Thin Bonded Wearing Course-Ultra-Thin Whitetopping; Stone Matrix Asphalt; and Conventional Overlays Using High Quality Mixes and Materials); (3) Basic cost estimates and discussions of important economic principals involved in selecting one of the repair types; and (4) Extensive references separated as to both past and current rut repair research. Recommendations support constructing experimental sections for evaluating the performance of each rut repair method in Alaska, followed by large-scale trials of viable methods.
