Guidance for the selection of pothole repair options

Abstract

Potholes are a major problem in many parts of the world. The approach to the repair of these defects is varied because they occur on different types of road and their causes can be very different. As a result, many different techniques and products are offered for the repair of potholes, all of which have advantages and disadvantages. The relative effectiveness of the different techniques and products can vary from site to site. This paper describes a Scottish study that aims to provide a consistent approach to selecting a pothole repair material or technique from treatments currently available. The new guidance is based on consultation with a range of practitioners from Scottish road authorities involved in repairing potholes. The resulting discussions and information gathering led to the development of ideas for the selection process outlined in the guide. A simple procedure utilising flowcharts has been developed to assist users to identify an appropriate pothole material or technique to treat potholes located in different situations. Whilst it is impossible to identify the unique "best" option for each situation, it is intended that the guidance will lead to the most appropriate option being selected.

“…The discussions and information gathering described above, led to the development of ideas for a selection procedure and guide [2]. It was highlighted that many different techniques and products are offered for the repair of potholes, and they all have advantages and disadvantages dependent on the location of the defect.…”
