The scope of this work is to carry out a study to comprehensively research and evaluate effective and durable approaches to the repair/restoration of utility cuts in asphalt and Portland cement concrete pavements (PCCPs). The scope of research will not be limited to the United States; indeed, it is of interest to the FHWA to explore what other countries are doing in this subject area. This study will document, assess and determine the efficacy of repair/restoration of pavements in the context of cuts to access buried utilities or other subsurface facilities.  Particular emphasis will be placed on urban conditions where utility cuts occur frequently and the desire is to minimize their impact on both the highway agency infrastructure and the traveling public.

Goals:

The objective of this research project is to gather, analyze, and distill domestic and international information on pavement repair/restoration resulting from utility/subsurface cuts and excavations.  The research effort will focus on proven effective and novel, non-conventional and experimental techniques, with the scope of the investigation extended beyond North American practices.  The analysis will document  the effectiveness of each practice, and make recommendations on techniques roadway agencies and utility companies should employ.  Emphasis will be placed on urban applications.
