abstract="Substandard utility cut restorations have many negative consequences including shortened pavement life. Several ways to solve this problem were considered including more comprehensive inspection procedures to ensure that specifications are met. The latter was dismissed in favor of the use of unshrinkable fill. A study to evaluate the pros and cons of unshrinkable fill as opposed to granular fill showed that it was the preferable alternative. The reasons for this are set forth. It is shown that in spite of some flaws, unshrinkable fill performs at least as well as granular fill in virtually all aspects. Furthermore, it has many distinct advantages, including costs, consistency, and reduced inspection requirements. It is noted that using unshrinkable fill is helpful in maintaining high quality pavement.<p />",
