National Research Council Strategic Highway Research Project Finds Perma-Patch Best in Durability through Multiple Tests
The cost most commonly associated with pothole patching is the cost of purchasing material. This is usually one of the least significant contributors to the overall cost of patching operations. However, the material used for patching does impact the cost of the overall operation when there are differences in performance. More expensive materials that are placed with little effort, yet yield long-term durability, can reduce the cost of the initial patching effort, as well as the amount of re-patching needed. This reduces the labor and equipment costs for the overall operation.
