11 The Problem : Several high profile pavement failures on interstate resurfacing projects. Only getting a few years of life before rehab/repair was needed. Finger pointing between WVDOH and Industry. Specifications vs. workmanship. Regardless of the cause, the overall program was being destroyed by the need to let additional interstate construction contracts to fix the pavement failures.
