Less than six months after placement, several thousand locations of rapid set cementitious concrete patching material had failed at the Reno “spaghetti bowl.” Nevada Department of Transportation materials engineers were tasked with finding an improved material that would provide significant longevity compared to the cementitious materials registered on the State’s Qualified Products List. The 7000 failures had occurred using a QPL material.
A project was put out to bid calling for replacement of all failed patches, requiring the use of PPC Easy Patch Plus. The low bid was submitted by the “same contractor” that had placed the failed material in the previous year. This posed an interesting problem, did they just need a more user friendly material, or had the contractor screwed up? The contractor was, more or less, directed to purchase Kwik Bond’s PPC Easy Patch Plus. At that point in time, another failed patching material was not an option.
Traffic control restrictions were in effect so the work would have to be performed at night under strict time limitations. Temperatures varied from low 40°s to 50° F. The PPC Easy Patch system would be required to cure very rapidly, handle heavy loads, and last a long time. The expectations for PPC Easy Patch were very high. The work was performed without incedent, and the road was always opened on time.
After six years (and counting) NDOT reports the PPC Easy Patches to be performing with over 99% success. There is no other patching material matching this level of performance.
