30 year roadway life? Hmm, we must be doing something wrong, because we're getting more like 70 We use more than just rejuvinators; we rate our roads and curb/gutter annualy based on PCI/CCI (Pavement/Curb condition index). We have a detailed pavment deteroriation curve based on our pavement sections and our local conditions, including climate, subgrade, etc. We specifiy different mixes, different binders, different joint sealers and compaction tests depending on the roadway and expected traffic. We count cars to make sure we know which mix to use. We stay up on current training and industry standards, we have on site inspection and testing. I agree that rejuvinators are not a cure-all. In my (semi) profesional opinion, they are the best solution for newer asphalt drives. They are not a cure-all, I would not use them exclusivley, they are just another tool in the pavement maintence box that can be used to get the design life (30 years) and then some from a pavement section.
