Sorry, I can't take non credible sources seriously, posted by someone with a one sided agenda makes them even less credible. If thats considered research these days then I guess I'd rather be "uninformed." Our state does comprehensive. Multi year testing for best practices. Road wear conditions. New products and procedures. Even though I have limited direct dealing with the townships road crew anymore, I still attend p-sats for their seminars. Actually during one of them I was quite embarrassed. It was on the modern use of road fabrics. The gentleman presenting it was part of a 10 year study on fabric uses on primary and secondary roads. At the time the township didn't use any fabrics and we have a few roads that join then next township that started using fabrics. The case study road was one that has a chicken farm, and mulch/ landscape depot on it. Sees higher thennaverage heavy truck traffic for a secondary road. During the study both roads were over layed twice, my township used standard 19.5mm, with a 6mm top. The other township used fabric then 19.5, top coated with 6mm. Second paving @5 years we did a single course of 6mm tops. Other township did another course of fabric and 6mm tops. The pictures were enough to make anyone believe the fabric tied the road together and gave better wear characteristics.
That's real research. Not something off forbs, touting the things we've learned already.
As I said, our roads were never designed for the heavy traffic, and never designed for the amount of traffic seen today. There's no real dispropotinal amount that heavy trucks pay in taxes, fees and registration vs a passenger car or light truck. And it's side stepping the issue that ev's arnt taxed in any sort of way to help with their part of the damage they cause.
