Road Ready Research, R3

Road Ready Research LogoRoad Ready Research, R3, papers summarize and share information about key roadway topics. The papers meld research findings with roadway best practices in a way that is allows roadway owners to understand and implement improvement processes. R3s are meant to serve as the conduit to transfer positive research results to the roadway, saving time and money. Research Pays!

  • Roadway Reversion (PDF, 613K): Previously, low construction and maintenance costs for pavements allowed local jurisdictions to pave large portions of their roadway network. More recently, construction and maintenance costs for asphalt roadways have risen faster than inflation and, more importantly, funding. Because of this, local roadway jurisdictions are un-paving, or reverting roadways back to an engineered gravel surface. The process has been used in more than half of the states in the United States, in Canada, and in Finland. It requires proper equipment, materials, final roadway grading and full public support to be successful. This document will review current practices including some researched best practices from NDLTAP, FHWA, and other sources.
  • Pavement Preservation Terminology (PDF, 914K): Communication is critical for an agency to have a successful pavement preservation program. Often we assume that everyone we are working with understands the jargon we use. This document contains definitions for some of the treatments and measures used to establish a successful pavement preservation program. Clear communication and clearly defined terminology are keys to building a successful team.
  • Crack Seal Best Practices (PDF, 332K): Crack sealing/filling is a cost effective pavement maintenance tool that can be effectively completed by county workers or contractors. Knowing how to most effectively employ this technique is important, as failure of this product is costly, especially in low budget situations. This review includes some researched best practices from NDDOT, FHWA, and other sources.
