HOW RECYCLING FITS NEVADA'S PAVEMENT PROGRAM

A task force in Nevada came up with three sweeping recommendations to change the state prevention strategy to a pro-active one. First, the state will prioritize projects based on how quickly they are deteriorating or prediction models, not on the basis of their current condition. Second prevention strategies should be ranked by life-cycle cost, not initial cost. And third, the DOT needed to spend more on pavement preservation initially to optimize the program by reducing the backlog. The department spent about $4 million less on pavement preservation on average per year over the next six years and reduced its backlog by 50% to $263 million. One strategy that helped was relying on cold-in-place recycling, which it deployed based on a sophisticated lifecycle cost comparison, which is described. It optimized its projects by assigning roads to five categories based on volume and environmental conditions. One attraction of cold-in-place recycling is that the pavement's performance life is about the same as overlay's, though it does perform better in milder climates. Adjusting by adding lime has caused improvements in harsh conditions.
