A-Core Concrete Specialists recently helped Arizona Department of Transportation with exploring another option for smoothing out the ride along Phoenix-area freeways where the asphalt pavement showed its age and was wearing down, especially after last winter’s heavier wet weather.
The Arizona Department of Transportation is evaluating sections where diamond grinding was done as part of a recent pavement repair and preservation project.
Crews last month removed a 1-inch layer of rubberized asphalt that was worn out by time, traffic and Mother Nature.
“This is another tool in our pavement-improvement tool box,” said Randy Everett, senior administrator of ADOT’s Central Construction and Maintenance District serving the Phoenix area. “This is an opportunity to explore options and see how the diamond grind performs in an area where the rubberized asphalt finally wore down well after its expected lifespan of 10 years.”
