HOW TO ACHIEVE

Safe, Smooth, Quiet and Affordable

PAVEMENTS IN ARIZONA

Arizonans face increasing pavement maintenance needs.

What can be done to fix Arizona's highways?

Takeaway Thoughts

  • Concrete pavement was and is the preferred surface solution. Diamond grinding makes it quiet. Diamond grinding requires $3.9 billion less tax dollars (over 30 years), is cooler, more sustainable, and provides longer-lasting service when compared to asphalt rubber.

 

  • Concrete pavements can be smooth and quiet. Diamond grinding provides the smoothest and quietest concrete surface available.

  • ​​Citizens were never afforded the opportunity to compare diamond grinding to asphalt rubber when a political decision was made to use rubber. But you can experience it today and make your own decision!

  • Arizona Department of Transportation's original engineering investigation into roadway noise resulted in their recommending concrete surfaces. The investigation also accurately predicted the increase in asphalt rubber noise levels over time.

 

  • User delays: diamond grinding would only be done once during a 30-year time frame, while the entire highway would have to have asphalt rubber removed and replaced twice during this period. In addition, periodic maintenance of asphalt rubber would occur in between. These activities cause traffic congestion, accidents, and loss of commuter time. 

  • The recently diamond-ground Price Road 101 section now has 20-25% more capacity than the section with asphalt rubber and generates the same or less noise.

  • ​Concrete roads are constructed from local materials by local tradespeople.
