What We're Doing

The City is diamond grinding a number of streets as part of the FY19 Pavement Management Program:  

  • Western Road: (6th Avenue North to end of concrete pavement)

  • 32nd Street: (Sangre Road to Western Road)

  • Main: (32nd to 11th Avenues)

Ahead of the diamond grinding, there will be some spot panel replacements

Anticipated Milestones

  •    Anticipated Date (Design): 9.11.2019

  •    Anticipated Date (Construction): 11.11.2019

  •    Anticipated Date (Completion): 1.17.2020

Benefits of the Project

Diamond grinding is a maintenance strategy that is used on older concrete streets that extends the life of the pavement before needing to be reconstructed. Also, it provides a smoother ride and reduces the impact stress on the pavement and base which also extends the pavement life. 

The cost for grinding is approximately $10 per square yard vs. $12.80 per square yard for an asphalt overlay. The expected life of the grinding is 16 to 17 years vs. 7 years for an asphalt overlay.
