  5. 321 changes • Owner/Agency distinction • Compaction issues addressed • Self directed target changes for producers • Void and binder content requirements • Sample frequency depending on project size

  6. 337 Crack sealing specification • Brand new section • Most popular products included • Application very easy to understand

  7. 325, 717 Asphalt rubber • Application is in 325 • Binder is in 717 • Both section now reflect current “state of the art” practices

  8. MAG 2012 Asphalt Working group

  9. Asphalt Working Group 2012 major case revisions: • 332 protection of uncured surfaces • 317 dust control for milling • 711 Asphalt Binder spec. added binders, typos • 710 added low traffic gyratory spec. • 709,710 use of RAP

  10. Thank you! • This work and all of the cases are done by industry, City engineers, County engineers, MAG engineers.
