Asphalt Segregation Repair

[Roadwork]

Anyone have experience (and success) with repair of segregation in a newly placed asphalt mat, other than to remove and replace?

Give a little more info. Is it causing raveling? Is it causing bleeding (flushing in some areas)? Which end of the gradation spectrum is affected?

 

[Roadwork]

Yes, several areas with raveling...and there is traffic on it. The large stone is segregated, and the course is a single 4" lift.

...this is asphalt base (25 mm nominal)

Sounds pretty stinky. Been there, mill and fill with appropriate ACP/add chip seal. Stacking good ACP on questionable ACP is a bad idea.

Addition of 15" CRCP overlay would probably solve the raveling issues.

What does your spec say about the contractor's responsibility for substandard work?
