Asphalt Segregation Repair

Asphalt Segregation Repair

Asphalt Segregation Repair

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

RE: Asphalt Segregation Repair

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?  

RE: Asphalt Segregation Repair

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

RE: Asphalt Segregation Repair

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

RE: Asphalt Segregation Repair

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.

RE: Asphalt Segregation Repair

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