RE: Warm Mix Asphalt
According to some discussions I have been in the middle of, problem areas would be:
Improper mixing and inadequate compaction
I would be on the lookout for segregation behind the lay down equipment and making sure compaction is quickly obtained. When the mix cools sufficiently, the mix reportedly gets hard, real fast.

RE: Warm Mix Asphalt
We've used it and have had some success and some issue with it thus far. There are several factors to consider. Plant calibration, RAP usage, cost (reduced energy yes, but new costs more always)....watch paver speed. Think that caused one of our problems last year.
