Still the same - the cancelled flights are mostly between 3 and 6 pm.
@Marc in CA et al: The cancelled flights are "American Eagle" regional flights, operated by Mesa Airlines, which uses
only CRJ regional jets and thus has no other type to substitute.
American can't be pulling larger jets out of their own schedule to cover for the contractor.

I doubt soft asphalt plays any role - KPHX is all concrete, so far as the airline ramps, taxiways, and runways are concerned.
