I am working on a pavement rehab project, that we will be pavement planing the asphalt to a certain depth (prefer 3" th) and placing an asphalt overlay (3"). We have received cores and have found that there is a chip seal base where some locations of the asphalt overlay is only 1-1/4" thick, other locations it is thicker. Does anyone know if planing machines have issues milling the chip seal, due to the amount of binder? And if it does not have a problem with milling it, does it however, damage the remaining chip seal base? Thanks
