Patent abstract
In methods of preparing asphalt and elastomeric polymer compositions, it has been discovered that for a given crosslinker or vulcanizing agent there is an optimum crosslinking temperature to give a composition that has top and bottom softening points that are close. That is, rubber/asphalt compatibility is improved, where the crosslinking is performed within the optimum temperature range.
