used to "bump" up to a stiffer asphalt to minimize rutting and shoving potential on high ESAL and high volume roads with slow moving traffic. The asphalt binder grades now used with MSCR are PG 58x -28 and PG 58x - 34. With MSCR grading the bumping is done through the selection of a letter after the high temperature grade (the 58x).
