PG-58S-28 215-310 Degrees (COLD)
PG-64S-22 220-320 Degrees (Non-Heavy)
PG-64E-22 240-330 Degrees (Heavy)
Rutting Reduced with the proper BINDER grade and Asphalt content.
May have been caused by allowing traffic on a map that was too hot.
Need for a scratch course, leveling, or milling
Scratch Course: used to fill wheel ruts & other local small depressions
Leveling Course: used to provide a relatively uniform level platform for placing
binder or wearing course.
