Summary:
No cracking appeared during the first year of service.  During the second year, cracking began to appear.  The asphalt-
rubber sections show approximately 1/3 of the reflective cracking of the control section.  Wheelpath rutting, while
insignificant, is less in the asphalt-rubber sections than in the control.  Frictional resistance of the asphalt-rubber
sections is approximately 12% higher than the control.
