“The performance of RAP, FRAP and other test cells did not differ significantly when it came to distress, ride quality, structural characteristics or noise and friction. RAP percentage and fractionation p gdid not greatly influence low temperature cracking and did not influence ride performance more than seasonal variation and base type. Structural performance changed little over four years and did not vary greatly between test cells.”
