Which Performance Grade asphalt binder would work best in resisting low temperature cracks and which would work best in preventing rutting? a) 58-22 b) 60-20 c) 80-35 d) 82-33
An agency uses the following formula to determine pavement condition rating, PCR = 99.3 − 5.51 (5.0-ROUGH) − 1.59 LNALL − 0.221 AVGOUT − 0.0306 LONG − 0.531 TRAN, where we have the following. ROUGH = roughness measured by present serviceability rating (PSR), scale of 0 to 5 LNALL = natural logarithm of alligator cracking, ft per mile AVGOUT = outer wheel path rutting (all locations averaged), 0.01 inch LONG = longitudinal cracking, ft per mile TRAN = transverse cracking, number of cracks per mile And, present serviceability rating is determined as the following. PSR = 5e−0.0051118 · IRI − 0.0016027 A pavement section has the following distress data. IRI = 108 in./mi Alligator cracking = 110 ft/mi Average rutting = 0.20 in. Longitudinal cracks = 130 ft/mi Transverse cracks = 12/mi Determine the current PCR for this section. PCR = Now, assume a new roughness measurement is expected soon. When PCR falls below 60, the section will be scheduled for rehabilitation. Determine the new IRI…
