An eight-lane divided highway is to be constructed with flexible pavement. Traffic volume forecasts indicate that the average annual daily traffic (AADT) in both directions during the first year of operation will be 12,000 with the following vehicle mix and axle loads. Passenger cars (1000 lb/axle) 50% 2-axle single-unit trucks (6000 lb/axle) 33% 3-axle singlet trailer trucks (10,000 lb/axle) 17% The vehicle mix is expected to remain the same throughout the design life of the pavement. If the expected annual traffic growth rate is 4% for all vehicles, determine the design ESAL, given a design period of 20 years. The percent of traffic on the design lane is 45%, and the pavement has a terminal serviceability index (p) of 2.5 and SN of 5.

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 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 = 106 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 = 0.531 TRAN, 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 value (in in./mi)…
