Flexible pavement in rural interstate highway. Design ESAL 3000000 Subbase exposed to moisture saturation 5% of time & drainage quality is fair. Base saturation level 10% of time (Fair drainage quality). Mr (HMA) 420,000 psi Mr (base) 24,000 psi Mr (subbase) 10,000 psi CBR (Subgrade) = 1.0 Reliability Level R = 85% So 0.45 APSI = 2 Required: 1) Design the pavement by the AASHTO method 2) If the total traffic reaches double, what is the percent of the slab thickness increased
