Question - 2: For the road network and traffic in question-1, design pavement structure for road section AA and road section BB using AASHTO 1993. The material properties are shown in Figure 2.1. The following additional information are provided: Design reliability is 90%, standard deviation, So is 0.40. CBR value of subgrade is 11. Quality of drainage is good and percentage of time pavement is exposed to moisture level approaching saturation is 1-5%. Initial serviceability is 4.2 and terminal serviceability is 2.0 for both the collector and local roads. Consider the traffic opening year as 2020. E1 = 450,000 psi V₁=0.3 E2 = 40,000 psi v₂=0.35 E3 = 20,000 psi V, 0.35 V₂=0.35 Surface Base Subbase Subgrade D₁ Asphalt Layer D₂ m₂ Unbound Layer D3 m3 Unbound Layer infinite Figure 2.1: Pavement structure to be designed
