The flexible pavement cross-section shown in Figure 2 was determined by the Asphalt Institute method. The HMA and Type II ETB thicknesses are 4 in. and 14 in. respectively. Calculate the overall AASHTO pavement structural number. The pavement in Figure 2 is designed for the same conditions (traffic, design life, soil type, etc.) as the pavement in Figure 1. Is the overall structural number comparable to the overall structural number from Problem 4? HMA a1=0.44

The flexible pavement cross-section shown in Figure 2 was determined by the
Asphalt Institute method. The HMA and Type II ETB thicknesses are 4 in. and 14 in.
respectively. Calculate the overall AASHTO pavement structural number. The
pavement in Figure 2 is designed for the same conditions (traffic, design life, soil
type, etc.) as the pavement in Figure 1. Is the overall structural number comparable
to the overall structural number from Problem 4?
