Design a flexible pavement for a four-lane divided highway in Molepolole, given the following data: 

ESALS per day per direction = 888 

Lane distribution = 85% outside lane and 15 % inside lane 

Design period = 20 years 

Traffic growth factor = 3% 

Initial serviceability = 4.2 

Terminal serviceability = 2.5 

Reliability = 90% 

Overall standard deviation = 0.45 

Effective roadbed resilient modulus = 30 MPa 

El = 300 000 psi 

E2 = 30 000 psi 

E3 = 100 000 psi 

Mr = 6000 psi
