2. Draw typical pavement deterioration curves for two types of pavements (A and B). Pavements A and B's lifespan are 20 and 40 years until they reach a failure threshold. The cost of constructing shorter life span pavement (A) is 5 million dollars per mile whereas the pavement with longer life span (B) costs 10 million dollars per mile. You have the option of using overlays to extend the life span of a pavement which may cost 1.5 million dollars per mile with expected lifetime of 10 years. When you consider total costs (assume no inflation), which pavement type would you choose?
