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?

Transcribed Image Text: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?
Expert Solution
Step 1
Given:-
The lifespan of the pavement A = 20 years
The lifespan of the pavement B = 40 years
The cost of constructing pavement A = 5 million dollars per mile
The cost of constructing pavement B = 10 million dollars per mile
The cost of overlaying = 1.5 million dollars per mile
The expectation in lifespan = 10 years
To determine:-
While considering total costs, the type of pavement should be chosen
