Question No$.2-$show clear calculations.

A$.$ The front axle mass of a seven axle truck is $6$ ton. The

gross vehicle mass of this vehicle is $54$ ton. A trucking

operator overloads this vehicle to a gross vehicle mass

of $66$ ton. The tare $($empty$)$ mass of this vehicle is $24$ ton.

What is the difference in damage per $100$ ton cargo

carried for the legal and overloaded vehicle on a shallow

and on a deep pavement? Use load equivalence

exponents of $6$ and $2.$ Discuss your findings.

B$.$ A provincial roads department has opened two two$-$lane

roads with ES$3$ design traffic. At the time of opening both

roads carry the following traffic in the heaviest trafficked

lane.

Using a load equivalence Exponent of $4,$ determine after how

many years the roads will reach the design traffic for the following

scenario;

i$.$ Road A$-$There is no E$80$ growth during the life of the facility

ii$.$ Road B$-$for the first $14$ years traffic will grow at $6\%$ per year,

and then the E$80$s will reduce at $4\%.$
