Question
A flexible pavement has the following class of loads during a particular hour of the day.i. 80 buses with 2-axles (each axle load of );
ii. 160 trucks with 2-axles (front and rear axle loads of and , respectively)The equivalent standard axle load repetitions for this vehicle combination as per IRC:37-2012 would be
ii. 160 trucks with 2-axles (front and rear axle loads of and , respectively)The equivalent standard axle load repetitions for this vehicle combination as per IRC:37-2012 would be
Correct answer
(A) 180
Solution
To find the equivalent standard axle load (ESAL) repetitions, we use the Fourth Power Law as per IRC:37-2012. The Equivalent Axle Load Factor (EALF) for an axle load is given by:where is the standard axle load, which is .Step 1: Calculate ESAL for buses
- There are 80 buses, each with two axles.
- Total repetitions of axle = .
- .
- .
- There are 160 trucks.
- Each truck has one front axle and one rear axle.
- Total repetitions of axle = .
- Total repetitions of axle = .
- .
- .
- .
