Question

A flexible pavement is subjected to the following loadings

• 100 commercial vehicles with 2-axles with each axle load subjected to standard axle load of 80 kN
• 150 commercial vehicles with 2-axles with each axle load subjected to axle load of 60 kN,

The equivalent standard axle load repetitions for this vehicle combination is ______ . (Rounded upto two decimal places)

Answer 1

Standard axle load = 80 kN
$ESAL=(2\times 100\times {\left(\frac{80}{80}\right)}^4)+(2\times 150\times {\left(\frac{60}{80}\right)}^4)=294.92$
