Generally hill profiles are irregular. So, the most efficient method for hill road is the prismoidal method (Simpson method). It based on the assumption that profile is parabolic between two sections. For use of this method, it is necessary that profile should be divided into odd number of section.Read more
Generally hill profiles are irregular. So, the most efficient method for hill road is the prismoidal method (Simpson method). It based on the assumption that profile is parabolic between two sections.
For use of this method, it is necessary that profile should be divided into odd number of section. If the profile is divided in even number of section than apply prismoidal method till the second last section and apply the trapezoidal method in last section.
