Question

Accepted Answer

A 2/4 lane road section consists of multiple layers including subgrade, subbase, base, and surface. It has a camber in superelevation on both sides and requires filter media. The SBC in foundation depends on the soil type and location.

A 2/4 lane road section typically consists of subgrade, subbase, base, and surface layers.
The camber in superelevation on both sides helps to provide a smooth transition for vehicles traveling at high speeds.
Filter media is used to prevent the subgrade from becoming clogged with fine particles.
The SBC in foundation depends on the soil type and location, and can range from 100 kPa to 500 kPa or more.
