About this document

Granular Subbase Layer Coefficient Guide by mazhar is a document available to read on EtoBox.

This document provides a formula to calculate the layer coefficient (a3) for a granular subbase layer in a pavement structure. The formula uses the logarithm of the modulus of subgrade reaction (Esubbase) measured in pounds-force per square inch to determine a3. It also notes that the American Association of State Highway and Transportation Officials specification from 1993 is the source.
