Equivalency of Crushed Rock with Industrial By-Products and Geosynthetic-Reinforced Aggregates Used for Working Platforms During Pavement Construction

A study was conducted to define an equivalency criterion for five materials used for working platforms during pavement construction on a poor subgrade: conventional crushed rock (referred to as null run) and four alternatives [i.e. null 2 granular backfill (referred to as Grade 2), foundry slag, bottom ash, and foundry sand]. Total deflection data for the equivalency assessment were obtained from a large-scale model experiment (LSME) simulating...
