Subgrade Rutting Criteria Overview by suparna ghosh is a document available to read on EtoBox.
Subgrade rutting occurs when all layers beneath the pavement surface, including the subgrade, become permanently deformed or depressed. The document presents criteria for evaluating subgrade rutting put forth in IRC:37-2018, including definitions for NR (the subgrade rutting life in terms of number of standard axle loads) and εV (the vertical compressive strain at the top of the subgrade). Models are provided to calculate NR for a given design traffic load based on εV, with different models for 80% and 90%
