RLPD Test Results 45 5.3 RLPD Data Envelopes After removing all outliers, a qualitative measure was taken to compare the permanent deformation performance of each mix type, primary stabilizing agent, and chemical additive. RLPD envelopes were defined by the greatest and least deformation curves for each mix combination.
