Research and Validation of Neoloy® Tough-Cells' Unique Modulus Improvement Factor (MIF)

Significant research based on field, lab and numerical analyses, by Rajagopal (et al) an internationally recognized leader in the field of geotechnical engineering, and Kief (et al) an expert geotechnical engineer, has verified that the MIF (Modulus Improvement Factor) is a reliable method for quantifying the Neoloy (NPA - Novel Polymeric Alloy) Tough-Cell contribution to pavement structures, and can be used in design methodology for all types of road, rail and heavy pavements, particularly on expansive clay soils.
