The EV₂ Test is required to assess the in-situ stiffness, load-bearing capacity, and compaction quality of pavement foundation layers. It provides a direct measure of the elastic deformation behavior of the soil or granular layer under load, which cannot be accurately determined by density-based tests alone. The test ensures that the prepared layer has adequate structural strength to support traffic loads and prevents premature pavement failures such as rutting and settlement.

Where the EV₂ Test Is Used

The EV₂ Test is conducted on:

• Subgradesoil / Subsoil / Groundsoil
• Granular Sub-Base (GSB)
• Wet Mix Macadam (WMM) / Base layers / Blanket layer
• Formation level before pavement construction
• Rehabilitated pavement layers prior to overlay works

It is commonly used in Railway, Highway, Expressway, Airport, and Industrial Pavement Projects as a Quality Control and acceptance test to verify compliance with design and specification requirements.
