Evaluating WMA design per R 35 requires the usual volumetric testing plus evaluations of coating, compactability, moisture sensitivity, and rutting resistance. The best answer reflects the full set of tests required to ensure both proper density and long-term performance: volumetric testing provides the essential density and air voids control, coating checks ensure binder coverage and adhesion to the aggregate, compactability shows how readily the mix achieves target density in practice, moisture sensitivity screens for potential moisture-induced damage like stripping, and rutting resistance measures the mix’s resistance to permanent deformation under traffic. Because this combination covers all the mandated evaluations, it is the complete choice, whereas the other options miss one or more critical assessments.
