WebWhen rutting is of greatest concern (during an HMA pavement’s early and mid-life), a minimum value for the elastic component of the complex shear modulus is specified. Intuitively, the higher the G* value, the stiffer the asphalt binder is (able to resist deformation), and the lower the δ value, the greater the elastic portion of G* is (able ... WebSep 1, 2009 · Rutting, or permanent deformation, is known to occur in hot-mix asphalt (HMA) pavements. Higher rut rate typically occurs at pavement temperatures higher … WebMost rutting in HMA pavements is due to shear deformation of the HMA layer so long as air void content (Va) is below about 9 percent (Monismith, 2004 [1]). Further, these shear deformations are usually limited to the upper portion of the HMA layer (Figure 2). Therefore, a laboratory test that measures shear deformation in the upper HMA layer (3 ... paleton paleta
