Thirty-six HMA mixture designs along with associated aggregates and asphalts were obtained from the TxDOT districts and HMA mixtures were prepared and compacted (using the SGC) to an air void level below that specified in the TGC mixture design. Technicians recorded the SGC compaction curves and interpolated the number of SGC

Performance Tests for Hot Mix Asphalt (HMA) Including …
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
