According to pavement performance tests this paper analyzes six HMA mixes which gradations are BRZ, CRZ, TRZ, HRZ, ARZ and AC-16 by Chinese Specification respectively. The restricted zone may not be necessary to follow every performance when all other relevant requirements of Superpave design are requested. HMA mix's pavement performance is optimal when the gradation is through the restricted zone.269316 bytesapplication/pdfenUniversity of PretoriaTransportRestricted zonePavement performanceHMA mixTransportation -- CongressesPavements -- China -- Quality controlPavement performanceEvent
