Abstract

This report presents the findings of a research project to validate the gyration levels in the N-design table (Table 1) in AASHTO R 35 by following the behavior under traffic of a series of field projects. Its main finding is that, based on ultimate pavement densities achieved on 40 field projects in 16 states across the United States, modest reductions in N-design are possible. Such reductions, if adopted, should lead to hot mix asphalt (HMA) mix designs that are http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_573.pdfmore readily compacted in the field. The report will be of particular interest to materials engineers in state highway agencies, as well as to materials suppliers and paving contractor personnel responsible for the specification, design, and production of HMA.
