Synthesis of NCAT Low-Noise HMA Studies
The Federal Highway Administration (FHWA) sponsored a study (AU4-C2) at the National Center for Asphalt Technology (NCAT) to evaluate different low noise HMA pavement solutions. The study involved the construction and testing of 12 low noise hot-mix asphalt (HMA) pavement structures at the NCAT Test Track. Five structures comprising coarse and fine, single and double layered open graded friction course asphalt mixtures were paved on the north-tangent at the Test Track in November 2005. NCAT Report 07-02 (1) reports on the design and testing of these structures. Construction of an additional seven structures on the south tangent at the test track was completed during the reconstruction efforts undertaken for the Phase 3 experiment at the Test Track late in 2006. These structures comprised a variety of HMA mixtures including dense-graded Superpave and stone-matrix asphalt (SMA) with varying nominal maximum aggregate sizes, as well as a microsurfacing and a propriety mixture donated by East Alabama Paving, the contractor on the Test Track Phase 3 reconstruction project. NCAT Report 07-03 (2) reports on the design and testing of these south-tangent structures. The purpose of this report is to synthesize the findings previously reported to provide an overview of the study and to draw conclusions regarding the relative performance of the different low-noise HMA structures evaluated.
