摘要: The US Route 30 bypass of Wooster, Ohio, in Wayne County, WAY-30, was constructed to demonstrate two types of extended service pavements, a long-life Portland cement concrete (PCC) pavement on the eastbound lanes and an asphalt concrete (AC) perpetual pavement on the westbound lanes. Both pavements are designed to provide 50 years or more of service with minimal maintenance (e.g. resurfacing). The PCC pavement structure features a thick and extra-wide slab on an asphalt treated base, while the AC pavement structure features a Superpave surface and a Fatigue Resistant Layer (FRL). Report FHWA/OH-2008/7 discusses the instrumentation and studies of the response of the pavement under loads. For this study, samples of all pavement materials, including soils, granular subbase material, PCC mixes, and AC mixes were tested in the laboratory to determine material parameters. Four asphalt mixes were selected to provide a rut and fatigue resistant pavement structure, while two mixes of the PCC were used in different sections of the road.
