SMARTROAD
Brief
Description:
The Virginia SMARTROAD is a 5.7-mile,
limited-access highway of which the first 2 miles is designated as a controlled
pavement test facility. The road has two lanes in each direction, and a 3.0m
shoulder on each side. Provisions exist to route traffic around controlled test
zones to allow for ongoing testing. The pavement research plan provides for
testing of various hypotheses on pavement material performance and
characteristics, all pavement layers are instrumented for monitoring loading and
the environment. The simulation of different types of weather conditions is
possible. An underground conduit network provides on-site data acquisition The
pavement test road includes 12 flexible pavement test sections and a
continuously reinforced rigid pavement. The sensor array includes strain gages,
pressure cells, thermocouples, time-domain reflectometry (TDR) probes, and
resistivity probes. Some unique measurements in this facility include measuring
strain in the aggregate layer, pressure underneath the hot-mix asphalt (HMA)
layer and direct measurements of moisture.
