Intelligent pavements through instrumentation: early results following an extreme rainfall event

The Sunshine Coast Regional Council in Australia recently upgraded a section of Sippy Downs Drive adjacent to the University of the Sunshine Coast campus in late 2012. Prior to opening, the pavement was instrumented to monitor temperature under the surface layer, strain in the surface and sub-base layer, and moisture in both layers. The instrumented section is a pilot trial to help confirm the final instrumentation setup for a wider study in the area. The traffic is expected to grow substantially as a new suburb and two major shopping centres are built over the next three years. After the opening of this section a major rainfall event occurred with approximately 500 mm of rain over three days in early February 2013. This paper will discuss the instrumentation setup, the early results of the instrumentation monitoring, and the extreme rainfall event. The intelligence provided in the longer term from the instrumented sections will help refine assumptions in the design and rehabilitation of pavements in such an environment.
