Title: Time-Series Analysis of Accelerated Pavement Testing Data to Evaluate Load Transfer Efficiency
Accession Number: 01333269
Record Type: Component
Abstract: Accelerated Pavement Testing (APT) data can be defined as a combination of time-series input parameters (i.e. traffic and environmental loading) and output responses (i.e. deflection and permanent deformation data). Analysis of the APT data through time-series techniques can potentially assist in identifying the effect that input parameters have on the measured output responses. In this paper a specific time-series analysis technique (Vector Auto Regression) is used to evaluate the influence of temperature and climate on the Load Transfer Efficiency (LTE) across cracks and joints of Ultra Thin Reinforced Concrete Pavement type (UTRCP). UTRCP sections were built on two different sub-bases with the same mix design and subsequently evaluated using a Heavy Vehicle Simulator. The aim of these tests was to evaluate a low cost alternative for the upgrading of unsurfaced roads. The results obtained suggested that LTE was not a good measure of structural deterioration, while the deflection around a crack played a significant role. Water and temperature also played a significant role determining the structural life of UTRCP roads.
