Recent developments in computer technology combined with the advent of data condensation technologies have opened new ways to analyse and explore data.

This report details an exploratory use of a full set of time series rutting data from a long-term pavement performance (LTPP) site in condition calculations.

Using a full data set, as opposed to single aggregated measures, such as the mean, currently used in pavement deterioration assessments, allows practitioners to more accurately evaluate pavement condition and target maintenance.

Data condensation techniques were used, converting the data set into an HTML text string that can be stored in a single Excel cell. This allows the full data to be employed in calculations instead of a single number.

The work presented in this report challenges well-established practices and procedures. It is anticipated that these readily available new techniques will benefits the road construction and maintenance industries in many ways.
