Find Sections

Find Sections (a.k.a. Section Filters) provides filter criteria to narrow down the selection of LTPP test sections. Users can apply filters from multiple classifications at their discretion. Selected Section Count is updated in real-time as the user applies filters.

Analysis Ready Datasets

A new data feature called “Analysis-Ready Datasets” provides users with integrated data in a more consistent format that is directly available to download. The primary goal of this new data feature is to assist users with assembling data needed for pavement design and performance modelling by reducing the data wrangling effort.

The Analysis Ready Materials Dataset (ARMAD) is the first dataset included in the feature. ARMAD integrates pavement structure and materials property information for Asphalt Concrete (AC), Portland Cement Concrete (PCC), unbound granular base/subbase, stabilized base/subbase, subgrade, and other layers such as surface treatments and engineering fabrics. The users are also provided with supporting information when downloading ARMAD data, including data statistics, data sources, and a variability indicator.

Once fully implemented, the Analysis-Ready Datasets hub will also include performance, traffic, and climatic datasets.

There are 2581 of 2581 sections currently selected.
