Under the contract to carry out the Multiannual Investment Plan for the provinces of Tucumán, Santiago del Estero, Salta and Jujuy financed by the World Bank, the AC&A road survey division is currently carrying out the analysis of more than 5,000 kilometers of paved network through the Falling Weight Deflectometer (FWD) type tests.

These non-destructive tests are being performed to calculate the structural capacity of the routes, which will then be modeled in the HDM-IV software.
