The PatchPortal system is intended to meet the needs of Smart Cities and features digital data collection. This allows users to control and evaluate the resources and work of fleets more efficiently than before.

The machines are equipped with GPS and GSM systems and can store located data on repairs carried out by the unit (or fleets of units) on the firm’s web portal. This portal is accessible from any computer or smartphone. All of the necessary data is immediately shown in the table and on a map. This data includes the amount of the aggregate and emulsion built into each single cavity and the air temperature and humidity at the time of the repair. It also includes a quality indicator, showing if all of the steps of Blow Patching technology (cavity cleaning, tack-coat layer, emulsion and aggregate mixture application, aggregate application) have been used in the correct order.

This allows the firm to confirm the quality of each repair, or in case of any deviations in the patching process, it can start taking preventive measures. Any encountered problems are marked red in the system. Additionally, creating a detailed report in excel file is possible.

EasyPatch meanwhile is an electronic system designed to ensure the constant quality of each repair, automatically regulating the amount of emulsion used in Blow Patching process. The operator sets the desired percentage of emulsion in the mixture, and the computer regulates the quantity of sprayed material dependently of the aggregate amount.
