GOMACO Smoothness Indicator (GSI) checks concrete pavement rideability as the paver lays concrete. Readings are displayed on a 7-inch diagonal touch-screen monitor, and an adjustable mount allows for setting the optimum viewing angle. The GSI traces the slab and takes smoothness readings simultaneously from three different sensors in each trace, and it can trace up to eight wheel tracks for a total of four lanes in a single pass. It will provide smoothness readings in multiple indexes, including the GSI number, IRI, PI (profile index based on the California profilograph), or it can be exported as an .erd file to create several other indexes.
