Pittini Group, key player in a highway maintenance program

Pittini Group, key player in a highway maintenance program

Pittini Group has recently taken part in an important highway maintenance program.

The intense circulation of heavy vehicles on important arteries calls for precise surface maintenance interventions to minimize inconveniences. Against the backdrop of a scheduled high-traffic road surface reconstruction in Northern Italy, the works supervisor has chosen Granella® by Pittini Group - a special solution that combines durability, load resistance, and environmental sustainability. This absolutely innovative material comes from industrial waste and is transformed - through dedicated production processes - into a product with peculiar physical-mechanical characteristics. Granella ® is ideal to manufacture bituminous coverings, cementitious coverings, and concrete mixes, as it can increase the durability of the road surface by enhancing its micro-roughness. As a derivative of steel mill slag, Granella® also allows to considerably reduce the use of exhaustible raw materials, thus being an eco-sustainable and environmentally friendly solution.

First, the road surface has been milled. Then, after the application of a bituminous emulsion, it has been covered with a single layer of high viscosity bitumen and aggregates - Granella®. In 2022, when the maintenance program will be completed, 430,000 square meters of road surface will have been asphalted with over 15,000 cubic meters of Granella® in two grain sizes (4-8 mm and 8-14 mm).
