Bitume Stradale 170/210
Soft paving grade bitumen, also the base for SBS waterproofing membranes
Bitume Stradale 50/70 is a paving grade bitumen produced by Eni. Its high resistance to ageing, its plasticity and its behaviour at low temperatures make it a binder for the bituminous mixes that form the flexible structure of roadways, runways, pavements, race tracks and landing platforms. Approximate working temperatures: storage 160-170 °C, mixing 160-180 °C, compaction 150-170 °C. The maximum recommended handling and storage temperature is 200 °C.
