Bitume Stradale 170/210
Soft paving grade bitumen, also the base for SBS waterproofing membranes
Bitume Stradale 20/30 is a paving grade bitumen produced by Eni. Its very high resistance to ageing and its plasticity make it a hard binder for the asphalt mixtures used on roadways, runways, pavements, race tracks and landing platforms, and it is chosen in particular where the mix has to resist deformation. 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.
