It's look like concrete
It's the colour of conctete

But in fact it's colored asphalt.
I passed last week and i notice a strange "granulat" in the junction with the paving stones near the street. So yesterday, i saw the new part in construction (black aphalt in same level of the street) and i ask a contractor worker and they will just add a spayed paint to it (grey)
