DENSIPHALT®- a semi-flexible topping
Densiphalt® system – mortar and asphalt
Densiphalt® – mortar1) Standard and shot-blasted surfaces respectively. 2) Resistance through layer 3) Surface resistance.
Densiphalt® consists of an open-graded asphalt, with the voidsfilled with a high-strength cement-based mortar. Densiphalt® isapplied as a 30-100 mm layer, andis laid on an adequate base coursesuch as asphalt, lean-mix concreteor standard concrete. Densiphalt®
can be coloured in a variety ofshades.
