Properties and applicability of pervious concrete for paving flags

Pervious concrete is a type of a concrete designed and installed to have high porosity which reduces its me-chanical properties. But this feature is also resulting in its most favorable property, remarkable drainage properties making it a desirable green pavement solution for specific areas. Properly designed and installed pervious concrete pavement presents an optimal solution for low volume areas and particularly, bicycle and pedestrian infrastructure. Pervious concrete has been studied extensively over the past 40 years, but still there are no European standards for its testing and installation. Mainly, international researchers are dealing with pervious concrete composition and mechanical properties improvements for its usage as concrete slabs or monolithically constructed concrete pavement surfaces. Within this paper, experimental research will be presented on pervious concrete properties for the production and installation of pervious concrete paving flags. On laboratory produced pervious concrete paving flags, weathering resistance by water absorption measurement, bending strength, abrasion resistance and drainage by ASTM C1701 were conducted varying pervious concrete mix composition.
