| Material | Specification | Quantity |
|---|---|---|
| Pervious Concrete | * 28 day compressive strength = 5.5 to 20 MPa * Void ratio = 14% - 31% * Permeability = 900 - 21,500 mm/hr |
Thickness will range from 100 mm-150 mm depending on the expected loads |
| Porous Asphalt | * open-graded asphalt mix with a minimum of 16% air voids * Polymer can be added to provide additional strength to heavy loads |
Thickness will range from 50 mm-100 mm depending on the expected loads |
| Permeable Pavers | *ASTM No. 8(5 mm dia) crused aggregate is recommended for fill material in the paver openings. *Pavers shall meet the minimum material and standard specification for Precast Concrete Pavers. *Pigment in concrete pavers shall conform to ASTM C 979 ACI Report No. 212.3R provides guidance on the use of pigments. *Maximum allowable breakage of product is 5% |
*For vehicle applications the minimum paver thickness is 80 mm *For pedestrian applications is 60 mm and Joint widths should be no greater than 15 mm. |
