The Complete Guide to Permeable Paving Systems

Permeable paver parking lot at UC Santa Cruz in California Permeable paving systems are porous, so they allow water to infiltrate the pavement and drain into the ground or sub-base rock underneath These paving systems are just as strong and durable as traditional paving materials such as concrete, asphalt, or compacted gravel.

Porous Asphalt

Porous asphalt pavements offer developers and planners a new tool in their toolbox for managing storm water These pavements, used mostly for parking lots, allow water to drain through the pavement surface into a stone recharge bed and infiltrate into the soils below the pavement Such pavements have been proving their worth since the mid-1970s.

Early Permeability Test for Asphalt Acceptance

16 Abstract: One of the primary assumptions in structural pavement design for conventional pavements is that a flexible (hot mix asphalt) pavement be impermeable The basis for this design approach is to minimize moisture infiltration and thus maintain adequate support from the underlying unbound materials.

Correcting permeability in dense-graded HMA mixes

Asphalt mixes can be designed to greatly reduce permeability A lab permeability test can provide valuable information regarding the potential porosity of the pavement Finally, proper in-place density is critical to produce a watertight pavement The roadway life can be extended for years by keeping moisture out of the pavement structure.
