Permeable Paver Construction Inspection Checklist
Regular inspection of your asphalt will ensure that your equipment performs at its best for a long period of time. This will also help in avoiding costly repairs which will eventually make you save lots of money for unncessary repairs.

Pre-Excavation
Roped off area to divert construction vehicles
Runoff diverted: no runoff enters pavement from disturbed area
No runoff enters pavement until soils stabilized in area draining to permeable pavement
Utilities located and marked (USA Underground)
Mark area to be excavated
Walk through with builder/contractor/subcontractor to review Erosion and Sediment control plan
Excavation
Size and location conforms to plan
At least 10ft. from foundation walls
At least 100ft. from water supply wells
Soil permeability: no sealed surfaces, rocks and roots removed, voids refilled with permeable soil
Soil compacted to specifications and field tested with density measurements
Groundwater/bedrock: no groundwater seepage, standing water, or presence of bedrock
Geotextile
Meets specifications
Placement and downslope overlap (typically 2ft.) conform to specifications and drawings
Sides of excavation covered with geotextile
No tears or holes
Minimal wrinkles, pulled taught and staked
Drain pipes/observation wells
Size, perforations, locations, slope, and outfalls meet specifications and drawings
Elevation of overflow pipes correct
Aggregate base course
Sieve analysis conforms to specifications
Laid or spread (not dumped) with a front –loader to avoid aggregate separation
Thickness, placement, and compaction meet specifications and drawings
Aggregate choke course
Sieve analysis conforms to specifications
Laid or spread (not dumped) with a front-loader to avoid aggregate separation
Thickness, placement, and compaction meet specifications and drawings
Edge Restraints
Curb elevation, placement, and materials meet specifications and drawings
Permeable interlocking concrete pavers
Meets ASTM standards as applicable
Elevations, slope, laying pattern, joint spacers (if applicable) placement/compaction meet spec.
Joint materials conform to specifications (aggregate)
Drainage swales for emergency overflow
Pre-treatment drainage area for filtering runoff
Final Inspection
Elevation and slope conform to drawings
Transitions to impervious paved areas separated with edge restraints (curbs)
Stabilization of soil in area draining into permeable pavement (min. 20f.t.vegative strip)
