Properly installed permeable pavement requires trained and experienced construction contractors. The following general recommendations apply:
Properly installed permeable pavement requires trained and experienced construction contractors. The following general recommendations apply:
*'''Sediment Control''': The treatment area should be fully protected during construction so that no sediment reaches the permeable pavement system. Construction vehicle traffic should not be permitted on the permeable pavement and its drainage areas once the pavement has been installed.

*'''Base Construction''': Aggregate should be placed in 100 mm to 150 mm lifts and compacted with a minimum 9 ton steel drum vibratory roller. A light weight deflectometer may be used to test compaction level of open graded stone and compare to specifications.
