Curing procedures shall begin immediately following placement operations. The pavement surface shall be covered with a minimum six (6) mil thick polyethylene sheet or other approved non absorptive, water impermeable covering material within 30 minutes of concrete discharge from the truck. Prior to covering, a fog or light mist shall be sprayed above the surface when required to replace water which evaporated due to ambient conditions (temperature, wind, and low humidity). The cover shall overlap all exposed edges and shall be thoroughly secured (without using soil or other fine material which is subject to be displaced by wind or water) to completely encapsulate the pervious concrete and to prevent dislocation due to winds or adjacent traffic conditions
