1. A method of installing and finishing Portland Cement Pervious Pavement with a very efficient, time-saving procedure, comprising the steps of(1). constructing, at desired locations, two parallel forms, spaced apart and sufficient in stability and strength to support the mechanical equipment, and being the length and depth of the finished compacted pavement,(2). constructing a transversal form, positioned to connect the two parallel forms and equal in their strength and height and located at the beginning point of the pavement area,(3). positioning a hot-mix motorized paver between the parallel forms and positioning its screed against the transversal form,(4). installing on each end of the hot-mix paver'"'"'s screed, adjustable ski-type support runners, positioned for each support runner to rest on and move along the top of its respective form, for supporting the screed'"'"'s height and level, as the paver moves between the parallel forms and performs its paving functions,(5). installing behind the hot-mix paver, a compacting roller, positioned parallel to the paver'"'"'s width and having each of its ends connected, by connectors, to the paver'"'"'s rear side respectively, for power movement, and being sufficient in length to span the area between the parallel forms and rest and roll along the top of each form,(6). delivering fresh Pervious Pavement mix into the hot-mix paver'"'"'s hopper,(7). delivering the fresh Pervious Pavement mix through the paver and under its leveled screed at a selected level across the area between the parallel forms and at the selected height above the parallel forms that allows the compacting roller'"'"'s function to compact the fresh Pervious Pavement down to the top of the parallel forms,(8). cutting indentations across the fresh compacted pavement by rolling the hand powered roller, containing a pointed hoop, across the fresh pavement at selected locations, for expansion joints,(9). covering the fresh Pervious Pavement, within 20 minutes after completion of placement and finishing, with polyethylene sheeting, to allow for the proper curing time of approximately seven days,(10). removing the polyethylene sheeting, the parallel forms and the transversal form from the lane of Pervious Pavement, after proper curing time of approximately seven days,(11). removing, from the end of the paved area, any excess Pervious Pavement that extends beyond the desired paved area by the use of a concrete saw, thus completing the paving of a lane of Pervious Pavement.
