I just found out that the Portland Cement Association is offering the Hydrologic Design of Pervious Concrete manual for free as a pdf download off their Web site for the next month only. The manual is a 72-page publication for engineers, landscape architects, developers, and other design professionals who are interested in designing or reviewing designs of pervious concrete pavement.
Pervious pavement is a newer type design that creates a pavement with voids. This design allows storm water to drain or percolate through the pavement material into an underlying collection layer or into the native soil.
The URL for downloading this manual is: http://www.cement.org/bookstore/profile.asp?itemid=EB303
But hurry because it is only being offered until 3/31/2008 according to their site.
