Permeable Design Pro Upgrade
Permeable Design Pro, a software application for hydrologic and structural design of permeable interlocking concrete pavement, now features CAD drawing output (see example drawing). Drawings are generated by the program after calculating the subbase thickness for water storage and subgrade infiltration, as well as the required subbase thickness to support anticipated traffic. The program automatically selects the thicker of the two subbase solutions and presents the CAD drawing from a menu selection. The drawing can include an underdrain, geotextile, and an impermeable liner if no infiltration into the soil subgrade is desired. The CAD drawing also specifies the height of the underdrain outlet, if the designer indicates this in the program, as a means to detain some water for infiltration.
Also, the user can modify the CAD drawing by changing the subbase thickness and the underdrain pipe diameter, as well as the presence or absence of geotextile or an impermeable liner. The CAD drawing can be saved as a .dwg file for use in project drawings or submittals.
Permeable Design Pro can be downloaded from www.permeabledesignpro.com for a 30-day free trial. The purchase price is $190 per license with a discounted price of $95 for design professionals and ICPI members.
