Originally released in 2008 by the Interlocking Concrete Pavement Institute (ICPI), Permeable Design Pro Software v2.0 for permeable interlocking concrete pavement (PICP) now features CAD output of design solutions. The program generates time-saving PICP cross section drawings with base and subbase thicknesses for use in project drawings. The CAD drawings illustrate calculated hydrologic and structural requirements from user-designated rainfall events, runoff flows from contiguous surfaces, traffic loads, underdrains and soil subgrade characterizations. Permeable Design Pro v2.0 enables users to quickly evaluate PICP solutions for stormwater management for pedestrian areas, parking lots, alleys and streets.

Upon calculating the subbase thickness for water storage and anticipated traffic loads, the program automatically selects the thicker of the two subbase thickness solutions and presents the PICP cross section as a CAD drawing. Based on user inputs, drawing outputs can include an underdrain, geotextile, and an impermeable liner if no infiltration into the soil subgrade is desired. The cross section drawing also specifies the height of the underdrain outlet as determined by the user to detain water for infiltration. The user can also directly modify the drawing cross section output from within the program. Items that can be changed include the subbase thickness, underdrain pipe diameter, the presence or absence of geotextile, and an impermeable liner. The CAD drawing can be saved as a DWG file.

Other program modifications include the minimum surface infiltration required for designs now set at 100 inches/hour. PICP has substantially higher initial surface infiltration rates, but this value is used as a starting point to facilitate intake of all rainfall and runoff from adjacent surfaces into low or no slope PICP. The user can increase this infiltration value in the program based on manufacturer-supplied surface infiltration data.    

The new software version can now be instantly downloaded from http://www.permeabledesignpro.com for a 30-day free trial period. After the 30-day trial period has expired, users can purchase a license key to register and activate the software to continue using it.

Complimentary ICPI Webinar:

PICP Design Using Permeable Design Pro
February 25, 2015 at 1 PM EST

Presented by:
David Hein, P. Eng., Principal Engineer and Vice-President of Transportation, Applied Research Associates, Inc. and Rob Bowers, P. Eng., Director of Engineering, ICPI

This webinar demonstrates Permeable Design Pro software which calculates the structural and hydrological requirements for open-graded aggregates in permeable interlocking concrete pavement (PICP). The presenter explains many of the key input variables such as rainfall events, run-on, soils, traffic loads, pavement materials, etc., and demonstrates their impact on outputs including infiltration, outflow rates/volumes hydrographs, subbase thickness, etc. A few design examples are demonstrated that illustrate relationships among these inputs, outputs and the selected design. The presentation also illustrates the pavement section options illustrated as CAD drawings generated once design outputs are calculated and selected.
