CMAA’s DesignPave program can be used to design and analyse concrete segmental pavements (CBP). It employs the Method of Equivalent Thickness to compute the most appropriate design for the identified pavement loading and soil conditions.
The latest update to DesignPave includes a new hydrological methodology to design permeable pavements, which allow rainwater to infiltrate the ground below. The software incorporates new knowledge and technology developed by the industry and research sectors.
DesignPave can be used for both residential and industrial pavement applications.

DesignPave has been developed in collaboration with the University of South Australia as a successor to LockPave, which was based on the works of Dr. Brian Shackel, a world-leading authority on pavement technologies. The old LockPave software key has been discontinued, however many of LockPave’s principles and methods can still be found within DesignPave, updated for modern pavement applications.
Where PermPave was a separate software from LockPave, it is now an integrated feature within DesignPave, also updated for modern water storage and harvesting applications. The DesignPave package comes complete with the DesignPave software for mechanistic design, as well as the PermPave software for runoff control and together they form a comprehensive design package for any concrete block pavement applications.
A description of how to do this is given in Austroads’ Guide to Pavement Technology, Part 2.
In the method of equivalent thickness, converting the layers to one layer with a constant modulus has a factor of safety of 1.25 built in.
The default is a dentated block, corresponding to a recommended modulus of 3200 MPa and Poisson’s ratio of 0.30. These values can be manually adjusted according to the block type – block size does not have an impact in terms of design but will have an impact on the block properties (breaking load). In the help files in the design screen, there are recommendations for different moduli and Poisson’s ratios.
DesignPave offers simplistic cost analysis capabilities. The total cost of pavers ($/square metre), and ($/cubic metre), base course ($/cubic metre) and other items can be edited to suit the needs of the project. Guidance on what might be considered in ‘other costs’ can be found in the help file. The software will calculate the cost per square metre of the designed pavement.
