The American Concrete Pavement Association (ACPA) has a free, online version of its popular StreetPave design software, which can be used for both roadway and highway pavement design.  This easy-to-use online version allows a designer to use the software by following five quick steps:

    1)  Choose design/analysis type.

    2)  Enter project level design constraints/requirements.

    3)  Input traffic characteristics.

    4)  Input pavement properties.

    5)  Run analysis and view results.

If you have the original version of StreetPave, ACPA has a free patch to upgrade it to Version 1.2.  The upgrade includes enhancements to the dowel bar recommendation feature, additions to the life cycle cost module (inputs and reports), and a new interface for inputting and determining pavement characteristics.
