FlexPave

Planning a new road or highway can go beyond the obvious, 2D route setting as there is a myriad of subsequent factors and characteristics that need to be accounted for. When looking at the substrate structure for any given road or highway, things can get complicated really quickly. FlexPave was designed specifically for dealing with the methods and procedures presented in the AASHTO Pavement Design reference manual and it will provide users with the means of creating and editing a pavement structure plan, with customizable graphical and numerical parameters.

The main working principle behind the app’s functionality relies on the use of graphics for depicting the actual pavement structure. This is done in accordance with the principles and parameters presented in the AASHTO documentation.

Indices such as sub-grade CBR, growth rate, design life or AADT are just some which can be defined right when initiating a new project. Further, more advanced parameters can also be tweaked.

Using three depths as the main areas for parameter customization, the app allows users to define a specific set of characteristics for the surface layer, base course and sub base.

A nifty graphical representation is met with a slider that controls the scale, which can be useful when trying to change perspective.

Regardless if you’re an engineer trying to develop the plan for a new highway or you’re just learning about the particulars of pavement structure design, this app can help you perform an advanced pavement planning process.
