The Pavement Preservation & Recycling Alliance (PPRA) has a great Treatment Toolbox that is available for free as an online resource for your pavement preservation planning.
One of the available tools allows you to select appropriate treatment candidates based on the pavement condition index (PCI), primary distress, road type, and the surface type. In the example to the right, an urban local asphalt road in good condition, with some longitudinal and transverse cracks is a candidate for fog seal, slurry seal, microsurfacing, ultra-thin lift, chip seal, and others. Take a moment to experiment with the tool and you will see that it is an easy way to narrow down your options for a given pavement condition.

An alternative approach is to explore methods based on photos. With this tool, you can browse their photo library to spot roadway conditions similar to yours and receive more information about the distress type, as well as possible preservation techniques.
From either of these tools, you can link to more information for candidate preservation technologies, but you can also learn more about them directly by visiting the Treatment Resource Center.
Yet another tool on PPRA’s site is the Cost Calculator. Here, conventional approaches can be compared to appropriate pavement preservation tools, using generalized unit costs or by substituting your own.
Yet other tools on the site are the structural comparison calculator and the life cycle cost calculator, among others.

Take a few minutes and explore the PPRA tools to see how you can use them in planning your pavement management going forward.
