Pavement Thickness Design Evolves With Latest Software How thick should I specify the asphalt on my project, considering the number and types of traffic loads I expect, and the support I think the subgrade will provide?” That is the basic question posed by engineers who want their pavement to last a long time, and in good condition. Pavement thickness designs are too often based on economics — how thick can the pavement be built with the dollars available for the project, regardless of the engineering realities. Or they are simply empirically-based — what has been observed to perform under similar conditions before.

In the late 1950s and early 1960s, a large-scale experiment was performed by the American Association of Highway Officials (AASHO). Six pavement loops, consisting of several different pavement cross sections, were continuously loaded to try to simulate a lifetime of fatigue in just a couple of years. The same level of traffic caused differing amounts of distress to the different sections. The analysis of the work resulted in a guide that has been used ever since, the AASHTO Guide for Design of Pavement Structures (the “T” for “Transportation” was added in 1973). One of the strengths of the design process outlined in the guide lies in the fact that even though it is empirically based, decades of experience have demonstrated that the method is fairly rigorous and typically provides reasonable thicknesses as long as the data used to design the pavement is reliable. However, one of its weaknesses is that the equations used for pavement analysis are very complicated. It took a certain level of training to properly use the nomographs and other tools necessary to make the calculations. Mechanistically-based pavement thickness design methods are even more complicated to use and have, to date, required sophisticated computer software and more specialized training. Pavement design engineers in state and federal agencies have the necessary training and resources, but often city, county and private consulting engineers and managers do not. But what if there was a way to design and document asphalt pavement thickness easily, that anyone could use? A way that used the accepted methodology of the AASHTO pavement design guide, a way that was user-friendly? Software as a solution Pavia Systems, with sponsorship from the Asphalt Pavement Alliance (APA) and its constituent members, has developed free online pavement thickness design software called Pave press. The software simplifies the process of using both the 1993 AASHTO design guide for asphalt pavements and 1998 AASHTO supplement for concrete pavements. The software is brimming with quick help buttons to assist the designer with obtaining and properly inputting the necessary information.
