The American Association of State Highway and Transportation Officials (AASHTO) flexible pavement design method is a widely used approach for designing flexible pavements in the United States. This method provides a framework for evaluating the structural integrity of flexible pavements and predicting their performance over time. One of the most popular tools for implementing the AASHTO design method is an Excel spreadsheet, which simplifies the calculations and allows engineers to quickly evaluate different design scenarios. In this article, we will provide an in-depth look at the AASHTO flexible pavement design method and explore how to use an Excel spreadsheet to streamline the design process. This method provides a framework for evaluating the

You can quickly adjust layer thicknesses (e.g., swapping a thicker base for a thinner subbase) to find the most cost-effective design .
