Steps for Designing an Asphalt Pavement

Step 1: Determine the type of loads the finished system will be required to support

Step 2: Evaluate the load baring capacity of the subgrade

Step 3: Identify the soil type (sandy, clay, stone and silty clays) to predict subgrade performance

Step 4: (optional): For weak subgrades remove and replace with higher quality fill

Step 5: Consider surface and subsurface drainage (Where is water coming from and where do we need it to go?)

Step 6: Determine your reliability factor

Step 7: Plug in your data with an easy-to-use pavement design tool know as I-Pave™

Step 8: Review the Iowa Department of Transportation Standard Specifications for the class and mixture size required
