Asphalt Designed for You
As the area's top asphalt provider, we have our own state-of-the-art laboratory and state-certified technicians to create unique mix designs for each asphalt project. We have a wide array of resources available below to help you design your asphalt pavement and learn more about the construction process.
Perpetual Asphalt
We recommend a perpetual asphalt pavement, an engineered pavement designed to last forever. It is durable and efficient to maintain throughout its lifetime. When you construct with perpetual asphalt today, you are making an environmentally conscious and financially responsible investment for the future.
Benefits of perpetual aspahlt pavements
They've proven to withstand traffic growth successfully
They have a small carbon footprint
They create less hassle for the driving public
They're easier on the environment than other pavements
They last a long time
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
