As a paving contractor, your services are only as good as the materials you’re putting down. Low-quality hot mix could compromise the integrity of the entire project, leading to dissatisfied customers. Additionally, there’s no one-size-fits-all mix for asphalt — a parking lot needs a different mix than a driveway or a road. The guide below explains the importance of asphalt quality design in paving.

Why Does Asphalt Quality Matter?

Asphalt is composed of two key components — aggregate and binder. Aggregate makes up most of the hot mix, often up to 95%. This can include finely crushed rock, gravel, and sand. To hold these materials together, a binder is required. This binder is almost always bitumen, a petroleum derivative. This substance gives asphalt its distinct black color.

The ratio of aggregate to binder and the materials used for aggregate can impact the durability of a project. For example, driveways are often created with a hot mix that uses more binder and a finer aggregate for a smooth surface. A mix of fine aggregate also makes the surface better at shedding water. However, for surfaces with high-traffic and heavier loads, a coarser aggregate may be needed for durability.

How Can You Find the Right Mix?

The easiest way to get the mix ratio right every time is to find a professional asphalt quality design company. Once you’ve described the project that you need asphalt for, they will formulate a mix to provide maximum durability and strength. This reduces the risk of premature cracking, and it ensures you meet state regulations.
