Asphalt is considered one of the best materials for paving driveways, roads, parking lots, and other surfaces. It is durable, cost-effective, and long-lasting. Asphalt is a combination of sand, gravel, and bitumen. The bitumen acts as a binder that holds all the components together to create a smooth surface that can withstand heavy traffic and harsh weather conditions. There are different types of asphalt paving techniques that contractors use to create these surfaces. In this article, we will explore some of the most common techniques.
Standard Paving
Standard paving technique, also known as “hot mix asphalt,” is the most commonly used technique in the industry. It involves heating up the asphalt mixture to a temperature of around 300F and then spreading it on the prepared surface, usually with a machine called a paver. The asphalt is then compacted with a roller to create a smooth surface. Standard paving technique is best for large projects that require a lot of asphalt, as it is the most cost-effective and efficient technique.

Mill and Fill
Mill and fill is a technique that is used when the surface is severely damaged and needs to be repaired. In this technique, the existing pavement is removed, and a new layer of asphalt is added to the surface. The milling machine grinds off the top layer of the damaged pavement, and then a paver lays a new layer of asphalt on top. This technique is best for surfaces that have potholes, cracks, and other surface damage. Mill and fill can also be used to improve drainage on the surface, making it more resistant to standing water.
Cold Mix Asphalt
Cold mix asphalt is used when the temperature is too cold for hot mix asphalt. It is created at a lower temperature and can be stored for months without losing its quality. Cold mix asphalt is not as strong as hot mix asphalt, but it is still a good option for small repairs or areas with low traffic. It is also ideal for patching potholes during the winter months when hot mix asphalt cannot be used.
Perpetual Pavement
Perpetual pavement is a technique that is becoming more common in the industry. The technique uses multiple layers of high-quality asphalt and aggregates to create a surface that can last for decades without needing major repairs or replacement. The top layer of the pavement is usually high-quality hot mix asphalt, and the layer beneath it is a stronger and thicker layer of asphalt binder. The bottom layer is comprised of coarser materials that provide a strong foundation for the surface. Perpetual pavement is a more expensive option, but it is worth the investment as it will save you money in the long run by reducing maintenance and repair costs.
Conclusion
Choosing the right asphalt paving technique depends on the specific needs and requirements of your project. Each technique has its own advantages and disadvantages, and it’s important to consult with a reputable contractor to determine which technique is best for your surface.
