What Is The Difference Between Asphalt & Bitumen Driveways?

There is a significant distinction between bitumen and asphalt. Bitumen is used to bind the road material together by spraying it and then covering it with aggregate. In contrast, asphalt is a premixed bitumen, aggregate, and sand combination put to the surface using a paving machine to the desired thickness. In a nutshell, bitumen is the binding material for pavement, similar to cement in concrete. In contrast, asphalt is the concrete used to construct roads, and an experienced asphalt driveway contractor does it.

Durability

Asphalt driveways are more durable, with a layer depth of 22 to 40mm and a lifespan of more than 20 years. Bitumen-sealed surfaces or pavements, on the other hand, are thought to be less durable. They have a layer depth of 10 to 20 millimetres and a lifespan of 5 to 10 years. If you are thinking of paving your surfaces, asphalt might be a better option than a bitumen-sealed surface. However, the location of the surface and its intended usage must be considered. Bitumen is a wonderful, low-cost choice for low- and slow-traffic locations. The asphalt investment is more warranted for more hard-wearing surfaces such as roads, motorways, and mining roadways because of its better durability.

More Skid Resistant

Asphalt pavement is smoother and more skid-resistant than concrete. This ensures driver safety and reduces noise, which is why they are utilised on highways and roads. The bitumen driveways surfaces are better suited to slower moving traffic and walking routes because they allow for a noisier driving experience and tend to wear down tyres, contributing to safety hazards.

Level of Friction

Asphalt lowers friction between the vehicle and the tyres, resulting in higher fuel efficiency and lower CO2 emissions. Bitumen, on the other hand, creates greater friction resistance, resulting in lower fuel economy.

Permeability

Asphalt is a substance that is moisture resistant. Because asphalt pavement does not leach, there is less danger of infiltration and polluting of subsurface water. It is possible for bitumen to leach, resulting in soil deterioration and groundwater pollution.

Sensitivity to Temperature

Because asphalt is less sensitive to temperature, it might have detrimental consequences in exceptionally cold or hot temperatures. Because bitumen surfaces are prone to severe temperatures, which can cause them to become soft and slick, weather conditions must be addressed when deciding between asphalt and bitumen.

Cost of Installation

If you are seeking a low-cost option, bitumen should be your first choice. The asphalt driveway costs are more expensive to install, but they do not require routine maintenance, only routine inspections. On the other hand, bitumen is less expensive to install, but it will require regular maintenance, which will raise the long-term cost. The pavements will need to be resurfaced, especially if they receive a lot of traffic. Bitumen is not a long-term answer, but it is a cost-effective one in the near term.

The End Line

The decision between bitumen and asphalt is based on the installation's circumstances, such as budget, location, and usefulness. If you have a limited budget, bitumen is likely the best choice because it costs around half as much as full asphalt, whereas asphalt is more expensive but more resilient and long-lasting. Bitumen is ideal for low- or slow-traffic locations such as car park construction and driveways, whereas asphalt is the preferred material for motorways, roadways, and high-traffic regions.
