Bitumen MC70 in sealed steel drums, supplied by Basekim for prime coating and surface treatment in road construction projects.

Bitumen MC70 is a medium-curing cutback bitumen made by blending penetration-grade bitumen with kerosene. Road construction teams use it to prime and seal unbound base layers before applying hot mix asphalt. Its perfect flow and balanced curing speed make it ideal for both urban and remote infrastructure projects.

At Basekim, we produce and supply high-quality bitumen MC70 for road contractors, infrastructure firms, and public projects worldwide. Because we control production, testing, and delivery, we ensure top performance and on-time shipping for every order.

How Bitumen MC70 Works in Road Construction

Construction crews apply bitumen MC70 as a prime coat to unbound or stabilized road bases. After spraying the material on the surface, it quickly penetrates the granular layer. As the solvent slowly evaporates, the remaining bitumen forms a strong, adhesive film. That film bonds the base and the asphalt layer placed above it.

In moderate to warm climates, MC70 offers excellent performance. It cures at just the right speed—faster than heavier grades but slower than rapid-curing options. Because you don’t need to heat it, you can apply it with simple spraying equipment, which reduces energy costs and safety risks.

Why You Should Use Bitumen MC70

When you choose MC70, you gain several key benefits. First, it gives you flexibility. You can apply it without heating equipment, which makes it ideal for remote areas or quick projects. Second, it allows enough curing time to create a solid bond with the base.

By using MC70, you extend the life of your asphalt pavement. The strong bond it creates improves resistance to moisture and heavy traffic. As a result, your roads perform better and last longer.

Many engineers also choose MC70 for dust control or light surface treatments. Because of its medium-curing properties, it adapts well to different weather and soil conditions.
