Hot Machined Asphalt for Cold Application
- How Does It Work?

Cold asphalt or hot-machined asphalt for cold application, commonly sold in bags, is a Hot-Machined Bituminous Concrete with the addition of polymers and additives that delay the curing (or hardening) of the asphalt, thus enabling its storage and cold application, mainly in small quantities.

The manufacturing process is similar to conventional asphalt, where stone aggregates and petroleum asphalt cement are hot mixed in an asphalt plant. During this process, polymers and additives are added that allow the prolonged use of asphalt even after it is cold.

When it leaves the plant, the cold asphalt is stored and bagged for sale, but in some cases, it can also be supplied in bulk. These are used in asphalt paving Winnipeg. In addition to being able to be bagged and stored, the cold application also provides several advantages. White Group paving Winnipeg has the expertise and equipment to help you build or maintain a beautiful asphalt surface on your property.

  • Can be applied in the rain or holes with water - Unlike conventional asphalt, cold asphalt can be applied in the rain or holes with water. Conventional asphalt must be applied and compacted hot, and therefore when it comes in contact with rainwater or a puddle, it cools quickly, losing its resistance and adhesion capacity. On the other hand, cold asphalt is designed to be applied and compacted at room temperature. It does not suffer this sudden cooling in contact with water and maintains its grip and support capacity.
  • Alternative Compaction - The traditional compaction used in common paving works is not necessary when using cold asphalt. In general, smooth rollers or tires are used, high productivity equipment that can compact large areas of asphalt quickly. As conventional asphalt needs to be applied and compacted at high temperatures, this service must be performed quickly before the asphalt cools down. With cold asphalt, this equipment, which in most cases is very expensive, does not need to be used. In most applications, a vibrating plate or the car or truck tire itself is enough to carry out compaction; this facility is also provided by the polymers and additives that improve the asphalt mix's workability.
  • Non-emulsified - In addition to facilitating compaction, the polymers and additives added to the asphalt mix do not require priming and bonding paint at the time of machining. These two stages precede the conventional asphalt mix's application stage and allow the perfect adhesion of the asphalt to the base layer. In the case of cold asphalt, these phases are unnecessary because the additives present in the same provide the perfect adhesion of the pavement to the lower layers without sticking to the cars' tires or the soles of the shoes.
  • Storable for up to 12 months - As mentioned before, cold asphalt allows it to be bagged and stored for up to 12 months without prejudice to its application. The additives and polymers added to the mixture create a film around the dough, protecting the asphalt from unwanted compaction and hardening.
  • Easy application - As cold asphalt can be bagged and easily transported, it is easy to apply, and since it is not emulsified, it comes ready for application. Just clean the place, open the bag, spread the dough and compact.
