Patching is a common method of treating any damaged area on asphalt surfaces. These damages can either be full depth where they extend from the pavement surface to the subgrade or they can be partial.
The big deal is the patching material. Patching material can be any hot mix asphalt or cold asphalt as well as some form of slurries. If you have an asphalt paving project coming up you want to know the difference between the two and how they can be used.
What is hot mix asphalt?
As the name suggests, it is a mixture of aggregates like gravel and sand, and asphalt cement that requires heating before installation. It is mostly useful for large-scale paving applications like roads, parking lots, and driveways.
Patching with hot mix asphalt is the best way when it comes to repairs because it is more permanent.
On the other hand, cold mix asphalt is most useful for repairs of small cracks and potholes or patches when the outside temperature is too cold for hot mix asphalt.
Asphalt patching techniques
There are several different methods involved when patching with hot mix asphalt. They include;
- Saw cut and patch: this method involves the removal of deteriorated sections of pavement and filling the sections with hot mix asphalt.
- Milling and patching: this involves grinding a pavement surface to the desired depth so that a new layer of hot asphalt can be put on top.
- Infra-red patching: it involves an asphalt surface, heated by innovative machinery allowing it to be workable in any weather above 0 degrees.
