Hot Asphalt vs Cold Asphalt

Since time immemorial, the age-old questions has been: What material can we all use to prevent cracks on our Lakeland parking lot paving? Again and again, people and governments are wondering what efficient and indestructible material can be used to patch potholes and build roads.

The answers is: there is none. All materials–whether asphalt or concrete–used on roads and parking lots are susceptible to breakage and cracks, no thanks to extreme weather conditions and the weight of vehicles passing on it.

Throughout the history of American roads, the one thing that irritates people the most are unpatched potholes on the road. Road construction is almost always forgiven because these are scheduled and there are alternative routes provided when a construction is underway. It’s a different matter altogether when potholes remain unrepaired because it can cause accidents and can disturb the flow of traffic.

When patching potholes, there are basically two kinds of asphalt mixtures you can choose from–the hot mixture and the cold mixture. What’s the difference?

Hot asphalt is mixed at around 300 degrees Fahrenheit, and the paving, patching and compaction must be done while the asphalt mixture is still sufficiently hot. With the hot mixture, construction and repair of roads and parking lots can only be done during the warmer months. Winter will cool the asphalt as soon as it hits the ground, and it will permanently disable the binder in the hot mixture.

Cold asphalt, on the other hand, is mixed and use at lower temperature states. Cold mixture asphalt is easier to use, manage and work with in colder temperatures as opposed to hot mixture asphalt. In fact, if a cold asphalt is well designed, it can very well take on the features of hot asphalt. It has the capacity to be as strong and durable as hot asphalt. The only problem with cold mixture is that some contractors see it as a temporary solution; kind of like a bandaid on a scratched knee. It seals the cracks, but only for a short while.

The other thing that separates these two types of asphalt mixtures is the magnitude of the construction or repair job. Larger jobs tend to use the hot asphalt because there is no need for a propane or diesel heating systems. Since businesses often schedule the construction of Lakeland parking lot paving during the summer or drier months, it makes more sense for them to use hot mixture.
