Temperature plays a critical role when it comes to determining the results that one gets when paving with hot mix asphalt. This is because how hot the asphalt is usually determines whether or not proper compaction takes place and hence the durability of the asphalt pavement.
However, that is not all there is to the asphalt-temperature relationship. It turns out that in addition to determining whether or not compaction takes place, the temperature of the mix also determines the rate at which the compaction takes place. This is important to you as a homeowner mainly because it is something that affects your construction costs.
Generally, the colder the hot mix asphalt is, the longer it will take for the rollers to effectively compact it. This means increased labor, fuel and equipment costs. In essence, keeping track of the temperature of your asphalt is important because it is a risk to both the durability of your pavement and the health of your wallet. Here are some of the things that you should keep in mind when laying your asphalt pavement.
The distance matters
When weighing the decision on where to get their hot mix asphalt, most homeowners usually consider the costs of transporting the asphalt. The only problem is that they usually forget to factor in the effect that the decision has on not only the durability of the pavement but also the costs of construction.
Distance matters mainly because the hot mix asphalt usually loses heat when in transit. And the farther the source of the asphalt, the more the temperature drop. What this means is that even if the far-off place is cheaper in terms of the cost of the asphalt, it might not be a good idea to choose it over one that is next to your the construction site simply because of the effect that the distance difference can have on both the quality and costs of your project.
The weather matters
In cold weather, the Hot Asphalt Mix will lose temperature at a faster rate when in transit. How cold it is will also affect the temperature of the base on which the asphalt has to be laid. This will affect the rate of compaction since the hot mix asphalt will essentially have to warm the base first, before proper bonding can start to take place. And things only get worse when rain is added to the equation not only because the rain water will reduce the temperature of the asphalt mix, but also because it introduces moisture into the mix – something that makes bonding harder.
