Using HMA which stands for Hot-Mix Asphalt offers an economical and efficient construction process which is backed by unsurpassed versatility. When repairs or rehabilitation becomes a requirement, it can be achieved quickly without much user delay. Asphalt pavements provide a significant advantage for all types of projects. Here are a few of the top benefits associated with investing in an asphalt mixer for sale:
1. Economical
Asphalt is recognized as one of the most cost-effective choices as it can be constructed as a “perpetual pavement” which leads to much lower costs for users.
2. Recyclable
Among the important advantages linked with HMA (Hot-Mix Asphalt), is that these materials are completely recyclable. These aggregates are used again while the binders in the asphalt also manage to maintain adhesive properties, which is often used again in the next HMA mix. Pavements that are recycled in conventional HMA mixing plants for sale, require very little modifications. At the same time, these materials are able to perform in the same way as the virgin-aggregate mixes.
These asphalt mixers are also able to handle RAP (reclaimed asphalt pavement). HMA pavements are usually 100% recyclable and are a service or product that is recycled the most in countries like the China.
3. Ease Of Construction
As soon as the drum-mix alat berat amp is placed, time-consuming tasks such as steel-reinforcement and formwork are eliminated already. Once placed, cars and pedestrians can use these pavements almost immediately as there are no delays required. In addition, when repairing a road, asphalt surfaces are faster and easier to perform, due to basically no downtime needed.
Continuous mixing plants happen to be the ideal choice for plants that work on specific projects that do not require regular alterations or changes to the mixture. The batch plants, on the other hand, are better suited to users that need to change the mixes frequently. Continuous mixing plants use a method that if one part had to stop working so will everything else.
When using a continuous plant, virgin aggregates that come from the cold-feed bins are typically fed by a conveyor belt according to the weight or volume, that matches up to the gradation associated with the mix design. These aggregate mixtures then flows up the cold feed elevator or conveyor where it enters what is known as the “counter-flow” asphalt drum mixer.
As the virgin aggregates move from one side of a drum to the other, the mixture slowly starts to warm up. The air that flows through these drums picks up the fine dust in the aggregates. This dust is then collected and stored in a baghouse. From the other side of these drums, the RAP enters and is then heated by the super-hot, virgin aggregates. The RAP and virgin aggregates combine where they are then stored inside an HMA silo or storage. From here the mixture is distributed into trucks that transport these mixtures to a construction or job site.
