Ready mixed asphalt (RMA) plants are the new hot commodity in the paving industry. The reason for this is simple – they’re much easier and faster to set up and operate than traditional batch plants. This makes them ideal for projects where quick turnaround is key, such as schools and sports venues. In this article, we’ll take a look at what comprises a RMA plant, how it works, and some of the benefits that you can expect.
What is ready mixed asphalt?
Ready mixed asphalt is a mixture of asphalt and aggregates, which is typically stored in drums or trucks. The asphalt and aggregates are combined and then delivered to the construction site where it is used as a paving material. Ready mixed asphalt is a cheaper option than traditional asphalt, and it can be used on both residential and commercial properties.
How ready mixed asphalt is made
You may have seen a ready mix truck parked next to a construction site. Ready mix is made up of small batches of asphalt that are mixed together and then put into trucks and hauled to the construction site. The process of making ready mix is called asphalt mixing.
The first step in making ready mix is hauling the raw materials to the mixing plant. Raw materials include sand, gravel, and oil shale. These ingredients are combined together to create a slurry. The asphalt mixture will be made up of about 60% sand, 30% gravel, and 10% oil shale. The mixture is then heated until it becomes a liquid. When the mixture is hot, the oil shale begins to break down and produce tar. Tar makes up the sticky part of asphalt, which gives it its characteristic black color.
Once the tar has been added, the mixture is poured into molds called hoppers. The molds help control the amount of asphalt that gets mixed together during production. The tar-coated slurry is then pumped into large drums or vats where it is stirred with a rotating shaft. This process helps ensure that all of the ingredients are mixed together evenly.

Advantages of using ready mixed asphalt
Ready mixed asphalt is gaining in popularity as a paving solution because of its many advantages. Ready mixed asphalt offers quick and easy installation, reduced labor costs, and fewer environmental concerns. Here are five major benefits of using ready mixed asphalt:
1. Quick and Easy Installation: Ready mixed asphalt can be easily installed using a portable mixer and shovel. This makes it a popular choice for roads and parking lots that need to be replaced quickly.
2. Reduced Labor Costs: Ready mixed asphalt requires less labor than traditional paving methods. This saves money on both the initial construction cost and ongoing maintenance costs.
3. Fewer Environmental Concerns: Ready mixed asphalt contains fewer toxins and chemicals than other paving materials, making it safer for both the workers using it and the environment.
4. Resilience to Weather Conditions: Ready mixed asphalt is designed to resist weather conditions such as rain, snow, and heat. This makes it a good choice for areas that experience high traffic volume or severe weather conditions.
5. Durability: Ready mix asphalt is durable enough for use in high traffic areas, making it a good option for long-term pavement maintenance
Disadvantages of using ready mixed asphalt
Ready-mixed asphalt is frequently used as a pavement and road surface material. However, there are some disadvantages to using this type of asphalt. Here are three of the most common:
1. Ready-mixed asphalt often contains excess percolator fines, which can cause it to crack and crumble during use.
2. The batch size used in the preparation process can result in a slag layer that can reduce the life of the pavement surface.
3. Ready-mixed asphalt may also have lower quality than traditional asphalt mix because it is not compounded with other materials, such as bentonite or glass fibres, that can improve its performance.
How to mix ready mix asphalt
When mixing ready mix asphalt, it is important to follow the manufacturer’s instructions. The type of mixer, the ratio of sand to aggregate, and the temperature all play a role in achieving the desired result. However, there are some general tips that can help when mixing asphalt.
First, make sure the surface you are working on is clean and free from oil, grease or other debris. This will help reduce the chance of developing air bubbles in the mixture. Second, use enough water to ensure a loose slurry consistency. Finally, use a moderate speed setting with frequent agitation to avoid sticking and produce a smooth finish.
