How to Dispose of Asphalt for Recycling?

To dispose of asphalt for recycling, you can drop it off at an asphalt recycling center or arrange for a pickup by a collection and removal service. You can also rent a dumpster from us to dispose of your asphalt.

Types of Recyclable Asphalt

  • Porous Asphalt: allows water to penetrate and seep through the pavement, reducing the risk of flooding and enhancing water quality.
  • Warm Mix Asphalt: produced at lower temperatures, reducing energy consumption and greenhouse gas emissions.
  • Cold Mix Asphalt: produced and applied at ambient temperatures, eliminating the need for heating and reducing energy consumption.
  • Rubberized Asphalt: made with recycled rubber, improving pavement durability and reducing noise levels.
  • Reclaimed Asphalt Pavement (RAP): made by reusing old asphalt pavement material, reducing debris, and conserving natural resources.

How to Recycle Asphalt?

Recycling asphalt helps to conserve natural resources and reduce debris while also providing cost savings for pavement construction and maintenance. In this process, the old asphalt material is collected, crushed, and mixed with new materials to create a recycled asphalt mixture.

1. Milling

Asphalt milling is the process of removing a layer of asphalt from a paved surface, such as a road or parking lot, by grinding or cutting it away. The removed material, called “millings,” can be recycled and used in other paving projects or processed further to create new asphalt. Milling is typically done with specialized equipment that grinds the surface to a specific depth and collects the debris for disposal or recycling. This process can help restore a surface’s smoothness, levelness, and skid resistance, as well as extend the pavement’s lifespan.

The specialized equipment used in asphalt milling for recycling purposes typically includes a milling machine, which is a self-propelled unit equipped with a large rotating drum that grinds and removes the existing asphalt surface. These machines can vary in size and complexity, depending on the project’s scope and the type of milling required.

2. Stockpiling Asphalt Materials

When asphalt material is removed from the road and not used immediately, stockpiling of recycled asphalt becomes an essential part of the recycling process. It’s crucial to take great care when stockpiling recycled asphalt material to ensure the full benefits of comprehensive material testing are not lost. Depending on the variability found during testing, it might be necessary to build separate stockpiles of materials taken from different sections of a road. When each load arrives at storage, it’s important to record the details, including the type and amount of material, place of origin, and any undesirable contaminants. 

To prevent caking under the influence of generated heat, the stockpiled recycled asphalt pavement should not be piled higher than 3m. Additionally, asphalt scheduled for regeneration should either be covered with a layer of sand or kept under a roof to prevent water penetration. It’s also recommended to remove any 250 to 300mm crust that may form at the surface of the stockpile prior to recycling. Finally, to prevent any unauthorized dumping of other types of debris, it’s essential to ensure that storage areas or collection points are not accessible to the public.

3. Mixing Asphalt Millings in an Asphalt Recycler

The milled asphalt material is then mixed with new asphalt binder and aggregate in an asphalt recycler. The recycler heats the old asphalt material to soften it and then mixes it with the new materials to create a recycled asphalt mixture. The recycled asphalt mixture is then transported to the construction site for use in pavement construction. There are 2 main methods of asphalt recycling: hot recycling and cold recycling.

Hot recycling, also known as hot in-place recycling (HIR), is a process that involves heating the existing pavement to a high temperature (up to 350°F) to soften the asphalt. Once the pavement is heated, it is scarified and mixed with new asphalt and/or aggregate, then compacted to create a new, durable surface. This method is typically used for pavements with deeper structural damage and can be done with either a train or single-unit method. 

Cold recycling, on the other hand, is a process that involves milling off the top layer of the existing pavement and mixing it with new asphalt and/or aggregate at ambient temperatures. The new mixture is then laid back down and compacted to create a new surface. Cold recycling is typically used for pavements with less structural damage and is often used as a preventative maintenance measure. This method can be done on-site or off-site and can be further categorized as either in-place cold recycling or central plant cold recycling.

4. Screening and Sizing

After the recycled asphalt mixture is produced, it is screened and sized to ensure that it meets the required specifications for the pavement construction project. The recycled asphalt mixture is tested for various properties, such as strength, durability, and workability, to ensure that it will perform well in the final pavement structure.

Are there Other Methods of Recycling Asphalt?

Full-depth recycling (FDR) is a process of recycling an existing asphalt pavement into a new base layer, using the old pavement material as the primary component. FDR involves the pulverization of the existing asphalt pavement and the incorporation of an engineered binding agent or asphalt emulsion to create a new, strong, and durable base course layer. 

The process is typically done in place, eliminating the need to remove the old asphalt pavement, which reduces debris and the transportation of materials to and from the job site. FDR is commonly used on heavily traveled roads that require a strong and long-lasting pavement structure. The process has proven to be an effective and economical solution for rehabilitating deteriorated pavements while also providing a sustainable and environmentally friendly approach to road construction and maintenance.

How many times can asphalt be recycled?

Asphalt can be recycled an infinite number of times. With each cycle of recycling, however, the quality of the recovered asphalt could decline. The asphalt binder, an essential element of the asphalt mix, is breaking down, which is the cause of the asphalt's deterioration. The original asphalt's quality, the recycling process, and the circumstances surrounding the use of the recycled asphalt will all have an impact on how much the asphalt deteriorates. However, recycling asphalt is still an economical and environmentally responsible approach to reusing used materials.

Does recycled asphalt have better quality than newer asphalt pavement?

Depending on the recycling process used and the original pavement's quality, recycled asphalt may be of a similar or even higher quality than more recent asphalt pavement. Due to its more uniform composition and increased aggregate interlock, recycled asphalt can sometimes perform better than new asphalt in terms of durability when processed properly. It can also meet or surpass the same specifications as new asphalt. It's crucial to remember that not all recycled asphalt is created equal, and the quality might vary based on things like the sort of recycling process, where the recovered material comes from, and the number of impurities present. To ensure that the recycled asphalt satisfies the necessary requirements, it is crucial to hire renowned asphalt recycling facilities and carry out quality testing.

Can asphalt be recycled without moving it from a job site?

The quality of recycled asphalt pavement can vary depending on the specific recycling process and the materials used. Generally, reclaimed (recycled) asphalt can have similar or slightly lower performance characteristics compared to asphalt made from new materials. The Federal Highway Administration (FHWA) conducted a study that revealed how recycled materials might increase asphalt's sustainability and lessen its environmental impact. Moreover, according to a research paper, it was discovered that using reclaimed asphalt pavement (RAP) reduces greenhouse gas emissions by up to 25%. 3 Utilizing recycled asphalt can also help save natural resources by lowering the quantity of debris that is dumped in landfills.

Is recycled asphalt in demand?

Yes, recycled asphalt is in demand for various construction projects. In collaboration with the Federal Highway Administration (FHWA), the National Asphalt Pavement Association (NAPA) conducted an industry survey in 2018 discovering that more than 100 million tons of reclaimed asphalt pavement (RAP) were collected for reuse, saving about 61.4 million cubic yards of landfill space. According to the study, about 389.3 million tons of new asphalt pavement mixes were made in the U.S. using approximately 82.2 million tons of RAP and 1.05 million tons of recycled asphalt shingles (RAS). 4
