Asphalt is one of the prevalent recycled materials on roads, driveways, and parking lots. 3/4" recycled asphalt significantly reduces the project cost and is also environmentally friendly. Many questions arise about the properties and use of 3/4" recycled asphalt. This article answers three commonly asked questions about 3/4" recycled asphalt.

1. How Is 3/4″ Recycled Asphalt Hardened?

The first step to hardening 3/4" recycled asphalt is to mix the old asphalt with hot bitumen and recycled filler materials like rubber. Then, experts prepare the project surface to form a stable and well-compact ground. Once the 3/4" recycled asphalt is laid on the prepared surface, a combination of light and heavy rollers compact the materials.

After the rollers shape and compact the 3/4" recycled asphalt, dust of calcium carbonate powder gets added to harden the surface. The calcium carbonate reacts with the bitumen added in step one, which heats up to fill the void in asphalt. When the asphalt cools down, the surface becomes rigid and compact.

2. How Do You Maintain 3/4″ Recycled Asphalt To Increase Lifespan?

Part of the maintenance to increase the lifespan of a 3/4" recycled asphalt is DIY, while the other calls for expert help. For instance, you could sprinkle calcium carbonate powder to harden tarred surfaces. Also, remove any weeds on your asphalt surface to prevent damage to the 3/4" recycled asphalt substructure.

You will still need a professional to reseal the surface at predetermined intervals to prolong life. The sealant repairs minor issues and boosts the compactness of 3/4" recycled asphalt to enhance durability. If your surface has any cracks, the expert will open up the cracks and add freshly mixed 3/4" recycled asphalt.

3. Can You Resurface 3/4″ Recycled Asphalt With New Asphalt?

In some cases, you can resurface 3/4" recycled asphalt with new asphalt to give the project surface better long-term results. Nonetheless, the choice depends on the quality of the recycled materials and the standard of workmanship. For example, you won't need to add new asphalt to 3/4" recycled asphalt if you get quality materials and labor.

Situations that may call for a layer of new asphalt include the appearance of low areas and potholes after you sweep and remove waste from the surface of your driveway or parking lot. In addition, consider using a new asphalt addition when you bind the recycled surface into large parts with a lot of loose material.

The ideal way to determine whether you need a new layer is to get the guidance of a professional asphalt pavement service such as Boulder Recycled Aggregate.

Asphalt can be recycled multiple times and still maintain high quality at a lower price. So, you would never go wrong with 3/4" recycled asphalt. Besides, as long as you keep up with the standard maintenance, you'll get the maximum life expectancy.
