When city streets wear down and need to be redone, construction crews enter the scene and remove old layers of asphalt before applying new layers of asphalt. It’s easy to assume old asphalt is useless and simply gets thrown out, but old asphalt (aka asphalt millings) can be reused on another project.
Recycled asphalt is ground down into aggregate size, at which point it is capable of hardening and binding together. This creates a cost-effective option for a base or sub-base material. To produce a sufficient finished product, the asphalt must be uniformly applied and compacted with a roller.
Cost – Most of the time asphalt millings are considered recycled asphalt. They are asphalt from previous projects that have been crushed into gravel sized pieces. Because there are not new materials going into the creating of this gravel the cost is often much less than gravel coverage.
LEED Certified – because this is a recycled material asphalt millings are a long lasting, Eco-friendly material that can help you with your project’s LEED certification.
No Maintenance – Because the milled asphalt is crushed, like gravel surfaces it does not require maintenance such as resurfacing. Milled asphalt actually hardens over time becoming stronger than when it was first installed.
Weather Friendly – Because the milled asphalt it crushed the dangers of freezing and thawing that winter brings normally damaging other options are no longer an issue for a property owner.
If you are trying to save money and care about reducing your ecological footprint, you might want to consider using asphalt millings to pave surfaces. By adding asphalt millings you’ll enjoy the combined benefits of asphalt and gravel surfaces.
If you like the eco-friendly ideology behind asphalt millings, but you’re not sure they’re right for your project, you might want to consider using hot mix asphalt made from a percentage of recycled materials.

#1. Asphalt Millings are Cost Effective
The biggest advantage to using recycled asphalt is saving money. Recycled asphalt requires fewer raw resources than new asphalt, saving you money from the get-go. Asphalt contains oil, and so when gas prices go up so does the price of new asphalt. When gasoline prices reach their peaks, asphalt millings become even more attractive.
#2. RAP = More Eco-Friendly
Since new materials don’t need to be produced, the process is more environmentally friendly. Plus, since asphalt is non-biodegradable, it’ll go to waste if it is not reused. When old asphalt is tossed into a landfill, it sits there indefinitely taking up lots of space. By reusing asphalt, you can reduce the amount of junk littering landfills.
#3. It Holds Up Surprisingly Well
It’s easy to assume that recycled asphalt will not stand up to the elements all that well, but in fact, RAP typically stands up to pooling, flooding and snow with impressive strength.
#4. It’s Uniquely Good Looking
RAP doesn’t have to look like a bunch of random asphalt chunks roughly tossed together. RAP surfaces, when done right, can look really good. They do not look exactly like asphalt, instead they offer a cross between gravel and asphalt surfaces.
#5. Great Bonding Material
Recycled asphalt contains tar, which helps it bond better than other loose-fill materials. With proper moisture and compaction, recycled asphalt bonds well enough to create a semi permanent driveway surface that sticks in place and reduces dust and dirt.
