The solution for a highly deteriorated driveway is the installation of asphalt millings, which are usually carried out through machines called planers or milling machines.
Milling machines fragment the driveway layers to the desired depth. These machines use a rotating segment to go deeper and reach the surface to be treated.
Asphalt millings prevent many problems related to drainage and asphalt resurfacing. This process removes the topmost layer of asphalt before putting a new layer. In this way, you prevent your driveway asphalt from going too high after consistently resurfacing.
Asphalt millings also allow reusing the topmost layer for other projects. In other words, you recycle the asphalt layer you removed. Generally, homeowners use this recycled asphalt to resurface the driveway or replace stone gravel.
Asphalt millings are very resistant to harsh weather elements and are more cost-effective. In this article, we’ll be talking about the advantages and disadvantages of asphalt millings, recycled asphalt, crushed asphalt, and recycled asphalt driveway.
Advantages of asphalt millings
– Asphalt millings allow recovering asphalt for recycling operations.
– You don’t need to burn asphalt bitumen. This will eliminate unwanted emissions.
– Once the old asphalt is removed, it doesn’t lose its homogeneity and can be mixed, handled, and transported.
– You can get your driveway resurfaced in one day.
– The procedure removes deteriorated layers that can cause problems in the future.
Disadvantages of asphalt millings
– Damage by foreign objects in the vehicle is frequent
-Its application is limited only to strictly solid surfaces.
-They can affect the depth of fixed internal reinforcement structures.
-Significant increase in fine particles produced by the friction of the teeth against the pavement.
-Excessive wear of teeth and frequent replacement which results in expenses
Mastic asphalt is a construction material for roofing and driveways, which stands out for its resistance to weather conditions. It is one of the most common asphalt millings. It can be even used for flooring and roofing tasks. This asphalt melts in very hot temperatures.
Mastic asphalt is not permeable, so it doesn’t let water seep through. This distinguishes mastic asphalt from other flooring and paving materials. Putty versions of mastic asphalt withstand moisture.
This is the other name or term we use for asphalt millings. Crushed asphalt and recycled asphalt are the same and have similar applications. Crushed asphalt is used to replace gravel pavement in entryways and driveways.
Crushed asphalt adds elements that make it more resistant to wear and foot traffic.
Why crushed asphalt driveways are a great idea
Using asphalt millings in driveways is a home renovation idea that is gaining popularity. Despite this, asphalt millings are not perfect, they have disadvantages. We’ll focus on the pros first.
Installing a millings driveway is definitely cost-effective. They use fewer materials and resources and are less polluting than other paving materials.
While asphalt millings may not resist heat as well as other paving materials, they resist snowfall and heavy rain very well. Their porous surface prevents water from stagnating after heavy rain.
Besides their permeability qualities, asphalt millings do not allow dust or dirt to settle on the surface for long. This asphalt contains tar.
Asphalt millings look like gravel. Crushed asphalt gives the driveway a modern and classy look. That’s the reason most homeowners prefer this choice for their entryways.
Recycled asphalt is the combination of second-hand asphalt with virgin materials to create a durable and appealing mixture for roofing, paving, and resurfacing. This aggregate looks quite the same as concrete. According to the Main Roads WA State, over 10% of the households have a recycled asphalt driveway.
Certainly, not only do homeowners benefit from this kind of asphalt millings but landscape contractors also do. This material is very common in the construction of driveways and entryways because it lasts and because of its capacity to prevent flooding. Creating a crushed asphalt driveway does not cost a lot of money either. This aggregate can also be found in many walking trails and bike paths nowadays.
Impressively, these asphalt millings can be installed cold, differentiating them from other flooring materials.
Benefits of recycled asphalt
Recycled asphalt is money-saving. Since recycled asphalt derives from a mixture of recycled materials, contractors and manufacturers do not need to excavate natural resources. This reduces the cost of asphalt millings considerably. Plus, It is eco-friendly and few raw resources are required for the manufacturing process.
Because of this, landfills collect less asphalt and non-biodegradable asphalt waste. Recycled asphalt is also lighter than raw asphalt.
Issues to consider with Recycled Asphalt
This asphalt has some issues.
Less choice in color
It doesn’t look exactly like black asphalt, however; it works in the same way and lasts as long as the virgin counterpart. Asphalt millings can be gray and brown, but never black. They lose part of their coloration because of the carbon loss. Anyway, if you want a black driveway, asphalt millings may not be what you are looking for.
Alternatively, you can lay red asphalt. The problem with this aggregate is that stocks are almost empty, which makes it challenging to find them in online stores.
Variance in Quality
Not all asphalt millings are top quality. There are actually many companies selling low-quality asphalt millings. To avoid this, go through reviews to make a decision. Choose a company with years in the driveway paving field and a good reputation. Make sure the company complies with the minimum standards of quality and is locally owned.
Why not gravel paving
Unlike gravel driveways, asphalt millings do not scatter over time and stay in place. While asphalt millings keep driveways high enough, gravel reduces the depth of the driveway over time. On top of that, asphalt millings do a better job filling potholes.
In addition to that, asphalt millings are easier to plow than gravel. Also, asphalt millings do not get ruts easily. Millings driveway gathers less dust than most gravel driveways. As a result, many contractors recommend asphalt millings over gravel.
