Ease of Use

The primary reason why this product is the go-to choice for small hole repairs in asphalt pavements is the ease of installation. There is no long, extended process of preparing or mixing materials. Instead, the air does most of the work. You simply pour the mix directly into the hole, compact it with simple manual tools (metal tamper or piece of lumber), and leave it to air dry. The mix turns into a permanent surface patch after extended contact with air.

The drying process, also known as curing, is very important to establishing a solid, stable surface that lasts a long time. If you want a permanent repair for your asphalt, you need to make sure the entire process is done correctly. If you want to speed up the curing stage of your pavement repair project, you can try a few recommended tips.

Use Gravel

You can use gravel to create a more dense space within the hole, which may help to establish lasting strength. Just fill the hole with gravel, little by little, while using your compacting tools to compress the gravel with each layer. Do not fill the hole all the way to the top; be sure to leave 2 inches of space below the surface line for your cold patch mix.

Pouring Your Mix

As you pour your mix, exceed the surface line by half an inch. This means that your mix should go over the top of the hole by a ½ inch. Then use your compacting tools to compress your material down until it is properly flattened. You may need to repeat this step two or three times to get a proper fill.

Expedited Drying

Asphalt cold patch mix cures by having contact with air. You can speed up the drying process by using hair dryers or commercial paint dryers. If you are going to use a hair dryer, you will need to manually operate it in a steady, sweeping motion to ensure even curing. The material is near dry when you cannot easily press into the surface with your hand.

Large-Scale Pavement Repair

For large-scale pavement repair jobs, you need a professional paving company. They have the training, equipment, and resources to provide dependable work in a convenient time frame. Be sure to choose a company that is licensed, bonded, and insured, and retains decades of experience in the road construction industry.

Your asphalt pavement is important to you. It was a significant investment intended to increase property value, safety, and curb appeal. So it is no surprise that you are interested in learning ways to enhance the appearance so that it looks the way it did the day it was installed. Whether you have an asphalt drive way or parking lot, the options for making it look better remain fairly the same. Continue reading to learn how you can make your asphalt pavement look like new again.

Asphalt Overlays

If your paved surface is old and faded, an overlay is a great investment. As long as the existing pavement is in good structural condition, a new layer of asphalt can be poured directly over it, rendering a fresh, brand-new paved surface. Not only are overlays efficient and cost-effective, they are long-lasting. If your paved surface is not structurally sound, you can get the same results by removing the old pavement and repaving the entire surface with new asphalt. These two options are the most invasive and significant investments, but they are worth the overall value you receive long-term.

Do-It-Yourself Tips

If you are not interesting in a pavement renovation, you can still benefit by implementing some do-it-yourself strategies to keep your lot or drive looking great. First, routine debris removal is important. This involves picking up trash and litter on a daily basis. It also involves prompt leaf and snow removal every season. Not only does this prevent unsightly stains, corrosion, and hazards, it makes the lot look clean and fresh. If you have a large lot or complex, it is wise to invest in a street sweeping machine to make this chore more efficient.

Preventative Maintenance and Repairs

Whether you choose to overlay your existing pavement, remove and repave your asphalt, or implement DIY strategies, preventative maintenance and fixing minor damages is a must. Catching small problems early on can save you money and maintain strong pavement. This includes crack filling, pothole repair, line striping and painting, grade repairs, drainage adjustments, and more. You must always be maintaining your paved surfaces, regardless of condition or square footage.

Sealcoating

Every paved asphalt surface should have a protective coating. Asphalt needs to be seal coated every 3 to 5 years, especially in regions that are hot and dry most of the year. This thin, clear protective layer shields harmful sunrays, which prevents it from prematurely fading, cracking, and more. It also creates a waterproof barrier that prevents corrosion, crumbling, heaving, and more.

The Difference Between Concrete and Asphalt Sealers

Paving contractors, road builders and even government agencies are turning to Roller Compacted Concrete as the pavement of choice in larger numbers as the acceptance of Roller Compacted Concrete, also known as RCC, grows across the United States. RCC offers unique qualities different from traditional concrete or asphalt that make the pavement an economical, fast-construction candidate for many applications previously reserved for asphalt or conventional concrete.

RCC has been traditionally been used for surfaces carrying heavy loads at low speeds because of its relative coarse texture, but in recent years RCC has been selected as the pavement of choice for a greater number of commercial and industrial applications. Cities such as Columbus Ohio have begun using Roller Compacted Concrete for residential streets, and Atlanta Georgia has used RCC for interstate shoulder construction. RCC is primarily used in the construction of industrial and commercial parking areas and low traffic road surfaces.

Typical applications of RCC include:

  • Industrial access roads and parking areas
  • Shipping yards and ports
  • Truck and freight terminals and distribution centers
  • Bulk commodity storage and compost areas
  • Aircraft parking areas
  • Urban, rural and park roadways
  • Large commercial parking lots
  • Temporary travel lanes

RCC is also being used in pavement systems for higher traffic speeds serving as base for traditional concrete or the lower lift in a two lift paving operation.

There are many benefits to the use of roller compacted concrete, but the main factor is the RCC can be constructed faster and cheaper than traditional concrete and multiple lift asphalt pavements. RCC can be constructed fast because it is typically placed with asphalt type paver equipped with a standard or high density screed, then compacted with rollers. Unlike conventional concrete the use of forms, dowels, reinforcing steel and vibration are not used. Additionally transverse joints are not required, however when project specifies they must be present the joints are spaced farther apart than conventional concrete.

The cost savings associated with RCC is attributed not only to the ease of construction, but the material also uses less Portland Cement the most expensive ingredient in conventional concrete. The specific savings associated with the use of roller compacted concrete is dependent on the complexity of the construction, size of the project and specified mix design.

Additional benefits of RCC - Roller Compacted Concrete

  • Durability and resistance to chemical attack
  • High freeze-thaw durability even without the use of air entrainment
  • High strength capable of supporting heavy repetitive loads without failure
  • Reduced cracking and shrinking
  • Rigid surface eliminating rutting except in areas of heavy tire chain or studded tire use
  • Resists abrasion even under heavy traffic loads and volume
  • Light colored surface reduces the required lighting for parking and storage areas
  • Light vehicles and cars can travel on RCC soon after completion

While the benefits of RCC are numerous it is important to understand there are also some limitations to the use of roller compacted concrete. For example the production of large quantities of RCC requires specialized equipment. While a transit mix truck can mix RCC the mixing time is significantly longer than conventional concrete and the amount of RCC than can be mixed in the truck is reduced because the dryness of the RCC mix. Also the surface of RCC may not be suitable for high speed traffic without diamond grinding.

Other limitations of RCC

  • Adjacent slabs and multiple horizontal lifts must be place within an hour to ensure good bonding unless a cold joint is planned
  • Pavement edges are more difficult to compact causing most specification to require 96% modified proctor density on cold joints
  • Admixture usage on RCC may be higher than traditional concrete because of the dryness of the material
  • RCC paving in hot weather requires extra attention to reduce the possibility of water loss and evaporation

When considering the versatility of RCC, its ease of application in comparison to conventional concrete and its durability as compared to asphalt it becomes clear the roller compacted concrete is a suitable paving substitute. When considering the rising cost of oil and petroleum based products such as asphalt it becomes clear that RCC is likely the paving material of the future.
