One of the most affordable and convenient methods for small-scale asphalt mending projects is to use a cold patch mix. Many property owners will tell you that this approach saves money, Asphalt And Paving Companies Near Me in Boksburg and can reduce the amount of labor required for the job, making it a great solution for small holes in parking lots, walkways, streets, and driveways. However, the process of cold asphalt patching can be accelerated with the right application techniques, saving property owners some time too! Customers, clients, guests, and occupants can use the pavement in the same day!
Continue reading to learn some great tips on how you can shorten the amount of time it takes for the cold patch asphalt mix to harden, and drastically cut down on turnaround time, from project start to finish.
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.
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.
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.

Explaining Tire Scuff Marks on New Asphalt Pavement
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.
