What are the benefits of asphalt pavement?

  • Asphalt is 20-40% cheaper than concrete.

  • It is safe, economical, and the most long-lasting and durable paving material.

  • Asphalt pavement is 100 percent recyclable.

  • Asphalt pavements provide the user with a smooth, quiet, safe ride surface.

  • Properly designed, built, and maintained asphalt pavements enhance vehicle safety by providing a renewable, skid-resistant surface.

What is the Difference Between Asphalt and Concrete?

Asphalt & concrete are two construction materials which are commonly used around the world. The primary difference between the two is that asphalt is made by mixing aggregate with bitumen, a sticky black hydrocarbon which is extracted from natural deposits or crude oil. Concrete is made by mixing an aggregate material with a cement binder & then allowing the mixture to harden, forming a rock-like substance. Asphalt is used for different construction tasks, ranging from roofing to driveways, footpaths, roads etc. Concrete is applied cold and a combination of cement, rocks (sometimes–aggregate) and water. Concrete is a harder substance and will not soften up with high temperatures. Asphalt will become more soft and pliable under high heat. An easy way to remember the different between asphalt & concrete is that asphalt is usually black to brown in color, & has a distinctive texture, while concrete is greyish in color & looks more like rock.


How long will my pavement last?

The success of your pavement depends on three factors:

  1. Thickness and type of pavement installed.
  2. Thickness and type of sub-grade (crushed rock) provided. Based on the material type the contractor/engineer can determine the strength coefficient with sub-grade to support a given pavement. Lower ratios require thicker cross sections of pavement to support the pavement and provide appropriate longevity.
  3. Frequency and type of traffic driving across a given pavement section will impact performance and longevity. Remember, one heavy duty loaded truck driving across that given section of pavement is the equivalent of 10,000 cars driving across the same section of pavement! These variables will impact longevity of pavement and are critical in building or maintaining your pavement in a satisfactory condition.


What can be done about cracks?

Crack filling will be done in advance of the seal coating process. In general, only seam-line cracks exceeding one-quarter inch will be filled, but this will be specified in the bid proposal. The asphalt sealer can adequately fill tiny cracks. We use a product called Dura-fill Heat Stabilized Crack Filler, which is heated to roughly 400 degrees, at which temperature it can be poured into the exposed joint or crack. It will cool and harden inside the crack, preventing moisture penetration. Affected cracks will be cleaned appropriately prior to being filled with either manual or motorized brooms and/or compressed air. Extended cracking or “gator areas” should be repaired with asphalt hot mix, not rubberized crack filler.


What type of prep work is required for asphalt sealing?

To ensure the best coverage, the asphalt surface must be clean of dirt, oil spots, moss, and any other debris prior to sealing. Most surfaces can be cleaned with wire brooms and with a device called a Powerbroom, which is similar to a weedeater with circulating bristle heads. Once the necessary debris is dislodged from the asphalt surface it will be blown clean with the high-powered backpack blowers and/or Billy Goat parking lot cleaning equipment. A pressure washer will be used on rare occasion when moss is particularly heavy. Pressure washing must be done in advance of the seal coating process to allow time for the water to dry.


When is it too cold to place concrete?

It depends. Normal concrete will not set or harden when the concrete temperature is below about 35F. Many times specifications will say something like “Concrete may not be placed when the temperature is 37F and falling.” With heated water and aggregates, accelerating admixtures, and other methods, jobs can be placed below freezing, but it is more expensive. In most southern states there are so few freezing days that it is not worth it to try to place concrete when the temperature is below freezing.


When is it too hot to place concrete?

It depends. High temperatures (90F and above) cause concrete to set or harden faster. High temperatures also can reduce the ultimate strength of concrete. Strong winds and low humidity can also cause problems with plastic shrinkage and drying shrinkage potential, even at moderate temperatures. To avoid these problems, planning, timing of the finishing operations, proper use of retarding admixtures, and proper curing are necessary.


What is architectural/decorative concrete and how much more does it cost? 

There are many types of colored and stained concrete: Some with simple texture, some with unique patterns, some with color only and no texture. The cost may vary from $1.00 – $7.00 additional per square foot. Denver Asphalt LLC has been doing decorative concrete for about 8 years now.
