What is an Asphalt Pavement?

Stone (aggregate), sand, additives, and liquid (petroleum) asphalt are the main components of asphalt pavement. Asphalt pavements at asphalt paving Seattle are bound together with liquid asphalt, a gooey, black substance. It is naturally dense and also comes in semi-solid forms. Bitumen is yet another common name for asphalt.

Cold Mix

Cold mix asphalt is a versatile type of pavement used for construction, road repairs, and other applications. This type of paving is environmentally friendly and easy to use. In addition, it does not require high-tech equipment to mix the product, and it is a cost-effective option for construction projects.

A study conducted in Finland examines the performance of a Finnish version of this pavement. The Finnish version is known as oil gravel, and it will be tested on a low-volume road in Minnesota in 1995. Researchers will assess the material’s suitability for use in the United States and the mixing requirements.

Cold-mix asphalt pavement can be used on various surfaces, including roadways, parking lots, and driveways. However, it cannot be used at under forty-five degrees Fahrenheit shells. Once cured, cold mix asphalt pavement can be sealed with a top coat. The top coat should be applied between one and 1.5 inches deep.

The process of cold mix asphalt pavement construction begins with the preparation of the site. This stage involves separating dirt and rubble from the mix. Removing dirt is essential because it promotes poor bonding between the asphalt and aggregate. Moreover, it can cause the subsequent paving composition to deteriorate quickly.

Coarse Graded

Coarse-graded asphalt pavement is composed of aggregates less than 2.36 mm. It is applied by hand or by using appropriate mechanical equipment. The maximum aggregate size of this mixture is about one sieve size more significant than that of NMAS. In the UK, hot-rolled asphalt is often used as a surface layer.

The grading of this pavement depends on several factors. One factor determining the finished pavement’s quality is its resistance to flexing. The resistance value measures the pavement’s resistance to flexing. It is the most suitable material for roads that see heavy traffic. It can withstand high-speed braking and heavy-duty vehicle applications.

This type of asphalt mix is usually used for surface courses that are 20-30 mm thick. Its high stiffness and resistance to deformation make it the preferred choice for secondary roads in Nordic countries. Its high workability and low cost of production offset its higher production cost. It also provides a smoother, quieter surface.

Coarse-graded asphalt has a higher density of aggregates than fine-graded asphalt. It contains more coarse particles than fine-grated asphalt and is therefore superior for pavements with rutting.


Although blacktop and asphalt are sometimes used interchangeably, there are many differences between the two types of pavement. They share the same components but are mixed differently, and each has a different purpose. In addition, they come in different grades. If you’re interested in a blacktop driveway, you might want to learn more about it.

Blacktop contains crushed stone and bitumen, a dense black compound that comes from petroleum distillation. This material is then heated to around 300 degrees. Because of its higher stone content, it is very durable. It is often a good choice for driveways, parking lots, and other residential roads.

Asphalt pavement has several advantages over the blacktop. It is a harder surface than other types of pavement and retains heat more effectively. This makes it a safer choice for wintertime travel. Additionally, asphalt is more impervious than different types of pavement, which means it will not be damaged by rain. In addition to paving roads, asphalt is used for airport runways, cable coatings, and reservoir and pool linings. It also acts as a sound-proofing material.

Before installing the blacktop, check out some examples of blacktops. You can also visit a completed driveway to get an idea of how the finished product looks. Look at the finish and the size of the stones in the mix. Then, decide on the type of finish that you want for your driveway and have your contractor match the material with the finish you want.
