What Are the Different Types of Asphalt Paving Jobs?
Asphalt is well-known material which is used to cover roads. It is a natural material found in crude oil and natural deposits, usually around bodies of water and oil sands. This can come in liquid or semi-solid form, and is characterized by its viscosity and sticky, black appearance. It consists of bitumen, which is something composed of PAHs or polycyclic aromatic hydrocarbons.
The 2 kinds which are used in asphalt paving construction are mastic and rolled. Rolled is the one most people are familiar with, as it used about 80% within the U.S. It is made from aggregate, or with materials like gravel, sand, or recycled concrete, using an asphalt binder. This kind is used on roads, asphalt paving and parking lots, it is applied in layers, after which will be compacted. Different kinds are distinguished with the process that is used, in order to bind the aggregate and asphalt.
Hot mix asphalt concrete is created using temperatures in excess of 160°C. This serves to reduce viscosity and moisture, which means the end result is an extremely durable material. And is used mostly in high-traffic areas, like airports and busy highways.
Warm mix asphalt concrete reduces temperatures needed for manufacturing, by adding such things as zeolites, emulsions and waxes. A reliable paving service will benefit the environment and workers, due to the fact it uses less fossil fuel and fume emissions. With a cold mix, the asphalt will be emulsified using soapy water, before it is mixed with aggregate, which means no high temperatures will be needed. But, the resulting material is not as durable and is used in low traffic areas.
