asphalt, black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid. It is obtained either as a residue from the distillation of petroleum or from natural deposits.
Many types of asphalt exist, but they all have one common goal: to provide a durable and weather-resistant surface for roads, parking lots, and freeways. Below we’ll look at the different types of asphalt, what each type is made of, the pros and cons of each, and the best-use applications.
Although it's most often associated with roads, asphalt is used for many purposes, though roads account for its most extensive use. Of the more than 2.7 million miles (4.3 million kilometers) of paved roads in the U.S., 94 percent are surfaced with asphalt, according to NAPA.
Whether you prioritize cost-effectiveness, environmental considerations, or specific performance attributes, the following insights into different types of asphalt will guide you towards making the most informed decision for your surfaces.
Asphalt is much more than a black, sticky material used for paving. Its unique composition and wide range of uses make it a cornerstone of modern infrastructure. From roads and highways to parking lots and roofs, asphalt’s versatility and durability have cemented its place in construction.
Asphalt is frequently used for patching and repairing damaged sections of roads, parking lots, and other asphalt surfaces. It allows for efficient and cost-effective maintenance to extend the lifespan of existing asphalt pavements.
An asphalt mix—often referred to as asphalt concrete—is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. It consists primarily of aggregates, binder, and filler that are mixed together in precise proportions.
Asphalt is a sticky, black, semi-solid form of petroleum used to bind aggregate together. A versatile material, asphalt creates a smooth, durable surface for driveways, walking paths, roads and parking lots, which is why it’s nearly everywhere you look in American communities.
Main uses of asphalt. The most recognized use of asphalt is in the construction of roads and highways. Thanks to its ability to create a smooth and durable surface, asphalt is ideal for all types of roads, from small roads to large international highways.
Asphalt provides exceptional adhesion, durability, waterproofing, and elasticity. This elasticity is especially important as fluctuations in temperature can cause roads to expand and contract. Besides road construction, asphalt is used in the roofing industry because of its weatherproofing abilities.
