Asphalt is one of the most common paving materials and is used to help with drainage and traction. We all come into contact with asphalt every day of our lives. But have you ever stopped to wonder what asphalt even is? Well, I suppose if you have, you found this blog post. So, without further ado, let’s answer all the questions you have about asphalt.

What is asphalt?
Asphalt is a mixture of sand and gravel that is used to pave roads, parking lots, and driveways. The asphalt mixture is heated and then poured over the surface of the pavement. The heat from the asphalt causes it to set and harden into place.
Asphalt paving is a common choice for many people because it provides smooth surfaces for vehicles to travel on, making for safer roads overall. There are some drawbacks to using this type of material as well: It can be messy during installation since it requires heating up before pouring into place; when first installed there may still be seams between sections; when applied incorrectly asphalt will often crack due to expansion or contraction in different seasons; if left untreated asphalt will start deteriorating after only 10 years under normal conditions such as rainwater runoff or car exhaust fumes from passing vehicles which cause them to oxidize faster than normal concrete surfaces do (which last up 30+ years).
What is asphalt made of?
Asphalt is a mixture of sand, gravel, and petroleum. The basic components of asphalt are petroleum, sand, and gravel. Petroleum is the most common ingredient in asphalt because it can be refined into liquid form for use in construction projects like roads and driveways. Sand and gravel are used to help bind the asphalt together by holding it together with its sticky nature.
How is asphalt made?
Asphalt, like most concrete and masonry materials, is manufactured by heating and blending its ingredients. The first step in this process is called curing: the asphalt is heated to about 350 degrees Fahrenheit (180 degrees Celsius) so that all of its building materials will have time to fully combine into one solid substance. Curing takes approximately one hour per every 1,000 pounds of asphalt being processed.
After curing, mixers (also called “tumblers”) are used to blend all of the ingredients together at a high speed until they become homogenous. Once mixed properly, this mixture is poured into molds—typically made from steel—and allowed to cool before being removed from those molds and transported elsewhere for use as construction material or decoration wherever required.
What is it used for?
It is a common material used in paving projects. It can be used for roads, parking lots, and walkways since it is waterproof, flexible, and durable. Asphalt is also cost-effective because it lasts a long time, so you won’t have to replace your paving project as often as you would if you used other materials like concrete or brick pavers.
What are the 3 types of asphalt?
There are three main types of asphalt: Hot Asphalt, MC Cold Mix, and UPM. There are also different varieties of these asphalts for summer and winter use.
Are old tires used in asphalt?
Recycled tire rubber (RTR), from waste tires (Figure1), has been used in asphalt by the paving industry since the 1960s.
What is the difference between asphalt and bitumen?
Bitumen is the liquid binder that holds asphalt together.
