Have you ever wondered what goes into paving chemistry? A significant amount of study goes into producing a suitable material for roadways. The chemical composition and molecular constitution of asphalt materials may be a little abrasive to most readers. We’re going to break down the essential components of asphalt and apply that paving chemistry knowledge. Eager to learn more? Then, read on!
Paving chemistry is a very important industry study. Think of the amount of roadway in the state of Florida alone. Chemists have worked to create a substance that not only can hold vehicles, but can withstand the elements as well. This substance is called asphalt. While it’s nearly impossible to make it last forever, the paving chemistry scientists are responsible for the longevity of your pavement. The science that produced a material than can withstand daily semi-trucks and UV abuse, allows you to perform daily functions. But, what are the common elements of asphalt? Let’s break it down.
From public roadways to private driveways, Level Pro has a paving solution for you. If you are in need of paving services, contact us today.
Common Elements In Asphalt
Asphalt is typically a combination of aggregates and sand. Aggregates used are a naturally occurring rocky substance that is a byproduct of petroleum processing. The name for this aggregate is bitumen, although it does not apply only to the asphalt process. Bitumen applies to dark solids with a specific chemical composition. Applied to paving chemistry, this is the leftovers of crude oil refinement and is actually mostly carbon.
Sand has been used as been used a binding agent for centuries. Tile has grout. Cinder block has mortar. Asphalt has sand. Asphalt is a fairly sticky substance. Sand is not only used as a binding agent, but also as a filler and binder. Think baking soda to the flour in cookies. Alone, the asphalt cannot perform as well. Without the sand to fill the space between aggregates and create a glue, asphalt would not hold together.
Breaking Chemical Bonds
Surely, there is more to asphalt than just rocks and sand. There is. Substances are applied to the compound at different points in time to make the asphalt stronger. For instance, when the sealant is applied to the surface of an asphalt parking lot. Generally, that sealant protects the asphalt from oxidizing and breaking down. Oxidizing disrupts the asphalt on a molecular level and can lead to crumbling or cracking. Other things than can harm asphalt are UV rays, oil, chemical spills, water and heat. Florida is known for its record breaking summer heat. The heat can warm the asphalt, speeding up the molecules in the compound causing it to soften. Rutting, a common damage happens after asphalt softens. This is how the roads end up with permanent drive grooves.
The Chemistry Down To The Atom
Of course, there is actual science that goes beyond what is talked about on this post. Hence, the molecular paving chemistry is best delivered by real chemists. Paving chemistry has served the asphalt business for over 150 years. According to this article, “The first bituminous mixtures produced in the United States were used for sidewalks, crosswalks, and even roads starting in the late 1860s.” That’s older than the car. With a science built upon laying foundations for the rest of the world to walk on, paving chemistry is more important than most people know.
