There is a lot of skill, preparation, and planning that goes into those perfectly-poured streets you drive on and sidewalks you walk on. If you are interested in asphalt or just want to learn something new, this short and simple asphalt paving guide is for you.
What Is Asphalt?
Asphalt is a combination of binder, filler, and aggregates, such as sand, gravel, and crushed rock. All of these components are mixed at an asphalt plant to create the material used for the asphalt pavement you see every day. Asphalt can be a hot mix, warm mix, or cold mix, depending on the temperature during production and the number of aggregates used in the mixture.
A little-known fact about asphalt is that is made up of nearly 100% recycled material.
How to Use Asphalt for Paving
There are several steps you have to take to lay asphalt correctly. While this process may seem in-depth, it’s necessary for a smooth, quality finish. The steps for proper paving work are:
Step 1: demolish and remove the existing surface using heavy machinery, such as forklifts, bobcats, and dump trucks. Fortunately, the broken up debris can generally be used to create new asphalt.
Step 2: grade and slope the area to make sure there is proper water drainage.
Step 3: prepare and test the sub base to make sure it can support the weight of the new pavement.
Step 4: pour the binder layer that will bind the new asphalt to the sub-base.
Step 5: install butt joints and transitions to make sure the new asphalt blends in with the surrounding asphalt, paving, or concrete.
Step 6: smooth and compact the entire surface, using a roller truck.
Each step in this process is essential to make sure the final result is smooth and long-lasting.
Tips for Better Asphalt Paving
During the paving process, it’s important to follow a few rules to make sure the pavement comes out problem-free. Some tips for better asphalt paving are:
Go slow and steady: rushing the pouring job can end up with a pavement full of bubbles and cracks. Slow and steady ensures a quality finish.
Use precise rolling: the final rolling should be done in precise movements to ensure a consistently smooth surface.
Hire a professional: asphalt work can be complicated so it’s best to hire a professional for any area that needs to be paved. Read more for information on hiring a pavement specialist.
