Asphalt is used to pave roads, parking lots, driveways, and more. But even durable asphalt doesn’t last forever. With proper maintenance, an asphalt parking lot can last over 30 years, according to Angi. In this post, we’ll look at how asphalt deteriorates over time and the common problems that require asphalt repairs.
Environmental Factors Cause Damage
Environmental factors like sunlight, heat, freeze-thaw cycles, and tree roots all damage asphalt over time. Sunlight and heat dry out the top layer of asphalt, causing surface cracks in patterns called alligator cracking. In colder climates, water seeps down into asphalt and expands when it freezes, creating cracks. Expanding tree roots crack and shift the asphalt as they grow larger underneath it. Additionally, plain old wear and tear from vehicles driving on it every day also grind the asphalt down over time.
Base Layer Problems Are Significant
While the top layer of asphalt takes a lot of abuse from the elements, problems in the base layers underneath cause even more significant damage. The base is usually made up of stacked layers of stone aggregate and sometimes a layer of concrete. If these get compacted unevenly, if water pools under the asphalt due to inadequate drainage, or if the base shifts or settles, it affects the quality of the asphalt pavement on top. This can create divots, cracks, and uneven surfaces that require extensive asphalt repairs.
Signs Repairs Are Needed
Cracks that are 1/4 inch or wider, potholes, ruts, divots, depressions, uneven surfaces, and standing water that doesn’t drain are all common signs your asphalt needs repairs. If you notice these warning signs, it’s time to call in asphalt repair experts to fix the problems before they spread and worsen. With proper asphalt maintenance and timely repairs when needed, you can extend the lifespan of any paved surface.
DIY Repairs Aren’t Enough
While you may be tempted to try quick DIY fixes like filling cracks with sealant yourself, this is just a temporary patch. Without addressing the underlying problems, new cracks and issues will continue to appear. Professional asphalt contractors have the right equipment, materials and expertise to fix the root causes and properly repair your asphalt.
