The Effects of Spring Showers on Your Asphalt Parking Lot

Spring has almost sprung and while April showers may bring May flowers they can also bring complications to your asphalt parking lot if you aren’t properly prepared.

There is a reason why our team at Sealcoating 2.0 recommends preventative maintenance when it comes to your asphalt surfaces. When these preventative measures protect your pavement, these spring showers shouldn’t cause you any problems. However, if you have failed to complete general maintenance, small cracks, potholes, and depressions can appear and ones that are already present could worsen and cause some serious damage.

How Does Rain Effect Your Asphalt Parking Lot?

To put it simply, water weakens the bond between your asphalt binder causing it to aggregate, or a material or structure that is formed from a loosely compacted mass of fragments or particles. When your asphalt surfaces have cracks it becomes extremely vulnerable to the elements, especially to water. With enough time water can slowly erode your unprotected asphalt parking lot, and weakening the supportive and vital structural layers of your pavement.

Virginia is known for experiencing all four seasons in a week which is ultimately not good for your parking lot. Standing water, which is very prevalent during the spring season, will go through the freeze and thaw cycle repeatedly. This works to shrink and expand water molecules, something that causes stripping which is the process of debunking the aggregate and binder. When the bond between the aggregate and the binder begins to deteriorate it weakens your asphalt parking lot which makes it more vulnerable to damage in the future. Once the water gets under the sub-base of your pavement it can even compromise the structural integrity of the pavement over time.

When this occurs and cracks are left untreated these small cracks will only start to become bigger and cause even more damage. Then before you know it, your asphalt parking lot will be filled with alligator cracks (cracks that resemble the scales on a reptile’s back or the cracking you’d see if you dropped a hard-boiled egg) leaving you with an unsafe and ultimately unappealing surface.

Not only are cracks important to look out for but like we mentioned above so is standing or pooling water because these puddles may be a result of surface depressions that are formed by sections of your pavement that is settling lower than the rest of the pavement. This means that a section of your pavement may have sub-base troubles which can be extremely dangerous.

During the asphalt parking lot installation process planning for proper water drainage is very important. When constructing parking lots and driveways our team takes the time to make the most out of grassy areas and inlets where water can be directed using slopes and asphalt curbing.

Porous pavement allows water from rain or snow to drain through the asphalt parking lot surface into the stone recharge bed and then filter back into the soil and groundwater below.
