As leaders in the St. Louis asphalt industry, we feel it is our duty to provide more than just great paving solutions, but knowledge that everyone can utilize in preserving their parking lot. While asphalt is tough in nature, it will develop cracks over time. Unfortunately cracks are completely unavoidable; however they can be easily repaired.
In this blog entry, we explain exactly what goes into the repairing process.
#1 Clean the Surface: It is extremely important we clean any loose debris that sits within the cracks. Once we loosen all the broken asphalt using a heat lance or abrasion wheel, we will go over the infected area with a high pressure blower or power broom to remove any loose material.
#2 Fill the Cracks: We use hot applied rubberized crackfill material specifically designed for cracks in asphalt surfaces. This type of material is heated in large double wall burners and is usually only available to professionals in the asphalt industry. The proper material and equipment makes all the difference in preserving your asphalt surface.
#3 Let Dry: Crackfilled areas can be opened to traffic in a relatively short period of time. We do not recommend applying crackfill material in current weather conditions as the material will not set up properly and will remain “tacky” to foot and vehicle traffic. One of our pavement professionals will explain the necessary drying period before the project is completed.

Even the most well-designed asphalt pavement system can’t escape the damaging effects of Mother Nature. How can facility owners or building managers know which preventative maintenance strategies are best for them?
In relatively new pavement showing the beginning signs of deficiencies such as surface cracking, preventative maintenance can add years to the life of an asphalt pavement system. Planning a pavement maintenance program early on can save both time and money.
Here are some helpful processes for maintaining your commercial asphalt system:
Crackfilling – Crackfilling typically refers to the process of blowing out and cleaning cracks prior to installation of a crackfiller material. This is also known as the “blow-and-go” method. If properly done, crackfilling reduces the infiltration of water into the crack, which protects the pavement system from being weakened by moisture. Crackfilling should be used for wider-type, non-working cracks.
Cracksealing – The cracksealing process involves an additional step that’s highly recommended for longer-term performance, and involves routing of the crack. Cracksealing includes grinding out the crack to a wider, 0.5-inch by 0.5-inch to 0.75-inch by 0.75-inch square, providing a reservoir for the rubberized crackseal material.
Surface Treatments – There are many surface-treatment options to choose from. General categories of surface treatments include: coatings (asphalt or coal tar emulsions), penetrating or rejuvenating sealers or aggreagate-based seals such as slurry seals, chip seals and micro-surfacing.
Be sure to call Leritz / Busy Bee to inquire if any of these practices will work for your commercial pavement system!
