Why Do Asphalt Repair Patches Fall Apart? The Top 3 Reasons

If you’ve ever had asphalt repair done on your property, you know how frustrating it can be when the patch falls apart shortly after installation. There are several reasons why asphalt patches may fail, but today we’re going to focus on the three most common ones that are poor materials, non-adhesive surfaces, and moisture damage.

Poor material or bad mix:

Poor materials are one of the most common reasons why asphalt repair patches fail. Your paving solution’s quality is crucial. The quality of your asphalt mix directly influences how long it will last and how well it will withstand the elements and its frequent use over time. If the asphalt mix is of poor quality, it will not adhere properly to the surface and eventually crumble and fall apart. To prevent this, use only high-quality asphalt mix for your repairs.

Quality control begins with collecting and processing aggregate materials to produce the finest quality asphalt. All aggregated materials utilized in asphalt repair patches must be durable to withstand early wear. Different sized aggregates must be utilized to create the best surface, and all aggregates must be tested against numerous stringent requirements to assure quality.

Great asphalt contractors such as Action Construction Asphalt & Concrete stay on top of the newest technological advancements and adhere to strict quality control standards.

Non-adhesive surface or lack of adhesion agents:

Another common reason for asphalt patch failure is a non-adhesive surface. This means that there is nothing for the asphalt to bond to, resulting in a weak and unstable patch. To avoid this, make sure the surface around the repair is clean and free of debris before applying the asphalt mix.

The asphalt binder is significant in road building as it permanently binds aggregates of various compositions and particle sizes. As the asphalt binder lacks sufficient adhesiveness, bare grains may surface after a while. This causes the grains to gradually separate from the asphalt layer, resulting in potholes in the pavement. Adhesion promoters, often known as adhesive agents, are useful and effective promoters in practice. They are polyamide-based compounds that should improve the adherence of the asphalt binder to the aggregates, enhancing the asphalt mixture’s lifespan and resilience to mechanical strain.

Moisture damage:

The third most common cause of asphalt patch failure is moisture damage. When water infiltrates the asphalt patch, it causes repair failure of hot-mix asphalt pavements, usually due to a lack of adhesion between the asphalt binder and the particles. A lack of adhesion can induce stripping of the asphalt covering from the aggregate.

Moisture damage to asphalt repair patches leads to a variety of problems, including cracking, potholes, and other issues. Other forms of damage or strain, such as rutting and fatigue, are influenced by the durability or integrity of moisture damage.
