Asphalt pavement is durable, but over time, it can develop various forms of damage. Identifying these distresses early is essential to prevent costly repairs and ensure roads remain safe for vehicles. At Road Doctors, we specialize in repairing asphalt with spray injection patching services in Central Texas, and we provide equipment for this purpose. In this blog, we’ll discuss how to identify common asphalt pavement distresses and how addressing them quickly can extend the lifespan of your roads.
Cracking
Cracks in asphalt are one of the most common forms of pavement distress. Cracking can be caused by a variety of factors including weather conditions, poor drainage, and heavy traffic. There are different types of cracks to look out for:
Alligator Cracking: These are interconnected cracks that resemble the scales of an alligator. This type of cracking indicates structural failure and usually requires immediate attention.
Longitudinal and Transverse Cracks: These cracks run parallel or perpendicular to the road’s centerline and are typically caused by temperature fluctuations and shrinkage in the asphalt.
Edge Cracks: These appear along the edge of the pavement and are often caused by poor drainage or lack of support from the shoulders of the road.
If left untreated, cracks can allow water to penetrate the surface, weakening the base and leading to larger issues like potholes.
Potholes
Potholes form when water seeps into cracks, freezes, and expands, breaking up the pavement. Over time, vehicle traffic exacerbates the damage, and chunks of asphalt are dislodged, forming a hole in the road surface. Potholes are a safety hazard, and they can cause significant vehicle damage if not repaired quickly.
Spray injection patching is an effective solution for filling potholes, providing a durable and long-lasting repair that withstands heavy traffic and harsh weather conditions.
Raveling
Raveling occurs when the surface of the asphalt begins to break apart, causing small rocks and gravel to become loose. This can be caused by poor asphalt mix, weather exposure, or heavy traffic. As the surface material deteriorates, the pavement becomes rough and uneven, which can lead to unsafe driving conditions.
If you notice raveling on your roads, it’s important to address it quickly before the damage spreads further.
Depressions and Rutting
Depressions are low areas in the pavement surface caused by improper compaction during installation. These can hold water, leading to further pavement deterioration. Rutting, on the other hand, is the formation of grooves or channels in the wheel paths of the road due to heavy traffic. Both distresses can lead to water pooling and further damage if not addressed in time.
