Stable road paving is crucial to driver safety. Over time, long cracks can form down the centerline of a street and reduce the pavement's visual appeal and structural integrity. Luckily, contractors can repair and prevent this issue. Use the helpful guide below to create adequate conditions for motorists.

How Longitudinal Cracking Develops

Longitudinal cracking is most common in asphalt joints, where adjacent lanes meet. Joints are the weakest points on the road and not intended to be driven on. Unfortunately, drivers do go over these areas, leading to asphalt fatigue. Cracks may first form below the surface and grow, or start from the top and reach the foundation.

Cold temperatures also cause damage. Asphalt compacts when the ambient air drops below 50 degrees, straining road paving materials. Coupled with the weight of cars, the resulting stress can crack the asphalt.

Over time, water seeps into small cracks and erodes the material further, forming alligator cracking. When left unaddressed, crumbling sections can collapse into potholes and pose safety issues for drivers.

How to Address Longitudinal Cracking on Roads

Thin longitudinal cracking, categorized as low-severity, can be repaired with asphalt fillers. A paving contractor fills the gap with a caulk gun and seals it to create a moisture-tight barrier. High-severity cracks greater than half an inch wide require more extensive work. A contractor will remove the cracked section, pour new asphalt, and repave the surface.

Crack prevention begins with installation. During service, professionals should seal joints with anti-moisture additives and widen lanes to ensure joints aren’t in the path of vehicles.
