Eliminating Roughness: How Averaging Leveling Beams Maximize Pavement Service Life

2025-10-18

Pavement roughness, even in subtle forms, is a major contributor to dynamic loading, which accelerates wear, increases repair costs, and shortens the service life of a road. By deploying our Averaging Leveling Beam technology, contractors can proactively eliminate these initial surface irregularities, thereby maximizing the lifespan of their concrete pavement and reducing the Total Cost of Ownership for the asset owner.

The fundamental principle is that pavements built smoother, stay smoother longer. The Leveling Beam's ability to reference the grade over a base length of 10 meters or more ensures that any short, high-frequency roughness that would typically plague a newly poured road is effectively ironed out before the concrete has a chance to set. This results in an exceptionally low starting IRI value. When a pavement is smoother, vehicle suspensions absorb less impact, leading to a significant reduction in the destructive dynamic forces transferred to the concrete slab. Over time, this mitigation of stress slows the formation of fatigue cracks and joint deterioration, directly extending the period before major rehabilitation is required. For transportation agencies that utilize performance-based specifications and incentivize low IRI scores, our Averaging Leveling Beam is a critical investment that guarantees project bonuses and delivers a high-quality, long-lasting product that benefits both the road builder and the traveling public.
