If the base is not compacted properly, once traffic is released, the constant shifting underground causes the asphalt to crack and shift. Once these cracks hit the base and water intrusion is allowed, the deterioration will accelerate and the asphalt will begin to crumble.
what causes asphalt to deteriorate?
Factors that cause deterioration in pavement include. This causes raveling and shrinking cracks which allow water to penetrate beneath the surface. Chemical / petroleum exposure – the introduction of chemicals to asphalt, including gas and oil, can soften the asphalt and cause it to break down more rapidly.
