Effect of speed hump characteristics on pavement

 · Pavement condition is characterized by many indices. One of them is the pavement condition index (PCI) which will be used in this paper. The PCI was developed by Shahin and Kohn (1981) is a numerical rating indicator based on a scale of 0–100 ().At 100 the pavement condition is assumed to be in perfect condition and 0 represents a completely failed pavement section.

Existing Surface Preparation for OverlaysPavement

Overlays (either structural or non-structural) make up a large portion of the roadway paving done today.The degree of surface preparation for an overlay is dependent on the condition and type of the existing pavement. Generally the existing pavement should be structurally sound level clean and capable of bonding to the overlay.
