How is Pavement Condition Index determined?

How is Pavement Condition Index determined?

The method is based on a visual survey of the number and types of distresses in a pavement. First, the type and extent of existing distresses, their severity level is collected. Next, distress density is calculated for each type of distress.

What is pavement quality index?

To determine the order and priorities of which streets will receive a pavement treatment, a Pavement Quality Index (PQI) score is developed for each street segment, which is measured 0-100 (Poor to Excellent).

What is PCI value?

The Pavement Condition Index (PCI) is a numerical indicator that rates the general surface condition of a pavement or road. It is a statistical measure which requires manual/visual inspection and survey of the required roads, and was developed by the United States Army Corps of Engineers.

How is PCI value calculated?

The PCI is computed using the relation PCI = 100 − CDV.

What is Pavement Condition Index (PCI)?

The Pavement Condition Index (PCI) is a numerical index between 0 and 100 which is used to indicate the general condition of a pavement. It is widely used in transportation civil engineering. It is a statistical measure and requires manual survey of the pavement.

What is a pavement condition rating?

This score, sometimes called a pavement condition rating, quantifies a pavement’s overall performance and can be used to help manage pavement networks. By carefully choosing the rating scale (called the condition index), pavement condition scores can be used to (Deighton, 1997 [1] ): Trigger treatment .

What is an ASTM pavement index?

It is a statistical measure and requires manual survey of the pavement. This index was originally developed by the United States Army Corps of Engineers as an airfield pavement rating system, but later modified for roadway pavements and standardized by the ASTM.

What are the factors that affect the condition of the pavement?

The condition of the pavement is based on the following factors: • Type of Distress• Amount of Distress• Severity of Distress• Deduct Values (function of first three) The Pavement Condition Index (PCI) is a measurement scale is based upon a condition index ranging from zero for a failed pavement to 100 for pavement with perfect condition.
