2003 - USA - LTPP Data Collection Manual

This manual was developed to provide a consistent, uniform basis for collecting distress data for the LTPP program.

This manual provides a common language for describing cracks, potholes, rutting,spalling, and other pavement distresses being monitored by the LTPP program.

The manual is divided into three sections, each focusing on a particular type of pavement: (1) asphalt concrete-surfaced, (2) jointed portland cement concrete, and (3) continuously reinforced portland cement concrete. Each distress is clearly labeled, described and illustrated.
