Distress Pavement Identification
Raymond Ehrhard, P.E.
Overview
The Strategic Highway Research Program (SHRP)
developed a Long-Term Pavement Performance (LTPP) program to provide a
consistent, uniform basis for collecting distress data for pavement
performance. This course provides guidance to improve communications within the
pavement community by fostering more uniform and consistent definitions of
pavement distress. Highway agencies, airports, parking facilities,
transportation engineers, and others with significant investment in pavements
will benefit from adopting a standard distress language. It also serves as a
valuable training tool for highway agencies.
The course follows the manual, focusing on three
particular types of pavements: (1) asphalt concrete-surface, (2) jointed
portland cement concrete, and (3) continuously reinforced portland cement
concrete. Various distress conditions are described and illustrated using
diagrams and pictures. Methods of detection and measurements are defined.
Detailed guidance is provided to the student on how to conduct a distress survey
and how to identify severity levels for various distressed pavement conditions.
The exam for this course contains multiple choice
questions and includes pictures and illustrations to test the student on the
materials learned.
The student is expected to read and review the material contained in; Distress
Identification Manual for the Long-Term Pavement Performance Program (Fourth
Revised Edition), Publication NO. FHWA-RD-03-031, June 2003.
The student must take a multiple-choice quiz consisting of forty (40) questions
at the end of the course to obtain 8 PDH credits.
