Divided into 4 sessions and one panel workshop/discussion onissues related to standardization of backcalculation procedures.The papers presented focus on the area of backcalculation of layermoduli techniques and comparisons of material moduli as measured inthe laboratory to values calculated from field deflectionmeasurements. Information from these papers and discussions wereused to establish whether a backcalculation procedure could bestandardized based upon the current state-of-the-art technology.Provides readers with much of the latest information in the areasof pavement evaluation using NDT techniques, and application ofthat data for use in pavement design.

In 5 sections:

• Measurement and calculation Techniques in the Field andLaboratory

• Problems/errors Associated with Backcalculation Methods andDesign Parameters

• NDT for Other Pavement Uses

• Proposed Standard Guide.
