1.4. Deduct Values. Deduct value curves have been included in this handbook for each
distress. The curves for corrected deduct values are also included as Figure 1.2.
1.5. Frequently Occurring Problems. Frequently occurring problems that are commonly
encountered are outlined in Table 1.1. for emphasis, and the rater should be aware of these
problems before starting the condition survey.
1.6. Inspection Procedure. Each sample unit chosen should be individually inspected. The
actual inspection is performed by walking over the sample unit to measure the distress type and
severity and recording the data on the flexible pavement survey data sheet (Figure 1.3.). This
figure should be enlarged and copied for actual use. One data sheet is used for each sample unit.
Each column on the data sheet is used to represent a distress type, and the amount and severity
of each distress located are listed in the column. Sample units are selected in accordance with
guidance contained in TM 5-826-6/AFR 93-5.
