Two types of condition surveys for pavement structural evaluation, decision surveys and design surveys, are defined. The decision survey is examined further by using the results of a recent survey conducted among state and other selected highway agencies. Emphasis is placed on the amount and types of distress mechanisms that influence maintenance decisions. The criteria that nondestructive equipment should meet to assist in conducting such surveys are stated, and the effectiveness of the two methods used to collect pavement condition information is compared. A related statistical sampling study that uses Dynaflect is shown, and promising developmental techniques for measuring stiffness and cracking of pavements are presented. /Author/
