Evaluation of the Model 2000 Road Rater

摘要

This study was conducted to evaluate the Model 2000 Road Rater as a non-destructive testing device on flexible pavements, rigid pavements, composite pavements and subgrade soils. Emphasis was on the temperature and seasonal response, deflection basin shape, and measurement of resilient modulus of flexible pavements; by the Road Rater. The findings resulted in the Road Rater being utilized as a practical NDT device for the Minnesota DOT.
