EVALUATION OF FULL DEPTH ASPHALTIC CONCRETE PAVEMENTS

The report provides a review of the performance and structural characteristics exhibited on two full depth asphaltic concrete pavement projects constructed on the Louisiana interstate system. The roughness characteristics of both full depth projects were evaluated by means of the Mays Ride Meter. Roughness values ranged from 40 to 80 inches per mile indicating a 'very good' to 'good' riding surface. The structural characteristics of these projects were determined by means of the Dynamic Deflection Determination System in conjunction with visual inspection. Deflection values have increased gradually during the two years following construction but remain within the acceptable range for 13 inches of asphaltic concrete. The surface curvature index values indicate good load transfer capability. Other than slight pitting of the wearing course in the wheelpaths, no rutting or other visual signs of deterioration were observed.
