ELASTIC PROPERTIES OF PAVEMENT COMPONENTS BY SURFACE WAVE METHOD

THE PRESENT STUDY EXPLORES THE FEASIBILITY OF USING VIBRATION METHODS IN DETERMINING THE RAYLEIGH WAVE VELOCITY AND THEREBY THE ELASTIC PROPERTIES OF A THREE- LAYER PAVEMENT IN WHICH THE SURFACE LAYER HAS A MODULUS OF ELASTICITY LESS THAN THAT OF THE INTERMEDIATE LAYER; A TYPICAL EXAMPLE IS AN ASPHALT-CEMENT LAYER OVERLYING THE SOIL-CEMENT BASE. WHEN THE INTERMEDIATE LAYER IN A THREE-LAYER COMPOSITE PAVEMENT IS STIFFER THAN THE SURFACE LAYER, THE EXISTING PROCEDURE TO DETERMINE THE RAYLEIGH WAVE VELOCITY OF THE FORMER CANNOT BE APPLIED. A CORRECTION PROCEDURE IS PROPOSED; THE RAYLEIGH WAVE VELOCITY AND THE THICKNESS, DETERMINED ACCORDINGLY, ARE BOTH WITHIN 9 PERCENT OF THE ACTUAL VALUES. /AUTHOR/
