PAVEMENT DEFLECTION MEASUREMENT-DYNAMIC: A FEASIBILITY STUDY

THE FEASIBILITY WAS INVESTIGATED OF DEVELOPING A DEVICE OR TECHNIQUE TO PROVIDE RAPID MEASUREMENT OF PARAMETERS INDICATIVE OF ROADWAY CONDITION OR STRUCTURAL CAPACITY. A NEW SYSTEM CALLED "IMPULSE TESTING" HAS BEEN PROPOSED AND CONCEPTS PROVED IN THIS STUDY. THE SYSTEM IS BASED ON THE DEFLECTION OF THE PAVEMENT UNDER IMPULSE LOADING AND ALSO ON THE ENERGY PROPAGATION CHARACTERISTICS OF THE PAVEMENT. THESE TWO PARAMETERS ARE COMBINED TO FORMULATE A QUANTITY WHICH IS CALLED THE IMPULSE INDEX AND WHICH HAS A HIGH DEGREE OF CORRELATION WITH THE STRUCTURAL PROPERTIES OF THE PAVEMENT. /AUTHOR/
