GENERAL DISCUSSION

THE PULSE VELOCITY DATA AND DISCUSSIONS PRESENTED IN THE SYMPOSIUM RELATE PRIMARILY TO CONCRETE. IT IS POINTED OUT THAT ACTUALLY, PULSE VELOCITY TECHNIQUE HAS BEEN USED WITH A CONSIDERABLE SUCCESS FOR THE TESTING OF OTHER MATERIALS SUCH AS SOILS AND BITUMINOUS MIXTURES. THE LABORATORY DATA (PULSE VELOCITY VERSUS COMPRESSIVE STRENGTH, ETC.) HAVE A SCATTERING GENERALLY SIMILAR TO THAT SHOWN BY CONCRETE. IT IS FOUND THAT PULSE VELOCITY DATA FOR SOILS GENERALLY FOLLOW, WITH A FEW EXCEPTIONS, THE PATTERN OBTAINED IN THE LABORATORY TESTING OF CONCRETE UNDER THE SAME CONDITIONS. IT IS CAUTIONED THAT, WHILE EVALUATING PULSE VELOCITY TEST DATA, THE VARIOUS LIMITATIONS SHOULD BE KEPT IN MIND. ALTHOUGH IT IS NOW CONSIDERED ALMOST A GENERAL RULE THAT CHANGES IN QUALITY OF CONCRETE ARE REFLECTED BY CORRESPONDING CHANGES IN PULSE VELOCITY, SEVERAL EXCEPTIONS ARE KNOWN TO EXIST AND TWO ARE REPORTED IN THIS SYMPOSIUM. SUCH EXCEPTIONS OR NEGATIVE CONCLUSIONS POINT TO THE INADEQUACY OF THE EMPIRICAL CONCEPT ALONE IN INTERPRETING THE PULSE VELOCITY TEST DATA AND EMPHASIZE THE NEED FOR A BASIC THEORY.
