EXPANSIVE LIMESTONE AGGREGATE IN A CONCRETE PAVEMENT

THIS IS THE ANALYSIS OF THE CAUSATIVE FACTORS OF THE PREMATURE AND RECURRENT BLOWUPS AND SURFACE CRACKING OF I 65-1(13)13. PAVEMENT BLOWUPS AND EXTENSIVE CRACKING OCCURRED WITHIN TWO YEARS AFTER COMPLETION. THE CRACK PATTERN RESEMBLED THE CONFIGURATION OF THE WIRE MESH - WHICH WAS VIBRATED INTO POSITION AFTER THE CONCRETE WAS SPREAD AND SCREENED. THE BLOWUPS WERE ATTRIBUTED TO EXPANSIVE FORCES ARISING FROM A LIMESTONE AGGREGATE WHICH HAS BEEN IDENTIFIED WITH SPECIFIC LEDGES IN THE SOURCE QUARRY. THE NATURE OF THE AGGREGATE WAS SUCH THAT ITS DELETERIOUS OR EXPANSIVE CHARACTER WOULD NOT HAVE BEEN DETECTED BY THE SPECIFICATION TESTS AND ROUTINE SAFEGUARDS THEN IN EFFECT. THIS REPORT INCLUDES A RELEVANT HISTORY OF THE PROJECT AND RESULTS FROM THE SEVERAL INVESTIGATIVE TESTS UNDERTAKEN.
