PAVEMENT BLOWUPS CORRELATED WITH SOURCE OF COARSE AGGREGATE

RESULTS ARE GIVEN OF A STUDY OF THE PERFORMANCE OF 3300 MILES OF RIGID PAVEMENT CONSTRUCTED IN INDIANA FROM 1921- 1943. THE DATA WERE OBTAINED FROM FIELD PERFORMANCE SURVEYS MADE OVER A PERIOD OF TWO YEARS, TOGETHER WITH RECORDS OF CONSTRUCTION AND MATERIALS OBTAINED FROM THE CONSTRUCTION AND TESTING DEPARTMENTS OF THE STATE HIGHWAY COMMISSION OF INDIANA, AND FROM BLOWUP REPORTS OBTAINED FROM THE MAINTENANCE DEPARTMENT. IN ANALYZING THE DATA, IT WAS FOUND THAT THERE WERE 2404 BLOWUPS IN THE 2623 MILES WITHOUT EXPANSION JOINTS AND THAT 851 MILES CONTAINED NO BLOWUPS, WHILE 1715 MILES (65%) CONSTRUCTED FROM 82 COARSE AGGREGATE SOURCES CONTAINED ONLY 203 BLOWUPS. IN CONTRAST, 1188 BLOWUPS WERE FOUND IN 284 MILES OF PAVEMENTS CONSTRUCTED WITH MATERIAL FROM ONLY FIVE DIFFERENT SOURCES. FURTHERMORE, 97.1 MILES OF PAVEMENT CONSTRUCTED WITH MATERIAL FROM ONE OF THESE SOURCES CONTAINED 707 BLOWUPS (29.6% OF THE TOTAL BLOWUPS IN THE STATE). THESE DATA WERE CONSIDERED IMPORTANT, SINCE IT WAS OBSERVED GENERALLY THAT MAP CRACKING, SERIOUS DISINTEGRATION, AND A RELATIVELY SHORT PAVEMENT LIFE ACCOMPANIED THE BLOWUP FAILURES. IT WAS CONCLUDED, ON THE BASIS OF A STATISTICAL ANALYSIS OF THESE BLOWUP DATA THAT: /1/ AN OUTSTANDING CORRELATION EXISTED BETWEEN CERTAIN COARSE AGGREGATES USED IN THE CONCRETE MIX AND THE BLOWUP PERFORMANCE OF THE PAVEMENTS, /2/ NO CORRELATION EXISTED BETWEEN THE CEMENT, FINE AGGREGATE, TRAFFIC, OR SUBGRADE SOILS USED AND BLOWUP PERFORMANCE, AND /3/ EXTENSIVE LABORATORY RESEARCH IS INDICATED AS NECESSARY TO DETERMINE THE BASIC REASON FOR THE VARIATION IN PERFORMANCE BETWEEN AGGREGATE SOURCES AND TO DEVELOP NEW AND BETTER METHODS OF TESTS BY WHICH THOSE AGGREGATES WHICH PRODUCE CONCRETE OF AN UNSATISFACTORY QUALITY CAN BE IDENTIFIED BEFORE THEY ARE INCORPORATED IN THE CONCRETE PAVEMENT. /AUTHOR/
