FLEXIBLE PAVEMENT DESIGN IN IDAHO

REVIEWED ARE FLEXIBLE PAVEMENTS DESIGN METHODS USED BY THE IDAHO DEPARTMENT OF HIGHWAYS SINCE SOILS TESTS WERE BEGUN IN 1938. CALIFORNIA BEARING RATIO TESTS WERE USED PRIOR TO WORLD WAR II, BUT IN 1942 AN EMPIRICAL SOIL FORMULA SIMILAR TO GROUP INDEX WAS ADOPTED AND USED UNTIL 1950 FOR EVALUATING SUBGRADE SOILS FOR FLEXIBLE PAVEMENT DESIGN. THE HVEEM STABILOMETER HAS BEEN USED FOR BITUMINOUS WORK SINCE 1938, BUT CONSTRUCTION OF A KNEADING COMPACTOR IN 1950 MATERIALLY EXPEDITED THE WORK. THE PAPER BY HVEEM AND CARMANY ON FACTORS UNDERLYING THE RATIONAL DESIGN OF PAVEMENTS IN 1948 LED TO ADOPTION OF RESISTANCE VALUE CRITERIA FOR THE DESIGN OF FLEXIBLE PAVEMENTS. THE PAPER REVIEWS OTHER CRITERIA CONSIDERED BY IDAHO IN THE DESIGN OF FLEXIBLE PAVEMENTS. IT CONCLUDES THAT AFTER SEVEN YEARS USE OF RESISTANCE VALUE CRITERIA, THIS METHOD IS SATISFACTORY AND PROPER UTILIZATION OF THESE DATA WILL DO MUCH TOWARD REDUCING THE NUMBER OF SUBGRADE, BASE, AND SURFACING FAILURES ON IDAHO ROADS. /AUTHOR/
