PORTLAND CEMENT CONCRETE PAVEMENT DESIGN

THE PROCEDURE IS DESCRIBED FOR THE DESIGN OF PORTLAND CEMENT CONCRETE PAVEMENTS. THE DESIGN PROCEDURE ENABLES THE ENGINEER TO MATCH A PAVEMENT SECTION TO HIS DESIGN LOADS - A THICK SECTION FOR HEAVY LOADING AND A MORE ECONOMICAL SECTION FOR LIGHT LOADINGS. THE PROCEDURE PROVIDES A CONSERVATIVE APPROACH TO DESIGN IN SEVERAL DIFFERENT WAYS' /1/ THE R-VALUE TO K-VALUE RELATIONSHIP CURVE HAS BEEN DRAWN BELOW THE MINIMUM OF ALL TEST DATA, /2/ ALL K-VALUES HAVE BEEN CORRECTED DOWN TO SATURATED CONDITIONS, EVEN THOUGH MANY EMBANKMENTS MAY NEVER BECOME SATURATED, /3/ DESIGN CONCRETE STRENGTH /MR/ IS FOR 28 DAYS. CONCRETE WILL GAIN STRENGTH FOR SEVERAL YEARS, /4/ LOAD SAFETY FACTOR UP TO 130 PERCENT FOR VERY HEAVY LOADS, /5/ THE FATIGUE CURVE HAS BEEN DRAWN ON THE CONSERVATIVE SIDE OF ALL TEST DATA. LOADS CAUSING STRESS RATIOS OF 0.50 ARE COUNTED EVEN THOUGH TEST DATA INDICATE STRESS RATIOS LESS THAN ABOUT 0.55 VERY LIKELY CONTRIBUTE LITTLE FATIGUE, AND /6/ SMALL-SCALE STATIC LOAD MODEL TESTS HAVE INDICATED THAT THE THEORY YIELDS HIGHER STRESSES THAN ACTUALLY EXPERIENCED IN THE SLAB /3/.
