THIN OVERLAY BITUMINOUS MACADAM FOR THE CONTROL OF REFLEX CRACKING
REFLEX CRACKING IN PAVEMENT OVERLAYS IS AN EXTENSIVE PROBLEM BROUGHT ABOUT BY ATTEMPTS TO CORRECT OLD PAVEMENT IN NEED OF REHABILITATION. BECAUSE OF THE DISSATISFACTION WITH PREVIOUS METHODS, IN 1959 THE DECISION WAS MADE TO USE A 3-IN. COURSE OF BITUMINOUS MACADAM PAVEMENT TO REHABILITATE AN EXTREME CASE OF OLD, BADLY CRACKED BITUMINOUS CONCRETE RUNWAY PAVEMENT. BASED ON KNOWLEDGE GAINED FROM EXPERIENCE, IN ORDER TO DEVELOP A SATISFACTORY MACADAM PAVEMENT THE AUTHOR CONCLUDES THAT THE FOLLOWING CONDITIONS SHOULD BE MET' /1/ PROVIDE FOR APPROPRIATE EQUIPMENT, /2/ PROVIDE FOR COMPETENT SUPERVISION, /3/ MAKE SURE THAT STONE IS SUFFICIENTLY HARD, IS NOT SUSCEPTIBLE TO EXCESSIVE STRIPPING BY BITUMINOUS BINDERS, DOES NOT CONSIST OF AN EXCESSIVE AMOUNT OF ELONGATED PARTICLES, IS SATISFACTORILY CLEAN, AND DOES NOT CONTAIN AN EXCESSIVE AMOUNT OF MOISTURE, /4/ CALL FOR A BITUMINOUS BINDER THAT WILL ADEQUATELY FULFILL ITS INTENDED FUNCTION, AND /5/ ACTUALLY CONSTRUCT THE PAVEMENT ONLY IN SATISFACTORY WEATHER
