ASPHALT PAVEMENT TEMPERATURES

THE USE OF THICKER ASPHALT PAVING COURSES IN HEAVY-DUTY HIGHWAYS HAS RESULTED IN THE NEED FOR MORE INFORMATION ON TEMPERATURE VARIATIONS IN PAVEMENT STRUCTURES. TEMPERATURE DATA ARE NECESSARY IN STUDIES OF PAVEMENT DEFLECTIONS, STRESSES AND STRAINS UNDER MOVING WHEEL LOADS. PAVEMENT TEMPERATURE DATA ARE OF INTEREST IN ANY STUDY OR TEST INVOLVING THE TEMPERATURE-DEPENDENT MECHANICAL PROPERTIES OF PAVING MIXTURES OR PAVING ASPHALTS. THE PAVEMENT TEMPERATURE STUDIES REPORTED WERE CONDUCTED TO PROVIDE INFORMATION ON TEMPERATURE VARIATIONS IN THICKER ASPHALT-CONCRETE PAVEMENTS THAT WOULD BE APPLICABLE IN MANY AREAS OF THE UNITED STATES. PAVEMENT TEMPERATURES WERE MEASURED AT THE SURFACE AND AT DEPTHS OF 2, 4, AND 6 IN. IN A 6-IN. THICK ASPHALT-CONCRETE PAVEMENT, AND AT DEPTHS OF 2, 4, 6, 8, 10 AND 12 IN. IN A 12-IN. THICK ASPHALT-CONCRETE PAVEMENT. A TEMPERATURE RECORDER WAS USED TO RECORD AIR AND PAVEMENT TEMPERATURES AT THE TEST SITE IN COLLEGE PARK, MARYLAND, FROM JUNE 1, 1964, TO MAY 31, 1965. THE DURATIONS OF VARIOUS TEMPERATURE LEVELS, AND MAXIMUM, MINIMUM AND AVERAGE TEMPERATURES BASED ON HOURLY TEMPERATURES AT THE VARIOUS DEPTHS, ARE REPORTED FOR EACH MONTH AND FOR THE ENTIRE YEAR. TEST DATA AND INFORMATION ON DAILY PAVEMENT TEMPERATURE CHANGES WITH DEPTH, AND RATES OF TEMPERATURE CHANGE, ARE ALSO REPORTED. /AUTHOR/
