TEMPERATURES OF BITUMINOUS MIXTURES AND TIRES DURING COMPACTION /IN FRENCH/

DURING TESTS CARRIED OUT TO INVESTIGATE THE STICKING OF COMPACTION TIRES TO BITUMINOUS MIXTURES, OBSERVATIONS WERE MADE CONCERNING THE CHANGES IN TEMPERATURES DURING APPLICATION. DETAILS ARE GIVEN OF THE MIXING PLANT, WEATHER CONDITIONS, TEMPERATURE MEASUREMENTS AT THE TIME OF APPLICATION (TEMPERATURE OF THE BITUMINOUS MIXTURE), AND TEMPERATURE OF THE TIRES AT THE TIME OF COMPACTION. IN THE CASE OF THE BITUMINOUS MIXTURE, A CONTINUOUS DECREASE WAS OBSERVED; IN THE CASE OF THE TIRES, A FIRST PHASE OCCURS DURING WHICH THE TEMPERATURE BECOMES EVEN (FROM 60 DEGREES THERE IS NOT MORE STICKING). THE MAXIMUM TEMPERATURE REACHED IS 75 DEGREES AFTER 15 MINUTES. DURING THE SECOND PHASE, THE TEMPERATURE OF THE TIRES FOLLOWS THE DECREASE IN TEMPERATURE OF THE BITUMINOUS MIXTURE, WITH A TEMPERATURE LAG OF 15 DEGREES C. /LCPC (A)/RRL/
