TRACKING TEST ON HOT-COATED MATERIALS - CHARACTERIZATION OF THE BEHAVIOUR OF BITUMINOUS MIXTURES DURING APPLICATION

ESSAI D'ORNIERAGE A CHAUD - CARACTERISATION DU COMPORTEMENT A LA MISE EN OEUVRE DES MATERIAUX HYDROCARBONES

THE TRACKING TEST ON HOT-COATED MATERIALS IS EASY TO PERFORM. IT REQUIRES: 2 SAMPLES TO DETERMINE THE COMPACTION METHOD TO BE USED FOR OBTAINING 80% STATE OF COMPACTION, AND 2 SAMPLES ON WHICH THIS STATE OF COMPACTION IS TESTED. THE TEST DEVICE USED IS THE TRACKING MACHINE OF THE CECP AT ANGERS, TO WHICH AN EFFICIENT SIMPLE LEVEL SENSOR IS AFFIXED. THIS TEST IS HIGHLY SELECTIVE AND EXTREMELY USEFUL IN MIX-DESIGN STUDIES. IT IS RELATED TO THE REAL BEHAVIOUR OF GRAVEL-BITUMEN DURING APPLICATION AND FAITHFULLY REPRODUCES THE TENDENCY OF GRAVEL-BITUMEN TO CREEP UNDER COMPACTION. IT COULD ALSO PROVE USEFUL IN INVESTIGATIONS INTO THE INFLUENCE OF THE CRUSHING AND MICROROUGHNESS INDEX ON THE BEHAVIOUR OF GRAVEL STABILIZED AT THE APPLICATION STAGE (SPREADING, LAYING).
