SURFACE DRESSINGS - FOLLOW-UP STUDY

ENDUITS SUPERFICIELS - SUIVI

THE OBJECTIVE OF THE RESEARCH IS TO OBTAIN A BETTER KNOWLEDGE OF THE INFLUENCE OF VARIOUS MIX-DESIGN AND APPLICATION PARAMETERS ON THE QUALITY AND DURABILITY OF SURFACE DRESSINGS. IN 1979 IT IS ENVISAGED: - TO CONTINUE OBSERVATIONS ON EXPERIMENTAL SECTIONS; - TO BUILD NEW SECTIONS WITH DIFFERENT MIX-DESIGN FORMULAE AND IN PARTICULAR WITH TRANSVERSELY DIFFERENTIAL STRUCTURES; - TO CONTINUE STUDYING THE IN-SITU BEHAVIOUR OF BINDERS; - TO COMPLETE THE STUDY OF THE EMBEDMENT OF AGGREGATES IN THE BINDER; - TO CONDUCT AN EXPERIMENTAL STUDY OF THE LAYING OF SURFACE DRESSINGS ON NON-STABILIZED GRAVEL AND IN GROOVED CONCRETE; - TO CONTINUE OBSERVING SITES BUILT WITH HEATING MACHINES AND TO CARRY OUT LOCALIZED REPAIR; - TO OBSERVE LOCALIZED REPAIR ON HIGH-PERFORMANCE SURFACE DRESSINGS; - TO DRAFT A FILE ON BINDERS (MIXED AND MODIFIED BINDERS); - TO INVESTIGATE THE POSSIBILITIES OFFERED BY THE SOLAIZE CIRCULAR TEST TRACK FOR THE STUDY OF SURFACE DRESSINGS.
