STUDY OF THE APPLICATION OF CHROMATOGRAPHY ON PERMEABLE GEL (GPC) TO THE CHARACTERIZATION OF ORGANIC BINDERS

ETUDE DE L'APPLICATION DE LA CHROMATOGRAPHIE SUR GEL PERMEABLE (GPC) A LA CARACTERISATION DES LIANTS ORGANIQUES

THE AIM OF THIS RESEARCH IS TO STANDARDIZE THE DEVELOPMENT OF CHROMATOGRAPHY ON PERMEABLE GEL (GPC) IN THE CHARACTERIZATION OF THE ORGANIC BINDERS USED IN CIVIL ENGINEERING. IN 1979 IT IS ENVISAGED TO STUDY: THE APPLICATION OF UNIVERSAL CALIBRATION IN RAPID GPC IN THE CASE OF ISOLATED BITUMEN FRACTIONS BY MEANS OF PREPARATORY GPC; THE USE OF RAPID GPC FOR CHARACTERIZING THE NATURAL AND ARTIFICIAL AGEING OF ROAD BITUMEN; THE APPLICATION OF GPC TO THE QUALITATIVE AND QUANTITATIVE CHARACTERIZATION OF BITUMEN-POLYMER MIXTURES USED FOR BITUMINOUS MIXTURES AND SURFACE DRESSINGS; THE APPLICATION OF GPC IN AQUEOUS MEDIUM TO THE CHARACTERIZATION OF LIGNOSULPHONATES AND WATER SOLUBLE PRODUCTS.
