TEST PROCEDURE. DETERMINATION OF THE LANGE REFLECTOMETER VALUE OF CRUSHED STONE

MODE OPERATOIRE. DETERMINATION DE LA VALEUR REFLECTOMETRIQUE LANGE DE PIERRES BROYEES

FOR THE SPREADING OF PRECOATED CHIPPINGS ON ASPHALTIC CONCRETE SURFACINGS (TYPE 2 OR TOPEKA ASPHALTIC CONCRETE), SPECIFICATIONS ENVISAGE THE POSSIBILITY OF USING LIGHT COLOURED AGGREGATES EITHER ON THEIR OWN OR IN MIXTURES. A TEST METHOD WAS DEVELOPED TO ENABLE THE PRACTISING ENGINEERING AND SITE MANAGER TO EVALUATE THE WHITENESS OF MATERIALS FOR THE SPREADING OF BITUMINOUS SURFACINGS WITH PRECOATED CHIPPINGS. SUCH A METHOD IS ALSO USEFUL FOR THE SPREADING OF PRECOATED CHIPPINGS ON CONCRETE SURFACINGS OR RESIN OR BITUMINOUS DRESSINGS; OR FOR AGGREGATES USED IN ORDINARY SURFACINGS. THE METHOD SELECTED CONSISTS IN DETERMINING THE LANGE REFLECTOMETER VALUE; IT USES AGGREGATES GROUND INTO POWDER (0,420 MM TO 1 MM). THE PRINCIPLE OF THE METHOD, THE MEASURING APPARATUS AND ITS CALIBRATION, SAMPLING, MEASUREMENTS AND PRESENTATION OF RESULTS ARE DESCRIBED AND ILLUSTRATED WITH EXAMPLES.
