Bitumen and bituminous binders. Determination of storage stability of modified bitumen Ingestion-build-135476 BS EN 449:19971 Scope This European Standard specifies a method for measuring the storage stability of modified bitumen at high temperatures. NOTE Modified bitumen and, in particular, polymer modified bitumen, which consist of mainly bitumen and at least one additional agent, are known to display phase separation under certain conditions. WARNING The use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does
