Assessment of catalyst K4 effect in comparison to catalyst K3, including the impacts of additives Polyol and polyphosporic acid
Original language description
Based on the findings summarized in the report no. 1, next assessed group of experimentally designed and produced CRmB binders with application of various chemical additives focuses on analyzing repeatedly the impact of catalyst K4, which has so far shown within the developments of this type of chemical additives quite good effect in the provision of temporary rubber devulcanization. Further, comparison with reference bitumen of 50/70 penetration has been done. This bitumen has been used in the same moment as the base for the preparation of particular variants of CRmB binders. Simultaneously, the requirements stipulated by German regulations for standardised binders of the GmB (CRmB) type can be used where GmB 25/55-50 or 25/55-55 appears to be the most appropriate for further assessment. In all analyzed bitumen variants fine-grained pulverized rubber of 0-0.3 mm grading was used. The rubber content in the bitumen was 15 % by mass. Addition of catalyst K4 (and for comparison also of ca
