Abstract

"CONCENTRADO ESTáVEL DE BETUME EMBORRACHADO, COMPOSIçãO BETUMINOSA E MéTODO DE FORMAçãO DO REFERIDO CONCENTRADO". Os concentrados de betume emborrachado estáveis são preparados formando-se inicialmente uma massa compreendendo betume e partículas de borracha fragmentada em uma quantidade de pelo menos cerca de 15% em peso da massa com a borracha fragmentada sendo inchada in situ, e aplicando condições de temperatura e cisalhamento à massa para dissociar a rede vulcanizada das partículas de borracha e para incorporar o vulcanizado digerido no betume. O concentrado de betume emborrachado é estável contra sedimentação de partículas de borracha seguindo o armazenamento do concentrado a cerca de 160<198>C por 48 horas e a diluição a uma concentração inferior no ensaio de solubilidade ASTM."STABLE CONCENTRATE OF BUILT-UP BETUME, BETUMINOUS COMPOSITION AND METHOD OF FORMING THE CONCENTRATE". Stable rubberized bitumen concentrates are prepared by initially forming a mass comprising bitumen and fragmented rubber particles in an amount of at least about 15% by weight of the mass with the fragmented rubber being swollen in situ, and applying temperature and temperature conditions. mass shear to dissociate the vulcanized network from the rubber particles and to incorporate the digested vulcanized into the bitumen. Rubberized bitumen concentrate is stable against sedimentation of rubber particles following storage of the concentrate at about 160Â ° C for 48 hours and dilution to a lower concentration in the ASTM solubility test.
