Anionic Bitumen Emulsions for Waterproofing
نویسندگان
چکیده
Bitumen emulsions (BE) are widely used in road construction, for building and structure waterproofing. Storage stability is one of the main BE requirements. They should only break on contact with surface. The sodium oleate effect as a surfactant anionic bitumen waterproofing purposes has been studied. increased storage have developed. optimal content oleate, providing high complex emulsion resulting binder properties determined.

Retrospective exposure assessment for carcinogenic agents in bitumen waterproofing industry in Finland and denmark.
OBJECTIVES The purpose of the study was (i) to identify the carcinogenic agents that may cause confounding when studying the exposure-response relationship between bitumen fume exposure and cancer among roofing membrane-manufacturing workers and roofers and (ii) to assess exposures to the identified carcinogens and bitumen fume in roofing membrane manufacturing and roofing in Finland and Denmar...
متن کاملTitle : Thermal Destabilisation of Bitumen - in - Water Emulsions - A Spinning Drop Tensiometry
Nonionic surfactant-stabilised oil-in-water emulsions offer a potentially useful vehicle for transporting heavy crude oils from oilfields to refineries or distribution terminals. Prior to refining, separation of the oil from the emulsion is necessary. Previous studies have suggested that heating the emulsion is sufficient for destabilisation and recovery of the oil. The present work examines th...
متن کاملStudies of the microstructure of polymer-modified bitumen emulsions using confocal laser scanning microscopy.
Polymer-modified bitumen emulsions present a safer and more environmentally friendly binder for enhancing the properties of roads. Cationic bitumen emulsion binders containing polymer latex were investigated using confocal laser scanning microscopy. The latex was incorporated into the bitumen emulsion by using four different addition methods and all emulsions were processed with a conventional ...
متن کاملInvestigating the effects of salts on the coalescence process in bitumen emulsions
The breaking and coalescence process in bitumen emulsions during their application strongly influences the resulting long-term mechanical performance of the cold mix asphalt. This phase separation process is affected by physico-chemical changes at the bitumen/water interface. This paper describes the effects of addition of different salts on the destabilization of bitumen emulsions. This study ...
متن کاملThe Human Bitumen Study
Recently, the Human Bitumen Study has been finished (Schlüter, 2011). Including 500 workers from more than 80 construction sites it represents the world-wide largest study on adverse health effects caused by bitumen. The study answers a question that has been controversially discussed since decades: Bitumen exposed workers do not show higher levels of DNA damage than unexposed individuals. On t...
