Zeus by Road Science

ZEUS INTERPRETS WEATHER DATA, SO THAT YOU DON'T HAVE TO Zeus gives the user clear advice on when and where they are able to spray bitumen emulsion to prevent the risk of wash-off from a rain event. Emulsion is safer, produces less emissions and is now technically superior to hot cut back bitumen for chip seals. Recent advances in technology mean that emulsions are now capable of being used in all chip seal types in New Zealand. The major advantages of emulsion are: - Safety, hazards are eliminated, explosions, fires and serious burns. - Environmental, emissions are significantly reduced (almost 50% less). - Application rates may be able to be reduced. - Improved adhesion means reduced chip loss and therefore reduced rework Emulsification is the process of combining two liquids that cannot be mixed. It is, in essence, the same process by which many foods, including tomato sauce, remain suspended and pourable without the elements separating or settling. WE HAVE A DESIRE TO ELIMINATE WASH-OFF Emulsion is a water based system and should not be sprayed in the rain. While emulsion seals applied in rain usually do not lose chip they can create an unsightly wash off which should be avoided. Road Science has improved the cure time of emulsion to lessen the risk of wash off and have a product performance forecast tool to assist teams assess the risk of wash off. It should be noted that while hot cut backs have been sprayed in rain, chip will not adhere in wet conditions and stripping is a significant risk.
