The instrument is designed and made as per T0755 “Emulsified Asphalt Slurry Seal Mixture Rolling Test” in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine asphalt quantity in the emulsified asphalt slurry seal mixture to ascertain whether there is too much asphalt, so that to set upper limit for asphalt used. The instrument is used to decide the preferred asphalt quantity in the emulsified asphalt slurry seal mixture together with wet wheel abrasion tester.
