• DO store at the temperature specified for the particular grade and application • DO NOT permit the asphalt emulsion to be heated above 185ºF Elevated temperatures evaporate water, changing the characteristics of the asphalt emulsion • DO NOT let the emulsion freeze This breaks the emulsion, separating the asphalt from the water.Prime and Tack Coat 04 27 06applicability and benefits of prime and tack coat, prime and tack coat effectiveness, materials used and when and where they are used CFLHD’s current construction specifications were compared with best practices determined from the literature and phone surveys of.Notes for resealing TNZ P/4emulsion application rate is about 10 litres per square metre compared with an equivalent asphaltic binder residual rate of 055 litres per square metre plus small diluent allowance Bitumen distributors are only calibrated for total hot spray rates of 08 litres per square metre or more and would require greater travel speed than the calibrated.
31 Asphalts change in volume with change in temperature They are loaded or transferred at widely varying temperatur Volume correction factors are used to adjust bulk volumes measured at those temperatures to corresponding volumes at a base temperature of 15°C or [60°F] for the purposes of custody transfer and accounting operations.
