KN-2872 Rolling Thin Film Oven
this oven indicates approximate change in properties of asphalt during conventional hot-mixing ar about 150℃ as indicated by viscosity and other rheological measurements.it yields a residue which approximates the asphalt condition as incorporated in the pavement.if the mixing temperature differs appreciably from the 150℃ level. more or less effect on properties will occur. this oven also can be used to determine mass change,which is a measure of asphalt volatilityRead

KN-4402 Rotational Viscometer for Asphalt Viscosity
KN-4402 Rotational Viscometer for Asphalt Viscosity conforms to ASTM D4402 Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer. A rotational viscometer is used to measure the apparent viscosity of asphalt at elevated temperature. The torque on the apparatus-measuring geometry, rotating in a thermostatically controlled sample holder containing a sample of asphalt, is used to measure the relative resistance to rotation. The torque andRead

KN-36 Softening Point of Asphalt (Ring-and-Ball)
The softening point is useful in the classification of bitumens, as one element in establishing the uniformity of shipments or sources of supply, and is indicative of the tendency of the material to flow at elevated temperatures encountered in serviceRead
