ASTM D113 Digital Ductilometer (Tensile Load Series) Ductility Test Machine
KN-113 Digital Ductilometer conforms to ASTM D113 Standard Test Method for Ductility of Bituminous Materials. It is suitable to determine the distance to which it will elongate before breaking when two ends of a briquet specimen of the material are pulled apart at a specified speed and at a specified temperature.

ASTM D4419 Low Temperature Differential Scanning Calorimeter
KN-4419 Low Temperature Differential Scanning Calorimeter conforms to ASTM D4419 Standard Test Method for Measurement of Transition Temperatures of Petroleum Waxes by Differential Scanning Calorimetry (DSC). DSC in a convenient and rapid method for determining the temperature limits within which a wax undergoes during transitions. The highest temperature transition is a solid-liquid transition associated with complete melting; it can guide the choice of wax storage and application temperatures. The solid-solid temperature transition is related to the properties of the solid, that is, hardness and blocking temperature.

ASTM D36 Softening Point Of Bitumen
Two horizontal disks of bitumen, cast in shouldered brass rings, are heated at a controlled rate in a liquid bath while each supports a steel ball. The softening point is reported as the mean of the temperatures at which the two disks soften enough to allow each ball, enveloped in bitumen, to fall a distance of 25 mm (1.0 in.)

ASTM D1754 Thin Film Oven Test
this oven indicates approximate change in properties of asphalt during conventional hot-mixing at about 150℃ as indicated by viscosity,penetration,or ductility measurement,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 pm properties will occurs
