Precautions and Instructions for Use of the Asphalt Mixture Compaction Tester
1. First, connect the three plugs at the back of the cabinet properly. The “motor” should be connected to the motor input port on the cabinet, the “non-contact proximity switch” should be connected to the counting port, and the “power supply” should be connected to the power port. At the same time, make sure the neutral wire is properly connected.

Operating Procedures for the Asphalt Softening Point Tester
■Place the metal ring on a glass plate coated with a glycerin-talc powder release agent (glycerin:talc powder = 2:1). Heat the asphalt (for petroleum asphalt, heat to ≤ the estimated softening point + 90℃; for coal asphalt, heat to ≤ the estimated softening point + 50℃), stir it thoroughly, sieve it, and then pour it into the metal ring so that its surface slightly exceeds the top of the ring.

Introduction to the Parameters of the Asphalt Extensometer
This test is applicable for evaluating the elastic recovery performance of thermoplastic rubber-modified asphalt polymers—that is, determining the percentage of deformation recovery through the sieve holes after the specimen has been elongated to a specified length using a ductility tester. Supplied by Hebei Dahong Testing Instrument Co., Ltd. Unless otherwise specified, the test temperature is 25℃, and the tensile rate is 5 cm/min ± 0.25 cm/min.

Technical Parameters and Specifications of the Asphalt Penetration Tester
The asphalt penetration tester is designed and manufactured in accordance with the technical requirements specified in the industry standard JTGE20-2011 issued by the Ministry of Transport. This method is applicable to determining the penetration of road petroleum asphalt, polymer-modified asphalt, as well as the penetration of residue remaining after distillation or emulsification of liquid petroleum asphalt, measured in 0.1 mm increments. The standard test conditions are 25℃, with a load of 100 g and a penetration time of 5 seconds.
