Abstract

The invention discloses an asphalt softening point test sample preparation device. The asphalt softening point test sample preparation device comprises a sampling ring, a lower substrate, an upper cover plate and a side plate. The lower substrate is provided with a plurality of groove, and the upper cover plate is capable of rotating around the side plate. Hot asphalt can be extruded by the aid of the upper cover plate to realize one-time forming of the hot asphalt with the smooth surface flush with the upper end face of the sampling ring, adoption of a heat knife for secondary trimming is avoided, and accordingly generation of a great quantity of asphalt fume is avoided, and environment pollution is avoided as well while physical health of staffs is protected from damages. In addition, simultaneous one-time forming of multiple samples is realized, so that sample preparation efficiency is improved, and yield is increased. Furthermore, the asphalt softening point test sample preparation device is simple in structure, low in processing and manufacturing cost and easy in popularization and application.

Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to a sample preparation device for test samples of asphalt softening point. Background technique [0002] Asphalt softening point refers to the temperature at which the asphalt specimen is softened by heat and sags to a certain extent, which is used to reflect the viscosity, high temperature stability and temperature sensitivity of asphalt. Different asphalts have different softening points. The softening point of asphalt used in engineering should not be too low or too high, otherwise it will melt in summer and be brittle and difficult to construct in winter. [0003] At present, the softening point of asphalt is mostly determined by the ring and ball method. The general operation steps of the ring and ball method are: the sample is placed in a sample ring of a specified size, a steel ball of a specified size and quality is placed on it, and it is placed in water (5°C) or ...
