Foreword

This revised standard adopts the American Society for Testing and Materials standard ASTMD2042-01 "Determination of bituminous materials in trichlorethylene solubility Method "(in English). This standard redrafted according ASTMD2042-01. Suitable for China's national conditions, this standard when using ASTMD2042-01 made some modifications. This standard ASTMD2042-01 The main differences are as follows. --- Removed 1 filtration equipment assembly drawings, schematic increase suction filtration bottles, glass joints and Gooch crucible; --- Removed insoluble content of Formula 1 formula; Chapter 12 --- deleted the relevant content, using precision GB/T 11148-1989 requirements. This standard replaces GB/T 11148-1989 "Determination of the solubility of asphalt." This standard and GB/T 11148-1989 compared to primary To change the following. --- Increased provisions relating to security; --- 3.5 to 5.2 rubber tubing or fittings glass joints; --- 3.8 to 5.4 double ball vacuum pump or water pump; --- Increased suction flask, glass joints and schematic Gooch crucible; --- Remove the 4.2 "benzene, carbon tetrachloride"; --- In ASTMD2042-01 solubility formula instead of GB/T 11148-1989 solubility in Chapter 7 of the formula. This standard by the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) proposed. The standard by the China University of Petroleum (East China) Heavy Oil Research Institute. This standard was drafted. China University of Petroleum (East China) Heavy Oil Research Institute. The main drafters of this standard. Guoxiang, Zhang Xiaoying. This standard was first published in March 1989, this revision of the 1st amendment. Asphalt solubility assay

1 Scope

This standard does not involve the use of relevant safety requirements, standards, responsibility of the user to develop appropriate safety procedures before using the application.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 11147 bitumen sampling method

3 Method Summary

Samples were dissolved in trichlorethylene, filtered through a glass fiber filter paper, insolubles were washed, dried and weighed to calculate the solubility.

4 Significance and Uses

Asphalt trichlorethylene solubles content reflects its active ingredient content bonding.

5 Apparatus and materials

5.1 Gooch crucible. a top diameter of about 32mm, height of about 80mm; the lower part with a plug, carefully grind, with 34 standard ground close Cooperation. 5.2 glass joints. for Gooch crucible fixed suction filter flask, the upper part 34 standard ground, can cooperate closely with Gooch crucible; a lower portion After careful polishing, can cooperate closely with No. 24 standard ground. 5.3 suction flask. glass, conical, thick-walled, with a branch pipe, bottle of 24 standard ground, can cooperate closely with the glass joints. Gooch crucible, glass fittings and suction flask schematically in Figure 1. Millimeters 1 suction flask, glass joints and Gooch crucible schematic ......
