I. Introduction

• GD-2806E Asphalt Softening Point Test by Ring And Ball Apparatus is designed and made as per the National Standard of People's Republic of China GB/T4507 "Test Methods for Softening Point of Asphalt" and T0606"Asphalt Softening Point Test (Ring and Ball Methods)" in the Industry Standard of People's Republic of China JTJ052 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the softening point of asphalt, tar, liquid asphalt and other types of asphalt. It is the best choice of asphalt manufacturers, highway and bridge construction companies, college and universities, and research and development departments.

• GD-2806E Asphalt Softening Point Test by Ring And Ball Apparatus adopts microcomputer controlling technology, linear heating and automatic stirring working mode, it can determine two samples at the same time and it can show test results automatically. It is convenient, efficient, and reliable. It is the desired instrument for laboratory to determine the softening point of asphalt.
