The article introduced the category of natural bitumen and the characteristic of gilsonite. 介绍了天然沥青的种类与天然岩沥青的特点。
Gilsonite in mass is ashiny , blac substance similar in apperarnace to the mineral obsidian . 由于其独特的兼容性，硬沥青常被用于硬化软石油产品。整体的硬沥青是一种有光泽的黑色物质，外表类似于黑曜石矿物。它易碎并可被轻易碾碎成茶褐色粉末。
This paper has described in detail the principle, procedure and limitation of the GILSONITE method for determination of the CPVC of latex paint. 详细介绍了GILSONITE法测定乳胶漆CPVC值的原理、使用方法及其局限性。
In the second part, the performances of gilsonite modified bitumen are compared and analyzed with PG appraisal system through DSR, BBR and Brookfield revolving viscosity tests. 第二，通过DSR、BBR、Brookfield旋转粘度试验，用PG分级评价体系对岩沥青改性沥青进行比较分析。
The goal of this article is to research and evaluate the performance of gilsonite, to provide the technical basis for applications of this kind of material. 本文目的是研究和评价岩沥青路用性能，为岩沥青的实际工程应用提供技术依据。
