Asphalt Concrete with Gilsonite[J]. 付海英

The article introduced the category of natural bitumen and the characteristic of gilsonite. 介紹了天然瀝青的種類與天然巖瀝青的特點。

Gilsonite in mass is ashiny , blac substance similar in apperarnace to the mineral obsidian . 由于其獨特的兼容性，硬瀝青常被用于硬化軟石油產品。整體的硬瀝青是一種有光澤的黑色物質，外表類似于黑曜石礦物。它易碎并可被輕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. 詳細介紹了GILSONITE法測定乳膠漆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，通過DSR、BBR、Brookfield旋轉粘度試驗，用PG分級評價體系對巖瀝青改性瀝青進行比較分析。
