山东省内道路石油沥青质量统计与总览

Quality Statistics and Overview of Petroleum Asphalt in Shandong Province

该文基于山东省交通科学研究院2005~2016年近12年沥青检测数据库,选取气候分区(1-3)高等级公路所常用70#道路石油沥青为统计样本,分析道路石油沥青(70#)各项指标的时间演进过程。分析认为,相较于12年前,在原油性质及经济效益的双重作用下,目前道路石油沥青(70#)性能发生了重大变化;对沥青性能检测提出更高的要求,现有的检测方法已不能满足实际施工需要,需要引进新的快速高效的检测评价方法,科学地指导工程建设。

This paper is based on the asphalt detection database of the last 12 years from 2005 to 2016 in Shandong province.Grade 70#petroleum asphalt commonly used by highway at climate partition(1-3)was selected as statistical sample.It is to get the systematic analysis of the changes of petroleum asphalt(grade70#)with the evolution of time.Currently,under the dual function of the crude oil properties and economic benefit,great changes have taken place in the performance of petroleum asphalt(grade70#)compared with 12 years ago.The higher request with the performance testing was put forward.The existing detection methods can not meet the needs of the actual construction.To guide the engineering practice sciencificly,the efficient testing evaluation method was to be introduced.
