根据1990年交通标准化计划,由交通部标准所、辽宁省义县公路机械仪器厂负责起草的行业标准《光电式沥青含量测定仪》(以下简称《光电仪》),现已通过审查并完成报批。下面对该标准的有关问题作简要说明。一、概述沥青含量是指沥青混合料中沥青与矿(石)料之质量比,习惯上称作油石比,它是评价沥青混合料质量的重要技术指标。沥青含量是否符合规定要求,对路面的使用性能和寿命有很大的影响。因此,在生产沥青
According to the traffic standardization plan of 1990, the industry standard “Photoelectric Asphalt Content Analyzer” (hereinafter referred to as “Photoelectricity Meter”) drafted by the Ministry of Communications Standards Institute and Liaoning Province Yixian Highway Machinery Instrument Factory has passed the examination and approval . The following is a brief description of the standard related issues. I. Overview Asphalt content refers to the asphalt mixture of asphalt and ore (stone) material quality ratio, commonly known as the stone ratio, it is to evaluate the quality of asphalt mixture important technical indicators. Asphalt content meets the requirements, the use of the road performance and life expectancy have a great impact. Therefore, the production of asphalt
