我段近年来在油路施工中,对沥青混合料油石比曾使用了一种直接与标准油石比混合料样品对比检定的方法。该法无需复杂的设备,手续简便,检定结果尚为准确,方法极其快速。现介绍如下: 一、检定方法简介:事前取用备妥待用的矿料和沥青,准确地配制出包含施工设定沥青混合料油石比在内的一系列标准油石比的混合料样品,并将其分放在特制的样品箱里作为对比的标准样品。检定工作是在施工现场,对拌合场生产出的沥青混合料,随时 In recent years, during construction of the oil pipeline, I have used a method of comparing the direct and standard samples of masonry to asphalt mixtures. The method without complex equipment, procedures are simple, the test results are accurate, the method is extremely fast. Now introduced as follows: First, the test method Description: In advance access to the ready-to-use mineral aggregate and bitumen, accurate preparation of asphalt mixture containing asphalt stone ratio, including a series of standard oilstone mixture samples, and Place it in a special sample box for comparison as a standard sample. Verification work is at the construction site, the mixing plant to produce asphalt mixture, at any time
