BS EN 12697-3:2013+A1:2018描述了从沥青混合料中回收可溶性沥青的试验方法 用于道路、机场或类似路面，其形式适合进一步测试。测试可以是 在松散或压实的沥青材料上进行。该程序适用于恢复 本欧洲标准为其参考方法的铺路级沥青。这个 分馏塔程序（见EN 12697-4）是含有 挥发性物质，如稀释沥青。对于聚合物改性沥青的回收，建议采用旋转蒸发器程序。交叉引用:EN 12697-1:2012EN 12594EN 12697-38EN 1426ISO 4259EN 1427EN ISO 4259包含以下内容:修订，2019年1月

BS EN 12697-3:2013+A1:2018 describes a test method for the recovery of soluble bitumen from bituminous mixtures used in road, airfield or similar pavements in a form suitable for further testing. The test can be undertaken on either loose or compacted asphalt materials. The procedure is suitable for the recovery of paving grade bitumens, for which materials this European Standard is the reference method. The fractionating column procedure (see EN 12697-4) is the reference method for mixtures containing volatile matter such as cut-back bitumen.For recovery of polymer modified bitumens, the rotary evaporator procedure is recommended.Cross References:EN 12697-1:2012EN 12594EN 12697-38EN 1426ISO 4259EN 1427EN ISO 4259Incorporates the following:Amendment, January 2019
