摘要
为隧道路用沥青的阻燃性能提供可行的比较测试方法,借鉴化工等行业的氧指数测试方法,对沥青持续燃烧能力进行初步试验,分析了沥青氧指数测试的有关影响因素,并重点对试样温度、试样量以及燃烧时总气流量等进行了分析和测试。认为沥青的持续燃烧能力可以通过氧指数评价,但必须提供对应的参数说明。建议对测试仪器设备进行改造,以适应沥青氧指数的检测。
In order to provide efficiency test methods for asphalt character of persisting burning in the tunnel pavement, the test methods for asphalt character of persisting burning were discussed based on the oxygen index test methods used in the chemical industry. Then the relevant influence factors, such as sample temperature, sample weight and flux, were analyzed. With the calculation that the oxygen index with parameters can be used to evaluate asphalt character of persisting burning, and the test equipments should be adjusted to fit the test methods.
