浇注式沥青混合料是一种在高温下具有流动性、无需碾压的沥青混合料,其拌合站出料温度一般为220~250℃,且矿粉含量一般在25%左右,同时绝大多数沥青拌合站不具备矿粉加热功能,石料的温度需要加热到300~340℃才能保证出料温度。笔者以参与的数十座钢桥面浇注式沥青混合料生产对拌合站的影响进行分析,探讨高温状态下拌合站的影响状况。
Pouring asphalt mixture is a fluid with high temperature, without rolling asphalt mixture, the mixing station discharge temperature is generally 220 ~ 250 ℃, and slag content is generally about 25%, while the vast Most asphalt mixing plant does not have the slag heating function, the temperature of the stone needs to be heated to 300 ~ 340 ℃ to ensure the discharge temperature. I participated in the dozens of steel bridge casting asphalt mixture production of the impact of the mixing station to analyze the impact of high temperature mixing station status.
