济南沥青料拌合质量受什么因素影响
来源：/ 日期：2022-05-05
沥青料是常见的施工材料，使用频率还是比较高的，当然施工期间少不了一定环节或者过程的发挥作用，比如说沥青料拌合质量就非常的关键，那么会受到什么因素影响呢？
Asphalt is a common construction material, the use frequency is still relatively high, of course, during the construction period, certain links or processes play a role, such as asphalt mixing quality is very key, so what factors will affect it?
原材料质量的影响
粗骨料中的软石和片状颗粒会对沥青材料的质量产生很大影响；细骨料包括石屑、人造砂和天然砂。一般来说，应谨慎使用。人造机制砂是一种理想的路面细骨料。天然沙子通常是酸性石头，对沥青的附着力很差。应与其他细骨料配合使用。
The impact of raw material quality
Soft stone and flake particles in coarse aggregate have a great influence on the quality of asphalt materials. Fine aggregate includes stone chips, artificial sand and natural sand. In general, it should be used with caution. Artificial machine-made sand is an ideal aggregate for road surface. Natural sand is usually an acidic stone with poor adhesion to asphalt. Should be used with other fine aggregate.
轧制质量控制
轧制质量与轧制温度有直接关系。由于摊铺后沥青材料的温度不断下降，特别是在摊铺后4～15分钟内，温度下降可达每分钟1～5摄氏度，所以要把握好碾压时机，及时碾压。如果遇到低温、高湿、大风等气候条件，会缩短有效轧制时间，增加轧制难度。在轧制过程中，保持恒定的轧制速度也很重要。
Rolling quality control
Rolling quality is directly related to rolling temperature. Because the temperature of asphalt material decreases continuously after paving, especially in 4 to 15 minutes after paving, the temperature can drop up to 1 to 5 degrees Celsius per minute, so we must grasp the timing of rolling, rolling in time. In case of low temperature, high humidity, strong wind and other climatic conditions, the effective rolling time will be shortened and the rolling difficulty will be increased. It is also important to maintain a constant rolling speed during the rolling process.
搅拌温度控制
济南沥青料温度过低，会影响摊铺和碾压的质量，也会造成碾压困难。但是，如果温度过高，会导致沥青老化变硬，使沥青材料的性能变差。因此，混合时应严格控制混合温度。建议批式搅拌设备每盘搅拌时间在45秒到50秒之间，其中干混时间不少于5秒到10秒，以沥青材料混合均匀为标准。
Stirring temperature control
Ji 'nan asphalt material temperature is too low, will affect the quality of paving and rolling, will also cause rolling difficulties. However, if the temperature is too high, it will lead to aging and hardening of asphalt, so that the performance of asphalt material becomes poor. Therefore, the mixing temperature should be strictly controlled when mixing. It is recommended that the mixing time of batch mixing equipment should be between 45 seconds and 50 seconds for each plate, and the dry mixing time should be no less than 5 seconds to 10 seconds. The asphalt material should be evenly mixed as the standard.
Ji 'nan asphalt mixing quality by what factors? In this paper, three aspects of the impact, I hope to help your construction, more relevant content you can come to our website to consult.
