　　瀝青料是常見(jiàn)的施工材料，使用頻率還是比較高的，當(dāng)然施工期間少不了一定環(huán)節(jié)或者過(guò)程的發(fā)揮作用，比如說(shuō)瀝青料拌合質(zhì)量就非常的關(guān)鍵，那么會(huì)受到什么因素影響呢？

　　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?

　　原材料質(zhì)量的影響

　　粗骨料中的軟石和片狀顆粒會(huì)對(duì)瀝青材料的質(zhì)量產(chǎn)生很大影響；細(xì)骨料包括石屑、人造砂和天然砂。一般來(lái)說(shuō)，應(yīng)謹(jǐn)慎使用。人造機(jī)制砂是一種理想的路面細(xì)骨料。天然沙子通常是酸性石頭，對(duì)瀝青的附著力很差。應(yīng)與其他細(xì)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.

　　軋制質(zhì)量控制

　　軋制質(zhì)量與軋制溫度有直接關(guān)系。由于攤鋪后瀝青材料的溫度不斷下降，特別是在攤鋪后4～15分鐘內(nèi)，溫度下降可達(dá)每分鐘1～5攝氏度，所以要把握好碾壓時(shí)機(jī)，及時(shí)碾壓。如果遇到低溫、高濕、大風(fēng)等氣候條件，會(huì)縮短有效軋制時(shí)間，增加軋制難度。在軋制過(guò)程中，保持恒定的軋制速度也很重要。

　　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.

　　攪拌溫度控制

　　濟(jì)南瀝青料溫度過(guò)低，會(huì)影響攤鋪和碾壓的質(zhì)量，也會(huì)造成碾壓困難。但是，如果溫度過(guò)高，會(huì)導(dǎo)致瀝青老化變硬，使瀝青材料的性能變差。因此，混合時(shí)應(yīng)嚴(yán)格控制混合溫度。建議批式攪拌設(shè)備每盤(pán)攪拌時(shí)間在45秒到50秒之間，其中干混時(shí)間不少于5秒到10秒，以瀝青材料混合均勻?yàn)闃?biāo)準(zhǔn)。

　　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.
