加纖維瀝青混凝土的拌和要求

來源:http://m.yuanchuodian.cn/ 日期:2022-12-19
加纖維瀝青混凝土的施工方法與傳統瀝青混凝土的施工基本相同,分為進場材料檢驗、拌和設備的選型、拌和、攤鋪和碾壓一個工序進行,下面濟南瀝青混凝土生產廠家就來講講加纖維瀝青混凝土的拌和要求。
The construction method of fiber reinforced asphalt concrete is basically the same as that of traditional asphalt concrete, which is divided into one process: inspection of incoming materials, selection of mixing equipment, mixing, paving and rolling. Next, Jinan asphalt concrete manufacturer will talk about the mixing requirements of fiber reinforced asphalt concrete.
1、確定每盤熱料倉的配合比,計算出每盤混合料的質量,根據目標配合比確定的纖維用量計算每盤混合料中投放的纖維質量,然后按此質量對進場的纖維進行分裝,包裝袋采用市場上常見的聚乙烯塑料袋即可。分裝過程中,保證稱量的準確性。纖維的摻加如示意圖:
1. Determine the mix proportion of each tray of hot material bin, calculate the quality of each tray of mixture, calculate the quality of fiber put into each tray of mixture according to the fiber consumption determined by the target mix proportion, and then pack the incoming fibers according to this quality. The packaging bags can be polyethylene plastic bags commonly used in the market. Ensure the accuracy of weighing during subpackaging. The addition of fiber is shown in the schematic diagram:
2、瀝青混合料應按設計瀝青用量進行試拌,試拌后取樣進行馬歇爾試驗,并將其試驗值與室內配合比試驗結果進行比較,驗證設計瀝青用量的合理性,必要時可作適當調整:
2. The asphalt mixture shall be trial mixed according to the design asphalt dosage. After trial mixing, samples shall be taken for Marshall test, and the test value shall be compared with the indoor mix proportion test results to verify the rationality of the design asphalt dosage. If necessary, appropriate adjustments can be made:

3、確定適宜的拌和時間。對于普通的瀝青混合料,間歇式拌和設備每盤拌和時間為30~60秒,推薦的拌和時間為干拌25~30秒,濕拌30秒,以混合料拌和均勻,纖維和瀝青混合料裹覆良好為準;
3. Determine the appropriate mixing time. For ordinary asphalt mixture, the mixing time of each batch of intermittent mixing equipment is 30-60 seconds. The recommended mixing time is 25-30 seconds for dry mixing and 30 seconds for wet mixing. The mixture shall be evenly mixed and the fiber and asphalt mixture shall be well coated;
4、確定適宜的拌和與出廠溫度。瀝青(均指石油瀝青,下同)的加熱溫度宜為130℃~160℃,加熱不宜超過6小時,且當天加熱宜當天用完,不宜多次加熱,以免老化砂石加熱溫度為140℃~170℃,礦分不加熱。瀝青混合料的出廠溫度宜為130℃~160℃,當使用改性瀝青時,應比上述溫度的高限再提高10℃~15℃,纖維的摻加不必進行溫度調整。
4. Determine appropriate mixing and factory temperature. The heating temperature of asphalt (all refer to petroleum asphalt, the same below) should be 130 ℃~160 ℃, and the heating should not exceed 6 hours. The heating should be used up on the same day, and should not be repeated, so as to avoid the heating temperature of aging sand and gravel is 140 ℃~170 ℃, and the mineral is not heated. The factory temperature of asphalt mixture should be 130 ℃~160 ℃. When modified asphalt is used, it should be 10 ℃~15 ℃ higher than the upper limit of the above temperature. It is unnecessary to adjust the temperature when adding fiber.
此外加纖維瀝青混凝土路面成型過程中一般不會形成油斑,顏色外觀與普通瀝青混凝土路面基本相同。更多相關內容就來我們網站http://m.yuanchuodian.cn進行咨詢了解吧!
