四個方法提高瀝青混合料的質量

來源:http://m.yuanchuodian.cn/ 日期:2022-12-28
瀝青混合料質量的好壞很大程度影響著路面質量,所以如何確保瀝青混合料的質量,就成為大量瀝青混凝土攪拌站關注的焦點,下面濟南瀝青料廠家就來為您講解。
The quality of asphalt mixture greatly affects the pavement quality, so how to ensure the quality of asphalt mixture has become the focus of many asphalt concrete mixing plants. Now, Jinan asphalt manufacturer will explain it to you.
一、提高瀝青質量:瀝青保養
1、 Improve asphalt quality: asphalt maintenance
其中應該根據公路等級、氣候條件、路面類型、交通量大小的不同而選擇。夏季高溫、高速、重載、長坡路面應該選擇粘度大的瀝青,反之,氣候寒冷、交通量小則可選用粘度小的瀝青。
It shall be selected according to different highway grades, climatic conditions, pavement types and traffic volumes. Asphalt with high viscosity should be selected for pavement with high temperature, high speed, heavy load and long slope in summer. On the contrary, asphalt with low viscosity can be selected for pavement with cold climate and small traffic volume.
其中每批瀝青均應按技術規范進行抽樣檢驗,以保證質量,其中瀝青的管理要注意不同來源的瀝青要分別存放,不能混雜,防止污染;其貯存溫度在施工期不高于170℃,不低于150℃;長期存放時應在低溫下進行。
Each batch of asphalt shall be sampled and inspected according to the technical specifications to ensure the quality. For asphalt management, attention shall be paid to storing asphalt from different sources separately and not mixing them to prevent pollution; The storage temperature shall not be higher than 170 ℃ and not lower than 150 ℃ during the construction period; Long term storage shall be conducted at low temperature.
二、瀝青提高質量:集料
2、 Asphalt quality improvement: aggregate
集料是瀝青混凝土的骨架,是影響瀝青混凝土強度的主要因素,在選料過程中,要注意減少集料級配的變異性,把控制集料級配關鍵的篩孔設為破碎機的受控篩孔,以此保證集料級配的穩定性。
Aggregate is the skeleton of asphalt concrete and the main factor affecting the strength of asphalt concrete. In the process of material selection, attention should be paid to reducing the variability of aggregate grading, and the key screen hole for controlling aggregate grading should be set as the controlled screen hole of the crusher, so as to ensure the stability of aggregate grading.
要注意不可使用針片狀的集料。集料的含泥量也會影響集料和瀝青的粘附性能和混合料的穩定性,所以在拌制混合料前,要清潔含泥的集料,堆放在料場的集料要覆蓋,防止粉塵污染。
Care shall be taken not to use needle shaped aggregates. The mud content of aggregate will also affect the adhesion between aggregate and asphalt and the stability of the mixture. Therefore, before mixing the mixture, the aggregates containing mud should be cleaned, and the aggregates stacked in the stock yard should be covered to prevent dust pollution.
濟南瀝青料
三、提高瀝青質量:礦粉
3、 Improve asphalt quality: mineral powder
礦粉對瀝青混合料的骨料膠結起著重要作用,并非單純的填充作用,在相同的瀝青用量下,礦料的表面積越大,形成的瀝青膜越薄,結構瀝青比重越大,瀝青混合料粘聚力越強。礦粉須是石灰巖或者巖漿巖中強基性巖石磨碎后的礦粉,加工前要保證原石料的粘土被清除,注意保存時要注意防水、防潮。
Mineral powder plays an important role in the aggregate cementation of asphalt mixture, rather than simply filling. With the same asphalt content, the greater the surface area of mineral aggregate, the thinner the asphalt film formed, the greater the proportion of structural asphalt, and the stronger the cohesion of asphalt mixture. The mineral powder must be the mineral powder ground by the strong basic rock in limestone or magmatic rock. Before processing, ensure that the clay of the raw stone is removed, and pay attention to waterproof and moisture-proof during storage.
四、提高瀝青質量:拌和溫度控制
4、 Improve asphalt quality: mixing temperature control
如果混合料溫度過低,就會影響攤鋪和碾壓質量,造成拌合不均勻和碾壓困難。一般熱拌瀝青混合料的拌合溫度在130~160℃為宜。
If the mixture temperature is too low, the paving and rolling quality will be affected, resulting in uneven mixing and rolling difficulties. Generally, the mixing temperature of hot mix asphalt mixture should be 130~160 ℃.
其中改性瀝青拌合溫度宜比普通瀝青混合料拌合溫度要提高10~20℃,改性瀝青混合料在貯存過程中溫降應小于10℃,集料的溫度應該比瀝青溫度高10~30℃,儲料在儲料倉時間不得超過72小時。
The mixing temperature of modified asphalt should be 10~20 ℃ higher than that of ordinary asphalt mixture, the temperature drop of modified asphalt mixture during storage should be less than 10 ℃, the temperature of aggregate should be 10~30 ℃ higher than that of asphalt, and the storage time in the storage bin should not exceed 72 hours.
