旋转式沥青回收仪操作规程:

准备工作

★ 准备沥青混合料试样,一次用量应预计可获得回收沥青试样80g~120g,不足沥青试验项目需要时可分次回收后混合使用。沥青混合料若是从路上钻取的试样,宜用电风扇吹干水分后再用微波炉或烘箱内加热,使成松散状态,但加热温度不得超过100℃,从开始加热至试样松散的试件不得超过30min。

★ 按本规程规定的方法测定沥青混合料密度及空隙率等各项物理指标。

★按本规程方法将沥青混合料用离心法抽提出沥青溶液,至抽提液达澄清透明为止

★将全部沥青抽提液分次装入离心管中,用高速离心分离法清除抽提液中的矿粉部分,施加离心力770G以上,离心分离的时间不少于30min。

★将干净的抽提液取出一部分置减压过滤器的滤纸上过滤,一边抽气一边向滤纸上加新的三氯乙烯溶液洗净。仔细观察滤纸上还有没有矿粉颗粒,检验高速离心分离法清除矿粉是否干净。如有应重复上述的步骤延长分离时间,直至确认抽提液中没有矿粉为止。

★将旋转蒸馏回收装置接妥,接头均应密封,不漏气。

★ 将加热装置的油浴调节至50℃±5℃。

★ 将沥青抽提液全部(约350mL~400mL)装入洁净的1000mL旋转烧瓶中,用少量溶剂清洗后也并入瓶中。

★开动真空泵或抽气机,使整个系统形成负压,真空度97.4kPa(719mmHg)以下。

★开动旋转烧瓶,在不浸入加热油浴的状态下,以约50r/min的速度旋转5min~10min。

★在保持上述速度旋转的状态下,缓慢地将旋转烧瓶底部浸入已达50℃±5℃的油浴中,烧瓶内的溶剂开始蒸发,当冷凝装置冷却的溶液流入溶剂回收烧瓶达到稳定状态后,逐渐增加旋转速度。并增大旋转烧瓶浸入油浴的加热面积,加快蒸馏速度。直至无溶剂汽凝回收时,蒸馏结果,将旋转速度降低至20r/min。

★旋转烧瓶继续保持旋转状态,同时将油浴升温,在15min内上升至155℃±2℃,再在此状态下保持15min,然后开放CO2阀门,以1000mL/min的流速通过2min。

★关闭CO2阀门,逐渐使旋转瓶内恢复至常压,停止旋转烧瓶旋转,离开油浴,拆开装置。

★迅速倒出烧瓶内的残留沥青,进行回收沥青的各项试验。

★对回收沥青进行粘度、针入度、软化点、组分分析等各项试验方法与原样沥青的试验方法相同。

Aberson method asphalt recycling instrument operating procedures:
Ready to work
★ Prepare the asphalt mixture sample. The primary asphalt should be expected to obtain 80g~120g of recycled asphalt samples. When the asphalt test project is needed, it can be recycled after mixing. If the asphalt mixture is sampled from the road, it should be dried with an electric fan and then heated in a microwave oven or oven to make it loose. However, the heating temperature should not exceed 100 °C. From the start of heating to the loose test of the sample. The item must not exceed 30 minutes.
★ Determine the physical properties of asphalt mixture density and void ratio according to the method specified in this regulation.
★ According to the method of this procedure, the asphalt mixture is extracted by centrifugation to the asphalt solution until the extract is clear and transparent.
★ All the asphalt extracts are packed into the centrifuge tube in turn, and the part of the ore powder in the extract is removed by high-speed centrifugation. The centrifugal force is applied above 770G, and the time of centrifugation is not less than 30min.
★ Take a clean extract and remove some of the filter paper from the filter. After pumping, add a new solution of trichloroethylene to the filter paper. Carefully observe that there are no ore particles on the filter paper, and check whether the ore powder is clean by high-speed centrifugal separation. If necessary, repeat the above steps to extend the separation time until it is confirmed that there is no mineral powder in the extract.

★ Connect the rotary distillation recovery unit and the joints should be sealed and airtight.
★ Adjust the oil bath of the heating unit to 50 °C ± 5 °C.
★ Put all the asphalt extract (about 350mL~400mL) into a clean 1000mL spinner flask, and then wash it with a small amount of solvent and then into the bottle.
★ Start the vacuum pump or air extractor to make the whole system form a negative pressure with a vacuum of 97.4 kPa (719 mmHg) or less.
★ Turn the rotating flask and rotate it at a speed of about 50r/min for 5min~10min without immersing in the heating oil bath.
★ While maintaining the above-mentioned speed rotation, slowly immerse the bottom of the rotating flask in an oil bath of 50 ° C ± 5 ° C, the solvent in the flask begins to evaporate, and when the solution cooled by the condensing device flows into the solvent recovery flask to reach a steady state, , gradually increase the rotation speed. And increase the heating area of the rotating flask immersed in the oil bath to speed up the distillation. Until the solvent-free coagulation recovery, the distillation results in a reduction in the rotational speed to 20 r/min.
★ The rotating flask was kept in a rotating state. At the same time, the oil bath was warmed up, raised to 155 °C ± 2 °C in 15 min, and kept in this state for 15 min, then the CO2 valve was opened and passed at a flow rate of 1000 mL/min for 2 min.
★ Close the CO2 valve, gradually return the inside of the rotating bottle to normal pressure, stop the rotation of the rotating flask, leave the oil bath, and disassemble the device.
★ Quickly pour out the residual asphalt in the flask and carry out various tests for the recovery of asphalt.
★ The test methods for viscosity, penetration, softening point and composition analysis of recycled asphalt are the same as those for the original asphalt.
