沥青混凝土渗透仪试验步骤:

★按规范要求制备沥青混合料(详见附录),按规范要求成型马歇尔试件。如采用芯样进行试验,用切割机将芯样上下两头切平,测量试件的平均高度和直径。

★将渗透试模的上盖卸下,将试件放入试模中间,清理试件表面,除去油污、粉尘等,避免试件周围与沥青结合不好而渗水,灌入热沥青密封试模与试件周边的缝隙。灌缝时应避免热沥青污

★染试件表面及沥青外流。待沥青冷至室温后,装好上盖, 拧紧螺栓。渗透试件装模后,应加以检查,确认试模密封良好、管道通畅。

★试验应采用蒸馏水或经过滤的清水,试验前用抽气法或煮沸法进行排气。试验时水温宜高于室温3℃~4℃。试验开始前应备够一次试验所需的用水。

Asphalt concrete permeameter test steps:

★ Asphalt mixture is prepared according to the specifications (see appendix for details), and Marshall test pieces are formed according to the specifications. If the core sample is used for the test, the upper and lower ends of the core sample are cut flat with a cutting machine, and the average height and diameter of the test piece are measured.

★ Remove the upper cover of the penetration test mold, place the test piece in the middle of the test mold, clean the surface of the test piece, remove oil, dust, etc., avoid the water around the test piece not being well bonded with the asphalt, and inject the hot asphalt to seal the test mold With the gap around the test piece. Avoid hot asphalt pollution when filling joints

★ Dyeing test piece surface and asphalt flow out. After the asphalt has cooled to room temperature, install the cover and tighten the bolts. After the penetration test piece is installed, it should be inspected to confirm that the test mold is well sealed and the pipeline is unobstructed.

★ The test should use distilled water or filtered water. Exhaust by the air extraction method or boiling method before the test. The water temperature should be 3 ℃ ~ 4 ℃ higher than the room temperature during the test. Before starting the test, sufficient water for one test should be prepared.
