Introduction to asphalt pavement seepage meter:

The penetration of the road surface, a standard of the road surface quality, the instrument can be used to measure the amount of water seepage per unit time under the certain variable head of the asphalt pavement (called the seepage volume of the road surface). For on-site measurement and experimental research for the construction road and maintenance department. The instrument is exquisitely processed and has high test accuracy. It is suitable for determining the water permeability coefficient of asphalt mixture pavement and roller compacted asphalt mixture test piece. In order to verify the water seepage performance of the pavement and the mix ratio of the asphalt mixture.

路面水分渗透仪使用方法：

★选点：在路面上选好点，用扫帚和钢丝刷将测点上火土杂物清除干净。

★按底座大小在底座上抹一点腻子，将仪器底座按上并拧紧，抹实腻子，不使漏水。

★将铲有少量红墨水的水灌入仪器中，直至小量筒上端溢水孔为(至600mm高度为止)，从开始读数加水到开始读数应在3秒钟内完成。

★水达到预定水位后(600mm)即开动秒表，每30秒钟记一次水位高度，直到3分钟为止。

Road moisture infiltration instrument use method:

★Selection point: Select a good point on the road surface, and use a broom and wire brush to remove the fire and dirt from the measuring point.

★ Apply a little putty on the base according to the size of the base, press the base of the instrument and tighten it, and smear the putty to prevent water leakage.

★Pour water with a small amount of red ink into the instrument until the overflow hole at the top of the small cylinder is (up to 600mm height). The reading should be completed within 3 seconds from the start of reading water.

★After the water reaches the predetermined water level (600mm), the stopwatch is activated, and the water level is recorded every 30 seconds until 3 minutes.

路面水分渗透仪操作规程：

★将放置于坚实平面上的试件或待测试的路面清扫干净。

★放上标记环，用粉笔沿内环和外环分别画出标记，取下标记 环则试件表面或路面上也就留下了一个内环Φ150mm 外环为Φ 220mm 的两个同心圆。

★将标准环放在同心圆内，并使内环标记与标准环底面相吻合

★检查同心圆是否有构造深度较大的部位，如有必须先用密封 剂对这些部位的纹理深度进行填充， 以防止渗水试验时水通过这些表 面纹理渗出，从而影响到试验结果。

★在内外标记环之间抹一薄层密封材料，并用刮刀修补成内径 Φ150mm 外径为Φ220mm 厚约 3mm 的密封材料环， 修补时应压住面 积标准环使之不能移位。

★将渗水仪用力压在密封材料上，使渗水仪底座与密封材料环 吻合，加上 2 块配重块，以防压力水从底座与路面之间流出。

★关闭仪器阀门，向仪器阀注水，注满至上标线 O 的位置。

★迅速将开关全部拧开，待水面下降 100mL 时开动墨水， 使水变成淡红 秒表，每隔 60S，读记量筒上水位刻度一次，至水面下降 500mL 时 为止。

★按以上步骤在同一个检测路段选择 5 个测点测定渗水系 数。取其平均值为测试结果。

Pavement moisture permeation instrument operating procedures:

★ Clean the test piece placed on a solid surface or the road surface to be tested.

★ Put the marking ring, draw the mark along the inner ring and the outer ring with chalk, and remove the marking ring. Then the inner surface of the test piece or the road surface will have two concentric circles with an inner ring of Φ150mm and an outer ring of Φ 220mm.

★ Place the standard ring in the concentric circle and match the inner ring mark to the bottom of the standard ring

★ Check whether the concentric circles have a large depth of construction. If it is necessary to first fill the texture depth of these parts with a sealant to prevent water from seeping through these surface textures during the water penetration test, thus affecting the test results.

★ Apply a thin layer of sealing material between the inner and outer marking rings, and repair it with a scraper into a ring of sealing material with an inner diameter of Φ150mm and an outer diameter of Φ220mm and a thickness of about 3mm. When repairing, the standard ring should be pressed so that it cannot be displaced.

★ Press the water osmometer on the sealing material to make the base of the water osmosis meter match the sealing material ring, and add 2 weights to prevent pressure water from flowing out between the base and the road surface.

★ Close the instrument valve, fill the instrument valve with water, and fill it to the position of the upper marking line O.

★ Quickly unscrew the switch. When the water level drops by 100mL, start the ink and make the water turn into a reddish stopwatch. Every 60S, read the water level on the measuring cylinder once, until the water level drops by 500mL.

★ According to the above steps, select 5 measuring points on the same detection section to determine the water permeability coefficient. Take the average value as the test result.
