沥青混凝土斜坡流淌值试验仪仪器的组成：

★钢板制成：主机1台,可放置6个试件。

★万用电表1个。

★位移计：精度0.01mm6个。

Composition of asphalt concrete slope flow tester instrument:

★ Steel plate: 1 host machine, 6 test pieces can be placed.

★ 1 multimeter.

★ Displacement meter: 6 pcs.

沥青混凝土斜坡流淌值试验仪试验步骤：

★按规定制备沥青混合料,按规定成型马歇尔试件,每组6个,高度63.5mm±1.3mm。从现场钻取的芯样,应加工成直径为100mm±3mm,高度为63.5mm±1.3mm的试件。

★试件成型后,在室温条件下放置24h,测量试件高度。

★采用耐高温的高强度黏结剂将每个试件粘贴的斜坡流淌仪上,在距试件底部50mm处用高强度黏结剂粘贴8mm×3mm×1mm的铜片,在铜片的一根导线,在流淌仪板面上有一根公用导线：各铜片的导线及公用导线分别与万用表两**连接,调整位移计位置,使位移计测头与铜片接触,检验电路是否接通。位移计距离斜坡面垂直距离50mm。

★将斜坡坡度调整至设计规定的坡度,如无规定,斜坡坡度科采用1:1.7。

★将烘箱升至试验温度,温度误差控制在±1℃。试验温度可按工程实际情况确定,如无规定,可采用70℃。

★斜坡流淌仪放入烘箱前,调整位移计,读取各试件的初读数Uo,然后将斜坡流淌仪平稳放入已升温至试验温度的烘箱内。

★恒温48h,读取各试件的变形值Ue。

Test steps of asphalt concrete slope flow tester:

★ Asphalt mixture is prepared according to the regulations, and Marshall test pieces are formed according to the regulations, 6 in each group, and the height is 63.5mm ± 1.3mm. Core samples drilled from the site should be processed into test pieces with a diameter of 100mm ± 3mm and a height of 63.5mm ± 1.3mm.

★ After forming the test piece, place it at room temperature for 24h and measure the height of the test piece.

★ Use a high-temperature resistant high-strength adhesive to attach each test piece to the slope flow meter. At a distance of 50mm from the bottom of the test piece, use a high-strength adhesive to paste a 8mm × 3mm × 1mm copper sheet. There is a common wire on the surface of the flow meter: the copper wire and the common wire are respectively connected to the two meters of the multimeter, adjust the position of the displacement meter, make the displacement meter contact the copper plate, and check whether the circuit is connected. The displacement meter is 50mm perpendicular to the slope surface.

★ Adjust the slope of the slope to the slope specified in the design. If there is no stipulation, the slope section will use 1: 1.7.

★ Raise the oven to the test temperature, and the temperature error is controlled at ± 1 ℃. The test temperature can be determined according to the actual situation of the project. If there is no stipulation, 70 ℃ can be used.

★ Before the slope flow meter is placed in the oven, adjust the displacement meter, read the initial reading Uo of each test piece, and then put the slope flow meter into the oven that has warmed up to the test temperature.

★ Constant temperature 48h, read the deformation value Ue of each test piece.

沥青混凝土斜坡流淌值试验仪试验结果处理：

★斜坡流淌值按式计算,**至0.01mm

U=Uo-Ue

式中：

U---斜坡流淌值,mm

Uo---初读数,mm

Ue---恒温48h时的读数,mm

★以每组6个试件测值的平均值作为试验结果,若6个试件中有1个

或2个试件的流淌值与平均值之差超过10％,则取其余试件的平均值作为试验结果：如有3个以上试件的流淌值与平均值之差超过15％,应重新试验。

沥青混凝土斜坡流淌值试验仪试验完毕后,清理表面,罩好防尘罩

Test results processing of asphalt concrete slope flow tester:

The slope flow value is calculated according to the formula, ** to 0.01mm

U = Uo-Ue

In the formula:

U --- slope flow value, mm

Uo --- initial reading, mm

Ue --- reading at constant temperature for 48h, mm

Take the average value of 6 test pieces in each group as the test result, if 1 of the 6 test pieces

Or if the difference between the flow value of the 2 test pieces and the average value exceeds 10%, then take the average value of the remaining test pieces as the test result: if the difference between the flow value of 3 or more test pieces and the average value exceeds 15%, the test.

After the asphalt concrete slope flow tester is finished, clean the surface and cover it with a dust cover.
