瀝青混凝土斜坡流淌值試驗儀儀器的組成：

★鋼板制成：主機1臺,可放置6個試件。

★萬用電表1個。

★位移計：精度0.01mm6個。

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.

瀝青混凝土斜坡流淌值試驗儀試驗步驟：

★按規(guī)定制備瀝青混合料,按規(guī)定成型馬歇爾試件,每組6個,高度63.5mm±1.3mm。從現(xiàn)場鉆取的芯樣,應加工成直徑為100mm±3mm,高度為63.5mm±1.3mm的試件。

★試件成型后,在室溫條件下放置24h,測量試件高度。

★采用耐高溫的高強度黏結(jié)劑將每個試件粘貼的斜坡流淌儀上,在距試件底部50mm處用高強度黏結(jié)劑粘貼8mm×3mm×1mm的銅片,在銅片的一根導線,在流淌儀板面上有一根公用導線：各銅片的導線及公用導線分別與萬用表兩連接,調(diào)整位移計位置,使位移計測頭與銅片接觸,檢驗電路是否接通。位移計距離斜坡面垂直距離50mm。

★將斜坡坡度調(diào)整至設(shè)計規(guī)定的坡度,如無規(guī)定,斜坡坡度科采用1:1.7。

★將烘箱升至試驗溫度,溫度誤差控制在±1℃。試驗溫度可按工程實際情況確定,如無規(guī)定,可采用70℃。

★斜坡流淌儀放入烘箱前,調(diào)整位移計,讀取各試件的初讀數(shù)Uo,然后將斜坡流淌儀平穩(wěn)放入已升溫至試驗溫度的烘箱內(nèi)。

★恒溫48h,讀取各試件的變形值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.

瀝青混凝土斜坡流淌值試驗儀試驗結(jié)果處理：

★斜坡流淌值按式計算至0.01mm

U=Uo-Ue

式中：

U---斜坡流淌值,mm

Uo---初讀數(shù),mm

Ue---恒溫48h時的讀數(shù),mm

★以每組6個試件測值的平均值作為試驗結(jié)果,若6個試件中有1個

或2個試件的流淌值與平均值之差超過10％,則取其余試件的平均值作為試驗結(jié)果：如有3個以上試件的流淌值與平均值之差超過15％,應重新試驗。

瀝青混凝土斜坡流淌值試驗儀試驗完畢后,清理表面,罩好防塵罩

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.
