多功能馬歇爾擊實儀操作步驟:
①將拌好的瀝青混合料均勻稱取一個試件所需的用量(約1200g/4050g)當(dāng)已知瀝青混合料的密度時，可根據(jù)試件的標準尺寸計算并乘以1.03得到要求的混合料數(shù)量。
②在試件制作過程中，為防止混合料溫度下降，應(yīng)連盤放在烘箱中保溫。從烘箱中取出預(yù)熱的試模及套筒，用沾有少許黃
油的棉紗檫拭套筒，底座及擊實錘底面，將試模裝在底座上，墊一張圓形的吸油性小的紙，按四分法從四個方向用小鏟將混合料鏟人試模中，用插刀或大螺絲刀沿周邊插搗15次，中間10次。插搗后將瀝青混合料表面整平成凸圓弧面。對大型馬歇爾試件，混合料分兩次加入，每次插搗次數(shù)同上。
③插入溫度計，至混合料中附近，檢查混合料溫度。
④待混合料溫度符合要求的壓實溫度后，將試模連同底座一起放在擊實臺上固定，在裝好的混合料上面墊一張吸油性小的圓紙，再將裝有擊實儀錘及導(dǎo)向棒的壓實頭插入試模中，開啟本擊實儀開始實驗。
Multifunctional Marshall compactor operation steps:
① Weigh the mixed asphalt mixture evenly to the amount required for a test piece (about 1200g / 4050g). When the density of the asphalt mixture is known, it can be calculated according to the standard size of the test piece and multiplied by 1.03 to obtain the required mixture. Material quantity.
② During the production of the test piece, in order to prevent the temperature of the mixture from falling, it should be placed in an oven to keep heat. Remove the pre-heated test mold and sleeve from the oven and apply a little yellow
Oil cotton wipes the sleeve, the base and the bottom of the compaction hammer, installs the test mold on the base, pads a piece of circular oil-absorbing paper, and shovels the mixture with a spatula from four directions according to the quarter method In the human test mold, use a knife or a large screwdriver to insert 15 times along the periphery and 10 times in the middle. After plugging, flatten the surface of the asphalt mixture into a convex arc surface. For large Marshall test pieces, the mixture is added in two portions, and the number of times of each plug is the same as above.
③ Insert the thermometer to the vicinity of the mixture and check the temperature of the mixture.
④ After the temperature of the mixture meets the required compaction temperature, place the test mold together with the base on the compaction table and fix it. Place a sheet of oil-absorptive round paper on the assembled mixture and compact it with compaction. The compaction head of the hammer and the guide rod is inserted into the test mold, and the compactor is turned on to start the experiment.
多功能馬歇爾擊實儀實驗過程（接合圖中所示進行操作）<注意>試驗前先接通三相380V電源，并檢查輸入航空插頭，與工作輸出航空插頭是否接牢，然后打開電源<20>。顯示屏顯示“日日"，按照所需錘擊次數(shù),按置數(shù)器<19>設(shè)定好。放下壓模裝置<7>壓緊試筒，然后松開錘座<1>
使導(dǎo)桿落下，用手觸動點動<18>觀察傳動輪，正反轉(zhuǎn)。(注：挑錘塊<4>逆時針行駛為正轉(zhuǎn),反之則更改電源線，任意調(diào)換其中兩根即可，一切正常后，按下“啟動"
<17>，擊實儀開始工作）。當(dāng)試件擊實一面后,取下套筒將試模調(diào)頭,然后以同樣的方式和次數(shù)擊實另一面。
試件擊實結(jié)束后，立即用鑷子取掉上下面的紙，用卡尺量取試件離試模上口的高度，并由此計算試件高度,如不符合要求,試件應(yīng)作廢,并按下式調(diào)整試件的混合料質(zhì)量，以保證高度符合95.3mm±2.5mm/63.5mm±1.3mm的要求.
后卸去試筒及底座，將裝有試件的試模橫向放置冷卻至室溫（不少于12小時）置脫模機上脫出。
Multi-functional Marshall compactor experiment process (operate as shown in the figure below)
Make the guide rod fall, touch the hａnd to jog <18> to observe the transmission wheel, forward and reverse. (Note: Pick the hammer block <4> to run counterclockwise for forward rotation; otherwise, change the power cord and replace any two of them. After everything is normal, press "Start"
<17>, the compactor starts to work). When the test piece is compacted on one side, remove the sleeve and turn the test mold, then compact the other side in the same manner and number of times.
Immediately after the compaction of the test piece, remove the upper and lower paper with tweezers, use a caliper to measure the height of the test piece from the upper mouth of the test mold, and calculate the height of the test piece from this. Adjust the mix quality of the test piece according to the following type to ensure that the height meets the requirements of 95.3mm ± 2.5mm / 63.5mm ± 1.3mm.
After removing the test cylinder and the base, place the test mold containing the test piece in a horizontal position and cool it down to room temperature (not less than 12 hours) on a mold release machine.
多功能馬歇爾擊實儀工作完畢后，把試模清理干凈以備下次實驗用。把本儀器擦拭干凈，并在導(dǎo)桿擊實錘傳動輪上拭上潤滑油。把配電箱上電源斷開，電源開關(guān)關(guān)閉。
After the multifunctional Marshall compactor is finished, clean up the test model for the next experiment. Wipe the instrument clean and lubricate it on the guide hammer driving wheel. Disconnect the power from the distribution box and turn off the power switch.
多功能馬歇爾擊實儀常見故障與排除：
1、工作當(dāng)中出現(xiàn)不提錘現(xiàn)象或在提錘過程中脫錘。檢查傳動鏈條是否松動，如松動可調(diào)節(jié)后面調(diào)整羅栓，擊實錘上彈片是否受損，需要更換，挑錘塊與放錘鍵是否磨損太重。
2、顯示屏上數(shù)字顯示異?；虿挥嫈?shù)。檢查上傳動輪處接近開關(guān)，是否松動或接近距離太遠。
3、在打開電源開關(guān)后整個顯示屏不顯示。檢查電源是否正常或配電箱后保險管是否熔斷。
4、在提錘過程中，連同導(dǎo)向桿一并提起脫不開。鏈條是否太松，導(dǎo)向桿上是否缺少潤滑油或污垢太多
Common faults and troubleshooting of multifunctional Marshall compactor:
1. Do not lift the hammer during work or release the hammer during the lifting process. Check whether the transmission chain is loose. If it is loose, you can adjust the adjustment bolts on the back. If the shrapnel on the hammer is damaged, it needs to be replaced. If the pick block and put key are worn too much.
2. The digital display on the display screen is abnormal or not counting. Check if the proximity switch at the upper drive wheel is loose or too close.
3. After the power switch is turned on, the entire display is not displayed. Check whether the power supply is normal or the fuse is blown after the power distribution box.
4. In the process of lifting the hammer, it cannot be lifted together with the guide rod. Is the chain too loose, is there a lack of lubricant or too much dirt on the guide bar
