Pavement deflection instrument technical parameters:

★ leverage ratio: 2:1;

★ fulcrum to the front measuring point length: 3600mm.

★Stiffness: With the center of the shaft hole as the fulcrum, 200g is loaded at 1200mm from the pivot point, and its deflection is not more than 0.05mm.


路面彎沉儀測定方法:

★將儀器杠桿前后連接成一體,按要求檢查好。

★載重汽車一輛,后橋單軸需按規(guī)定標(biāo)定,用以路面加載,氣胎壓力也按規(guī)定調(diào)好。

★熱電阻測計一支~精度℃,用以測定路面溫度(因彎沉值隨溫度變化)。

★指揮交通用的紅旗三面,小鐵棒三根700~300mm,直徑20

Pavement deflection test method:

★Connect the instrument levers back and forth into one, and check them as required.

★ One truck, the rear axle single shaft should be calibrated according to the regulations, used for road loading, and the pneumatic tire pressure is adjusted according to the regulations.

★ Thermal resistance metering one ~ accuracy °C, used to determine the road surface temperature (due to the deflection value with temperature).

★ Three sides of the red flag for traffic control, three small iron bars 700~300mm, diameter 20


路面彎沉儀準(zhǔn)備工作:

★檢查并保持測定用標(biāo)準(zhǔn)車的車況及剎車性能良好,輪胎內(nèi)胎符合規(guī)定充氣壓力。

★向汽車車槽中裝載(鐵塊或集料),并用地中衡測量后軸總質(zhì)量,符合要求的軸重規(guī)定,汽車行駛及測定過程中,軸重不得變化。

★用新的復(fù)寫紙測定輪胎接地面積。

★檢查彎沉儀百分表測量靈敏情況。

Pavement Deflection Instrument Preparation:

★Check and maintain the condition and braking performance of the standard car for measurement. The inner tube of the tire meets the specified inflation pressure.

★ Load (iron block or aggregate) into the car slot, and measure the total mass of the rear axle with the ground balance, meet the required axle weight regulations, and the axle load must not change during the driving and measuring process.

★ Use the new carbon paper to measure the tire grounding area.

★ Check the sensitivity of the deflection meter to measure the sensitivity.


路面彎沉儀操作規(guī)程:

★將儀器擦凈。

★測定選好后,將測定的汽車后軸雙輪間隙中距測點不超過10厘米處。

★將百分表裝在百分表之架上,然后彎沉儀移至路面上,使其測端恰好在雙輪胎間隙的中處(垂直于車軸中點),并調(diào)水平,用表夾及百分表支架的調(diào)平螺絲將百分表讀數(shù)調(diào)至5毫米左右,使指針指零,表的觸頭抵住測點螺釘中,并記錄其讀數(shù)B1.

★汽車向前開動,使其后輪在影響半徑以外,一般距測定5米左右,此時百分表走動,待百分表讀數(shù)穩(wěn)定后(每分鐘變得小于0.01mm),記錄讀數(shù)C1。

★用熱敏點溫計測出并記錄下路面的溫度t。

★將測定結(jié)果,記錄于下式中。

★根據(jù)記錄下的讀數(shù),計算路面彈性彎沉值[1]

Pavement deflection instrument operating procedures:

★ Wipe the instrument clean.

★ After the measurement is selected, the center distance of the two-wheel gap of the rear axle of the car to be measured shall not exceed 10 cm.

★ Put the dial indicator on the frame of the dial indicator, then move the deflection meter to the road surface, so that the measuring end is just at the center of the double tire gap (perpendicular to the center point of the axle), and adjust the level, using the table clamp and The leveling screw of the dial indicator bracket adjusts the dial gauge reading to about 5 mm, so that the pointer points to zero, the contact of the watch against the center of the measuring point screw, and record its reading B1.

★ The car will move forward, so that the rear wheel is outside the influence radius, generally about 5 meters away. At this time, the dial indicator moves. After the dial gauge reading is stable (less than 0.01 mm per minute), the reading C1 is recorded.

★ Measure and record the temperature t of the road surface with a thermal thermometer.

★ Record the results and record them in the following formula.

★ Calculate the deflection of the road surface based on the recorded readings [1]


路面彎沉儀主要結(jié)構(gòu):

主要由前杠桿,后杠桿、底座,百分表、支架等主要部分組成。使用前杠桿、后杠桿用四只M12螺栓連接,不用時將螺栓卸下,前后杠桿分開裝入箱內(nèi)。后杠桿與支架座相連,杠桿與底座之間采用向心球軸承連接,克服了以住采用散彈子軸承結(jié)構(gòu)不穩(wěn)定、靈活性差等缺點,并加有防塵蓋,防止了灰塵和雨水的浸入,加有足夠的潤滑油脂,底座上裝有調(diào)平螺絲和水平裝置,調(diào)整方便。百分表支架上有一表夾,可根據(jù)測量時的高度進行調(diào)整,每臺儀器上配0--10毫米一級精度百分表一只。

The main structure of the pavement deflection instrument:

Mainly composed of front lever, rear lever, base, dial indicator, bracket and other major parts. Use the front lever and rear lever to connect with four M12 bolts. When not in use, remove the bolts and insert the front and rear levers into the box separately. The rear lever is connected with the bracket seat, and the centripetal ball bearing is connected between the lever and the base, which overcomes the disadvantages of unstable structure and poor flexibility of the ball bearing bearing, and is provided with a dust cover to prevent dust and rain from entering. , with enough grease, the base is equipped with leveling screws and horizontal device, easy to adjust. There is a clip on the dial indicator, which can be adjusted according to the height of the measurement. Each instrument is equipped with a 0--10 mm first-class accuracy dial.
