Product Name: Carrying Ratio Tester

Carrying ratio analyzer

Carrying ratio meter price

The load ratio is based on the analyzer

JTJ059-95

Designed and manufactured according to the "On-Site Test Procedure for Highway Subgrade Pavement", applicable to the site of measuring various soil-based materials on the road site.

CBR

value.

The working principle is to use the rear bearing weight not less than

60KN

The truck is loaded with a jack, and the amount of penetration measured by the penetration rod and the weight of the load measured by the dynamometer are calculated.

Carrying ratio analyzer

experiment method:

1.

Digital display bearing ratio analyzer based on design

Seek soil compaction test and determine the optimum water content of the test soil

(OMC)

And maximum dry density

(rdmax)

.

2.

The digital display bearing ratio analyzer adjusts the soil sample according to the optimal water content of the obtained soil.

And divide the soil into three layers

(

Five floors

)

Each layer

10

under,

30

under,

65

The number of snips under, the soil sample into the lower pad

CBR

In the mold, three sets of different tamping energy samples were tested.

3.

The digital display load ratio analyzer removes the mold extension ring,

After smoothing the surface of the test piece, the test piece is turned over and the bottom block of the mold is removed.

4.

The digital display carrier is fixed on the bottom of the test piece after the meter is turned over.

After the overloaded base is installed, it is mounted on the anti-pressure main body, and the surface of the test piece is slightly contacted with the penetration rod on the anti-pressing machine by manual control.

5.

Start the pressure press to

1.27mm/min

The rate causes the penetration rod to be pressed into the test piece.

f.

Using the measurement system to read the penetration of the penetration rod and its corresponding penetration impedance, until the penetration impedance drops or the penetration amount reaches

12.7mm

Up to the above.

6.

The soil samples were ejected from the mold, and the soil samples were taken in the upper, middle and lower parts, respectively.

7.

repeat

2~3

After the filter paper is added to the upper and lower sides of the test body, the test body is fixed on the porous bottom sill, and after adding the expansion extender, the overload base raft, the expansion frame and the micrometer, all the equipment is placed in the water tank, and water is added to make the water Flooded the top of the test body while recording the amount of soil expansion

96

The hour or amount of expansion no longer increases.

8.

Take the test body out of the water tank, pour off the upper part of the water and let it rest.

15

Minutes allow it to drain freely.

9.

The test body is mounted on the anti-pressure main body, and the surface of the test piece is slightly contacted with the penetration rod on the anti-pressure machine by manual control, and then repeated

5~7

step.
