Problems solved by technology

[0002] The current JJG (Traffic) 065-2006 "Asphalt Mixture Marshall Compaction Instrument Verification Regulations" is the verification standard for asphalt mixture Marshall compaction instrument. During the test, the compaction hammer moves up and down, and the compaction hammer falls. friction between the center and the guide rod, and the contact between the compaction hammer and the compaction surface of the test piece cannot be guaranteed, so it is difficult to ensure that the test piece can obtain sufficient compaction effect. It is not enough to evaluate the forming effect of the test piece by parameters such as the quality of the hammer.

Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0032] like figure 1 and figure 2 As shown, a metering device of Marshall compaction meter for asphalt mixture is used to quantitatively measure the effect of hammer 7 of Marshall compaction meter 1 of asphalt mixture on the forming of test pieces. In order to clearly show the metering device of Marshall compaction meter for asphalt The specific implementation manner of the asphalt mixture Marshall compaction instrument 1 is described here. The asphalt mixture Marshall compaction instrument 1 includes a wooden pier 2, a compaction head 5, a guide rod 6, and a compactor set on the guide rod 6. Hammer 7, the limit block 8 that is located at guide bar 6 tops, compaction head 5 and guide bar 6 are integral structures, and when testing, asphalt mixture sample is put between wooden pier 2 and compaction...

Abstract

The invention discloses a metering device and a metering method for a marshall compaction testing apparatus for an asphalt mixture, relating to the field of metering devices. The metering device for the marshall compaction testing apparatus for the asphalt mixture comprises a base located on a timber pier of the marshall compaction testing apparatus, a force sensor arranged on the base, an elastic cushion located on the force sensor, a sleeve, a support, a signal acquisition device and a PC, wherein the base, the force sensor and the elastic cushion are all fixed in the sleeve, a first distance measurement sensor and a second distance measurement sensor are arranged on the support, the signal acquisition device is connected with the force sensor, the first distance measurement sensor and the second distance measurement sensor and the PC is in communication connection with the signal acquisition device. The invention also discloses the metering method of the metering device. The metering device and the metering method can solve the problems that the lifting height of a hammer under a dynamic condition cannot be measured accurately and the metrological verification items in existing verification regulation are incomplete.

Description

technical field [0001] The invention relates to the field of metering devices, in particular to an asphalt mixture Marshall compaction meter metering device and a metering method thereof. Background technique [0002] The current JJG (Traffic) 065-2006 "Asphalt Mixture Marshall Compaction Instrument Verification Regulations" is the verification standard for the asphalt mixture Marshall compaction instrument. During the test process, the compaction hammer moves up and down, and the compaction hammer falls. friction between the center and the guide rod, and the contact between the compaction hammer and the compaction surface of the test piece cannot be guaranteed, so it is difficult to ensure that the test piece can obtain sufficient compaction effect, the maximum lifting height of the compaction hammer, compaction It is not enough to evaluate the effect of the test piece forming by parameters such as the quality of the hammer. Contents of the invention [0003] An object o...
