Jiao Shengjie

Jiao Shengjie did it《Asphalt Mixture Mixing Technology and Its Development Prospect》 The report of。The report is based on the development background of asphalt mixing technology.、Literature、Patents and other major research directions are analyzed.。He pointed out,At present, there are about 1..40,000 sets of asphalt mixture mixing equipment of different types,Among,95%All of the above are intermittent.,Time of use 1~About 32% in 5 years%,6~About 47% in 10 years%,About 21% for 11 years and above%,The production scale and quantity of mixing equipment rank first in the world.,The technical level is equivalent to that of foreign brands.。And“Fourteen five”In the planning, a clear goal is put forward for the utilization of old asphalt materials.:Recycling rate of asphalt pavement materials for expressways 95%,General National and Provincial Highway 80%。Some economically developed cities require expressways 100%,General Provincial Highway 95%Above。The task of efficient resource utilization of bulk waste asphalt mixture is very arduous.,This also provides an opportunity for the development and application of new equipment.。And from the present vibration、From the form of shaking and stirring,The utilization rate of patent conversion is still low。

Li Taijie

Li Taijie did it《Research on Asphalt Mixture Oscillating Mixing Technology》The report of。The report States,Vibration mixing technology is based on the traditional mixing.,Add 1 low amplitude to the mixing blade、High frequency fluctuation,Thereby improving the mixing quality.。At present, there are mainly shaft end rotation methods.、Shaft end translation method、Free vibration method and two-axis pendulum array method。The vibration of the whole machine is serious and the transmission parts are easy to be damaged in the vibration mixing, especially in the rotary shaft end.,The reason is that the rotation of the mixing shaft leaves the center.,Cause high frequency displacement of that mass cent of the stirring system,At the same time, the transmission parts are easy to be damaged.。So,Drawing lessons from the principle of oscillating structure of oscillating roller,It is found that it can completely meet the needs of shaking and stirring.,And that stir axis does not deviate from the central position in the oscillation proces.。

Issued by Xi'an Changda Highway Engineering Inspection Center《Performance Test Report of Oscillating Mixing Asphalt Mixture》As can be seen in,SMA-13 Freeze-thaw splitting test results of fine-grained asphalt concrete from water stability、Several key performance indexes of low temperature crack resistance meet the requirements of specifications.。
