The need for research of Multiple-Head Crusher

March 29, 2011 - PRLog -- With the increasing of traffic, especially the increasing of hcavy-duty vehicle, the cement  concrete pavement has appeared some destructions such as: faulting of slab ends, crack slab,pumping, and so on in the past few years. The service capability and the structure capability  of cement concrete pavement are affected by these destructions. Minor repair and small mend already has no way to satisfy the need of road traffic capacity. The asphalt cover course,which is rebuilt by traditional method, will generate reflecting cracks in one or two years  which will accelerate the destruction of aspbalt cover course. Reflecting cracks have restricted the development and rehabilitating of cement concrete pavement. How to control the reflecting cracks effectively is the key subjects being confronted with the reconstruction of
cement concrete pavement, which is also the main motivation ofthis paper.
     The technicmeans coping with this problem is limited due to the backward machanical manufacture in our country. In respect to the treatment of old concrete pavement, America has accumulated a set of technology called rubblization technology. This paper has done the following studies on the Multiple-Head Crusher rubblization technology:
       1. The broken mechanism of Cement concrete pavement and the intensity principle of rubblized slab.
      2. One grid model ofcement concrete pavement is established, which is ansysed by the software ANSYS. The Natural frequency and "height of drop hammer - stress" curve is worked out by the ansys result.
       3 . Explored the construction process ofrubblization technology
