Resonant Crushing and Screening Technology

The Resonant Crushing Technology, utilizing the resonance principle, causes the old cement concrete pavement to resonate with the resonant crusher,破碎成a layer of crushed cement concrete aggregate with the upper layer interlocking and the lower layer interlocking. The crushed stones have complementary shapes, smaller particle sizes, and form a stable interlocking structure, addressing the horizontal and vertical displacements in the cracks and joints of the original cement concrete pavement. It eliminates the stress that reflects upwards from the cracks in the original slabs, and the strength and stiffness of this layer are higher than those of graded crushed stone. Additionally, it has a lesser impact on the subgrade of the old road, making it an effective method for resolving the issue of reflective cracks that often occur when resurfacing cement concrete pavements.
