Adding the fiber into the concrete pavement can help the plastic shrinkage or expansion of the Asphalt Concrete and the tension when it is freeze-thawing, it can increase street’s toughness significantly, and inhibit the emergence and development of crack and play drum, make the cracking capacity getting a full progress, in the same time increase the intensity of the asphalt concrete, extend the using life, increase maintenance costs. In order to produce fiber, now many road constructions are artificial-breaking the massive fiber-board, so it is need a kind of crushing equipment to process suitable fiber. This is the base of the papers. The main contents are as follows: 1. Design the basic tenet and structure of the fiberboard. 2. Design the external body. 3. In the base of calculation and experiment, design the main components in fiber board crushing equipment. 4. Using CAXA software draws the assemble chart 5. Check Designed components’ accuracy and assembling reasonable, address the problem and then give the proper improvement program.
