A high performance level Macadam and preparation method

The present invention relates to a high performance level Macadam, the percentage by weight of component consists of the following components: graded gravel: 93.5-95.95%; road fiber: 0.05-0.15%; drinking water: 4.0-5.0% . High-performance graded gravel to claim 1, wherein a material prepared by mixing method comprises the following steps: the aggregate used in accordance with the full mesh from 0.075mm ~ 31.5mm stepwise screening, from the large to the aggregate little material is divided into single file, as shown in table 1 using having intermediate range with graded gravel: the above graded gravel stir; manual or mechanical input path fiber; vibration compaction method was used to determine the level of Macadam optimum moisture content and maximum dry density; join the optimum moisture content of water, stir, to obtain level Macadam finished. High-performance graded gravel of the present invention significantly improve the mix temperature graded gravel flexible pavement rutting capacity, reduce heavy vehicles and Heavy Traffic Load on Asphalt Pavement damage, effectively extending the service life of asphalt pavement.
