　　浇筑式沥青混凝土具有较高的变形随从性而在钢桥面铺装上得到了很多的应用，为研究浇筑式沥青混凝土的性能影响因素，采用4种合成级配、3种沥青用量，系统评价了各因素对浇筑式沥青混凝土性能的影响。通过流动度试验和贯入度试验确定最佳含油量，由高温车辙试验和低温弯曲试验进行路用性能检验。研究表明，级配形式和沥青含油量变化对混合料的性能指标的影响较大，因此，实际施工时应严格控制混合料的级配和沥青用量。

Gussasphalt concrete has been widely used in steel bridge deck pavement because of its high deformation. In this paper,Factors impacted on Gussasphalt mixture performance are systematic studied by four type gradation,three asphalt content. The best asphalt content was determined by fluidity tests and penetration tests. The road performance was verified by high temperature rutting test and low temperature bending test. The study shows that gradation and asphalt content have a great influence on the performance of mixture. Therefore, the gradation and asphalt content should be strictly controlled in the actual construction.
