摘要
研究了砖-砼混合再生骨料在道路基层中应用的级配优化设计。利用振动压实试验模拟和量化再生骨料的砖组分在应用中再次破碎的情况,从而对级配进行优化处理,使其贴近级配中值,并通过贝雷法验证优化和振动压实后的级配,效果良好。
The gradation optimization design of brick concrete mixed recycled aggregate in roadbase was studied in this paper. Compaction test was used to simulate and quantify the recrushing for brick components of recycled aggregate in application. The gradation was optimized to make it close to the median value of gradation. The optimized and compacted gradation was verified by Bailey method,and the effect was good.
