工程渣土再生填料长期浸水性能试验研究

Experimental Research on Long-term Water Immersion Performance of Engineering Waste Soil Recycled Filler

工程渣土再生填料浸水条件下的性能衰减是一个复杂过程,分析掌握其衰减规律具有重要意义。通过浸水试验,研究了工程渣土再生填料试件在室内静荷载作用下,浸水时长7~360d范围内的抗压强度和质量变化。试验数据表明,浸水条件下,工程渣土再生填料保持了前期强度增长较快、后期平缓的增长趋势,同时试件完整性较好。综合来看,在长时间浸水条件下,工程渣土再生填料可保持良好的路用性能,符合沿海地区道路工程使用要求。

The performance degradation of the engineering waste soil recycled filler under the condition of water immersion is a complex process,and the analysis and mastery of its degradation law is of great significance.Through the water immersion test,the compressive strength and quality changes of the test specimen of the engineering waste soil recycled filler under the indoor static load are studied within the range of 7-360d of water immersion time.The test data shows that,under the condition of water immersion,the engineering waste soil recycled filler maintains a rapid increase in strength in the early stage and a gentle growth trend in the later stage.Meanwhile,the integrity of the test specimen is good.Overall,under the condition of long-term water immersion,the engineering waste soil recycled filler can maintain good road performance and meet the operating requirements of road engineering in coastal area.
