摘要
结合工程所在地气候、交通状况及工程材料特点,设计了薄层罩面用温拌纤维沥青混合料级配;通过对比试验研究了级配、矿物纤维种类与掺量、温拌剂掺量及沥青混合料成型温度对薄层罩面用混合料性能的影响规律并就降低温度后的沥青混合料对施工工艺的影响进行了分析;提出了应用温拌纤维沥青混合料解决薄层罩面施工中热量易于散失,温降过快,难于压实等实际工程问题的方法.对于提高薄层罩面质量,延长道路使用寿命具有重大的工程指导作用.
Based on the local climate characteristics, traffic conditions and engineering material characteristics, the influ-ence of the grading, the type and the dosage of the mineral fiber, warm mixing agent and forming temperature on the mixture per-formance used in the thin overlay is studied. The construction technology of the asphalt mixture in low temperature is ana-lyzed.The method solving the practical engineering problems arising from thin overlay such as heat loss easily, temperature decrease excessively fast and compaction difficultly is put forward by applying the warm mix asphalt fiber mixture, which provides an impor-tant engineering guidance for improving the quality of the thin overlay and prolonging the service life of the road.
