纤维掺量对纤维微表处路用性能的影响研究

The Study on the Influence of Fiber Content on the Pavement Performance of Fiber Micro-surfacing

在重载交通下,微表处的高温稳定性和抗水损能力较差,为提高微表处的使用寿命常常在微表处中添加少量纤维。对纤维掺量在纤维微表处的湿轮磨耗损失、混合料抗松散性、高温稳定性等路用性能进行试验研究,根据试验结果得出纤维掺量宜控制在0.15%~0.25%。

The high-temperature stability and resistance to water damage of micro-surfacing are worse under heavy traffic. The service life of micro-surfacing is usually improved by adding a small amount of fibers. This paper conducted experimental research on the pavement performances like wet wheel abrasion loss, mixture looseness resistance and high-temperature stability etc. for the fiber content in fiber micro-surfacing. It was concluded from the above test results that the fiber content should be controlled at 0.15%-0.25%.
