摘要
纤维的掺入能有效改善沥青混凝土的性能。目前路用纤维种类众多,以AC—13为依托,选用了木质素纤维、矿物纤维、改性纤维和复合改性纤维等四种常用的道路纤维进行了高温抗车辙试验和低温抗裂试验,用以评价不同纤维对沥青混凝土路用性能的影响。研究表明,纤维的加入对沥青混凝土的高低温性能均有较好的改善,但是不同纤维的效果还是有一定区别的。
The doping of fibre can improve the performance of asphalt concrete.There are great varieties of road fibre at present.Taking AC-13 as example,four common road fibre such as lignin fibre,mineral fibre,modified fibre and composite modified fibre are selected to implement high-temperature rut test and low-temperature crack resistance test in order to evaluate the influence of different fibre on asphalt concrete pavement′s performance.The research indicates that the doping of fibre can improve the performance of asphalt concrete either in high temperature,or in low temperature,but the effect of various fibre are different.
