摘要
本文在纤维土材料收缩性能研究课题的基础上,参考国内外收缩性能试验方法,着重探讨了纤维加固路面基层半刚性材料的温度收缩和干燥收缩的试验方法,并且对试件制备、测试技术关键及仪器设备的选用进行了分析和说明。为定量地研究沥青路面基层材料与纤维土材料的收缩性能指标和抗裂设计数据采集提供了一种较可靠的测试方法。
Based on a question for study in collaboration with shrinkage property of fibrousreinforcement soil materials, consulted test method of shrinkage property at home andabroad, the test method of temperature and dry shrinkage of fibre reinforced semi-rigidbase course materials is discussed emphatically in this paper. The preparation of sampleand the crux of test technigue are analysed, the selection of instruments and facilities isillustrated. A new test method for researching shrinkage property indices of base coursematerials of bituminous pavement and fibrous reinforcement soil materials quantilativelyand collecting date of crack-resisting design is provided.
