特种玄武岩纤维增强OGFC-13混合料配合比设计及路用性能试验
Experiments of mix design and pavement performance for special basalt fiber reinforced asphalt mixture OGFC-13
摘要
Abstract
In order to improve the stability and deformation resistance capacity of permeable open-graded friction course(OGFC)asphalt mixture,a kind of flocculent special basalt fiber with good performance is used as a reinforced stabilizer.By selecting different mixing a-mounts of the basalt fiber,the mixture ratios of OGFC-13 were designed,then various pavement performances of the OGFC-13 mixtures under the optimum asphalt aggregate ratios were tested.The results show that the special basalt fiber can adsorb asphalt very well to bond the coarse aggregate skeleton into a firm whole,then all the pavement per-formances of basalt fiber reinforced OGFC-13 including high temperature,low tempera-ture and water stability etc.are obviously improved.However,when the mixing amount of basalt fiber is too high,a part of basalt fiber reinforced asphalt mortar distributes in the connected voids of OGFC-13 to cause the reduction of void ratio,and a few basalt fiber with uneven dispersion is easy to form the weak points in the mixture structure,influencing the mixture pavement performances.Therefore,the suitable range of mixing amount of the special basalt fiber is determined as 0.3%~0.5%,and the optimum mixing amount is 0.4%.The results could provide references for the engineering application of permeable as-phalt pavement with noise reduction.关键词
