摘要:
为了研究不同级配对紫外光老化沥青混合料高低温性能的影响,分别选取AC-13和AC-16各5种S型级配进行室内试验,
分析不同级配对紫外光老化沥青混合料高低温性能的影响规律.试验结果表明:各级配沥青混合料的动稳定度及低温劈裂强
度在紫外光老化后都呈降低的趋势,但级配不同其降低幅度有所不同;在S型级配矿料组成中,粗集料含量越多,紫外光老
化后沥青混合料的动稳定度下降越少.细集料含量越多,紫外光老化后沥青混合料的低温劈裂强度下降越少.其中AC-13S5
型、AC-16S4型级配具有较好的高温抗紫外光老化性能,AC-13S1型、AC-16S2型级配具有较好的低温抗紫外光老化性能.
Abstract:
In order to investigate the effect of different gradation on the temperature performance of UV aging asphalt mixture,
AC-13 and AC-16 were selected for each of 5 graded indoor tests, in analyzing the different gradation of UV aging asphalt Mixture
influence of temperature performance. The results show that Levels with asphalt mixture dynamic stability and low cleavage strength
after UV aging were tested to show a decreasing trend, but with a different level of its reduction ranges. The S-type composition
graded mineral aggregate, coarse aggregate content more dynamic stability after UV aging asphalt presents a smaller decline. the
more material content of fine aggregate, the less after UV aging asphalt splitting strength at low temperature. Where AC-13S5 type,
AC-16S4 type gradation has good high temperature anti-aging properties of ultraviolet light, AC-13S1 type, AC -16S2 type gradation
has good low-temperature UV anti-aging properties.
