在广东省某高速公路上的一些试验段采取了三种雾封层措施以及微表处理和NovaChip~两种罩面措施,根据2004年和2006年两次FWD检测结果,采用t检验、秩和检验、方差分析和多重比较的方法对弯沉衰减数据进行了分析。结果表明,对于延缓路面结构强度衰减而言,三种雾封层措施和微表处理措施效果明显,而NovaChip~的效果较弱;相对于CAP、HAP和微表处理,沥再生的效果较弱,而前三者的效果之间并无明显差别;上述的数据分析方法适用于预防性养护措施的效果评价。
In some test sections on a highway in Guangdong Province, three kinds of fog sealing measures, as well as micro-surfacing and NovaChip ~ 罩 two overlay measures were adopted. According to the results of two FWD tests in 2004 and 2006, And the test, analysis of variance and multiple comparison method of bending attenuation data were analyzed. The results show that, for the delay of strength attenuation of pavement structure, the three kinds of fog seal measures and microdialysis measures are effective, while the effects of NovaChip ~ are weaker; Compared with CAP, HAP and micro-surface treatment, Weak, while there is no significant difference between the effects of the former three. The above data analysis method is applicable to the evaluation of the effect of preventive maintenance measures.
