研究发现,雷达法对于水泥混凝土路面中的传力杆布置环境及混凝土保护层厚度有较好的适用性,可以作为今后水泥混凝土路面传力杆保护层厚度测量的主要方法,同时发现水泥混凝土龄期达到28d以后,深度校准值基本维持在一个定值,在不改变水泥混凝土配合比和养护条件的前提下,可以考虑使用定值参数在水泥混凝土龄期达到28d强度后再进行钢筋保护层厚度的测量。 It is found that the radar method has good applicability to dowel bar arrangement environment and concrete cover thickness in cement concrete pavement and can be used as the main method for measuring the thickness of dowel bar protective layer in cement concrete pavement. In the meantime, After the period reaches 28d, the depth calibration value is basically maintained at a fixed value. Without changing the mix ratio and curing conditions of cement concrete, it may be considered to use the set value parameters to make the thickness of reinforcement protection layer after the cement concrete age reaches 28d Measurement.
