Abstract
The necessity of the antifreezing admixture increases more and more in road surface management in the winter period, since spike tire is forbidden in 1989. The development of the effective measures is desired a grasp of the antifreezing admixture residual concentration at present, since it is connected the cost reduction environmental loading spraying quantity. Then, in this study, fluorescence X-ray which could quantitatively measure nondestruction, noncontacting element was noticed, and it did the verification of the possibility of residual concentration measurements of the antifreezing admixture with the purpose. By assay result got by the X-ray fluorescence analyzer, it was possible to grasp the relationship between X-ray intensity of Cl and area ratio of antifreezing admixture.
