description	PROBLEM TO BE SOLVED: To provide a freeze-melt testing method for interlocking blocks by which not only resistivity to freezing and melting consistent with the result of exposure testing of interlocking blocks can be evaluated even though no dedicated testing apparatus is used but also water-keeping interlocking blocks, which are difficult to evaluate by any conventional method, can be evaluated.SOLUTION: By a freeze-melt testing method for interlocking blocks, the resistivity of an interlocking block to freezing and melting is evaluated by measuring the rate of mass decrease of the interlocking block sample after performing freezing and melting in a prescribed cycle while part of the interlocking block sample is soaked in water, 10 to 30% of the height of the sample is soaked in water and 100 to 200 cycles of freezing and melting are performed of which one cycle consists of freezing at -17±7°C for 15 to 17 hours and melting at 5°C or above for 7 to 9 hours.SELECTED DRAWING: Figure 1 【課題】本発明は、専用の試験装置を用いなくてもインターロッキングブロックの暴露試験結果と整合する凍結融解抵抗性を短時間で評価できるうえ、従来は評価が困難であった保水性インターロッキングブロックであっても評価可能なインターロッキングブロックの凍結融解試験方法を提供することを目的とする。【解決手段】インターロッキングブロック供試体の一部を水に浸漬しながら、所定サイクルの凍結及び融解を行った後の、当該インターロッキングブロック供試体の質量減少率を測定してインターロッキングブロックの凍結融解抵抗性を評価するインターロッキングブロックの凍結融解試験方法であって、供試体の高さの１０〜３０％まで水に浸漬し、−１７±７℃で１５〜１７時間の凍結と５℃以上で７〜９時間の融解を１サイクルとする凍結及び融解を１００〜２００サイクル行う、ことを特徴とするインターロッキングブロックの凍結融解試験方法、を提供する。【選択図】図１
