METHOD FOR DETERMINING GRANULAR MATERIAL, MANUFACTURING METHOD OF GRANULAR MATERIAL FOR ROADBED MATERIAL AND MANUFACTURING METHOD OF ROADBED MATERIAL
To provide a method for determining granular material which makes it possible to easily determine whether the corrected CBR required for the roadbed material is satisfied or not.SOLUTION: There is provided a method for determining granular material which determines whether the corrected CBR required for the roadbed material is satisfied or not, the method grasping in advance a correlation formula and a standard deviation of the content percentage of a predetermined particle size having correlation relation with a corrected CBR value and said corrected CBR; calculating the estimated value of the corrected CBR of the granular material using the correlation formula with the standard deviation of 45% or less; determining that the granular material is the granular material satisfying the corrected CBR when the estimated value exceeds the reference value of the corrected CBR required for the roadbed material; and determining that the granular material is the granular material not satisfying the corrected CBR when the estimated value is below the reference value of the corrected CBR required for the roadbed material.SELECTED DRAWING: Figure 1
【課題】路盤材に求められる修正ＣＢＲを満足するか否かを容易に判断できる粒状材の判断方法を提供する。【解決手段】粒状材が修正ＣＢＲを満足するか否かを判断する粒状材の判断方法であって、修正ＣＢＲ値と相関関係を有する所定粒度の含有率と前記修正ＣＢＲとの相関式と標準偏差を予め把握しておき、標準偏差が４５％以下である相関式を用いて粒状材の修正ＣＢＲの予測値を算出し、予測値が路盤材に要求される修正ＣＢＲの基準値以上である場合に、粒状材は修正ＣＢＲを満足する粒状材であると判断し、予測値が前記修正ＣＢＲの基準値未満である場合に、粒状材は修正ＣＢＲを満足しない粒状材であると判断する。【選択図】図１
