未添加任何穩定劑的壓實泥岩碎屑由於力學性質及體積穩定性不佳，並非良好的填方材料。泥岩碎屑經石灰穩定處理後可大幅提高其強度、承載力，同時可有效降低泥岩的回脹性、壓縮性及對水的敏感性，添加3%～6%石灰可有效改良泥岩碎屑的工程性質，適合作為路基材料之用。然而，額外添加卜作嵐材料，對於泥岩碎屑的穩定成效並無明顯的助益。

The compacted mudstone fragment, without adding any stabilizer is not suitable for fill material, because it does not possess good mechanical properties and volumetric stability. Mudstone fragment stabilized with lime has many beneficial effects: An increase in strength, an increase in bearing capacity, a reduction of swelling, a reduction of compressibility and a reduction of the moisture-sensitivity. Adding 3%~6% lime to mudstone is the economic and reasonable one to improve engineering properties and suitable for the subgrade materials. From the point of view of soil stabilization it is not necessary to add excess pozzolanic material for mudstone fragment.
