| 摘 要： | 采用粗细不同2种级配进行水泥稳定砂砾混合料的室内外强度试验,以验证砂砾材料用于骨架密实水稳混合料时,细集料用量对强度的影响程度.结果表明,细集料减少,砂砾与水泥粘结力下降,建议级配设计时应综合考虑砂砾材料嵌挤力对混合料强度的影响.

| Abstract: | This paper conducted indoor and outdoor strength test on cement-stabilized gravel mixture with two different kinds of thickness to verify the influence of fine aggregate dosage on strength of skeleton density type cement-stabilized mixture by using gravel material. The resuhs showed bond force between gravel and cement declined, when dosage of fine aggregate decreased. It was suggested that the influence of interaction between gravel on mixture strength should be considered during gradation design. |
