贫混凝土混合料的特点在于水泥含量低和使用浇灌质量好的洗净集料。含水量的选择应尽可能地降低混合料的和易性以适合滚压要求。材料是用自卸汽车并复盖起来运送的,基层摊铺不留伸缩缝,这样可以快速施工。7天养护期后,能承受施工期交通。 Lean concrete mixes are characterized by a low level of cement and the use of well-watered wash aggregates. The choice of water content should be as low as possible to reduce the mixture of workability to meet the rolling requirements. The material is dumped and covered by the transport, the basic pavement without leaving expansion joints, so you can quickly construction. After 7 days curing period, can bear the traffic during construction.
