In order to guarantee the porosity and compactness of the road surface, the preparing method of the cold-laid asphalt is much different from the hot-laid asphalt mixture in aspects of the viscosity and consumption of the asphalt, additives, and graded aggregate mixtures, etc.
为保证其疏松性和压实性,在配制方法上,如所用沥青的黏度、沥青的用量、添加剂以及集料级配等,与热拌沥青混合料有很大区别。
The compactibility variation and the strength variation of ISS strengthening soil were analyzed by the results of compaction test and unconfined compressive strength test with different proportions and enclosing material time periods.

Results indicate that the maximum density line (MDL) and the Superpave control points (CPs) can be used as the important parameters to learn the structure, the compactability, and the permanent deformation potential of mixtures.
选取10种级配,以混合料的结构密实性、浸水车辙稳定性和压实性能为基础,提出了在高温多雨地区,满足表面层混合料结构和性能要求的连续密级配的选择方法,研究表明:最大密实线和Superpave控制点可作为了解混合料结构、压实性和永久变形特性的参数依据;在最大密实线和控制点下限之间选取连续密级配,可使混合料兼具良好的结构密实性、浸水车辙稳定性和压实性能,混合料也因此更适用于环境因素复杂的高温多雨地区。

The conclusion is given by analyzing the result and compaction characteristics,which says that each compaction is associated with one maximum dry density.
通过对击实试验结果以及压实特性的分析得出:每个击实功都对应一个最大干密度,且随着击实功的增加,最佳含水量减少,最大干密度增大以及其他相关结论。
This paper firstly gives an introduction of the complete compaction curve and its equation-the latest research results at present about the compaction property for fine-grained soils,and analysises the influence of the equation parameters on the shape of compaction curve,then identifies the accuracy of the equation.
首先介绍了当前有关细粒土压实特性研究的最新成果—全压实曲线及方程,分析了方程参数对压实曲线形状的影响,并对方程式的正确性进行了验证;探讨了压实曲线形状与土体物理性质的关系,并建立起了土体物理性质指标与全压实曲线方程参数之间的量化关系,这样我们便可通过对土体物理性质指标的量测,直接确定土体的全压实曲线方程参数及方程,从而为确定土体击实最大干密度和对应的最佳含水量提供了一种简便方法。
The results indicate:(1) the good gradation sample has good compaction property;(2) when coarse material content exceeds 75%,the largest dry density almost remains the same;and the compaction work should not too strong;and(3) th.
试验结果表明:级配良好的试样,压实特性较好;粗粒含量超过75%时,最大干密度增加不明显,此时,击实功不宜太大;等量替换法与大型击实试验结果接近。
