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.

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.

Experimental research on compaction characteristics of aeolian sand;

The conclusion is given by analyzing the result and compaction characteristics,which says that each compaction is associated with one maximum dry density.

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.

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.

Study on site compaction characteristics for rockfill material;

Analysis and study of influences of compaction characteristics of roller on highway compaction;

By building test road,this paper studies the compaction characteristics,the geogrid in situ and long term deformation of geogrid reinforced embankment with steep slope.
