Research on performance test of lime-flyash stabilized coal spoil used as the base of pavement;

Considering the effect of the old lime-soil content, lime-flyash content and lime-flyash ratio on lime-flyash- stabilized reclaimed asphalt pavement materials, an orthogonalexperiment research on compression strength, split tensile strength and compression modulus of lime-flyash-stabilized reclaimed asphalt pavement materials is carried out.

In this paper,so the infheence of the lime-ash and polymer solidified material-SH on the physical and mechanical capability was studied systematically from mechanics strength and deformation characteristic property that provided a basis for application.

In this paper, the object of study on subbase material is lime fly ash stabilized aeolian sand.

A new kind of proportioning design method based on cubage analysis of phosphogypsum modification lime fly-ash road base material was brought forward through the series of test and the mechanism of its strength development.

Especially,the subbase structures usually adopt lime and fly ash stabilized fine-grain soil(lime-ash soil for short)to replace previous common lime stabilized soil,that improves the engineering quality and service quality of road further.

This paper studies the change of lime reduction of lime-ash soil under the following three conditions in an inside experiment,such as low temperature,stable temperature and exposed found.

Because of many merits, such as higher strength, better water stability, convenient for construction and good for environment protection, lime-ash soil is widely used now in high class highway sub-base.
