Cracking makes supercrust generate reflection crack.Cement stabilized macadam base will appear crack, be because the intensity of During Initial Stage Construction is higher
And the heat that the hydration of cement is sent out so that the crack of the structure drying shrinkage and temperature contracting.It is worse to be laid with road when the later stage
When the layer of face, these cracks can then reflex to road surface, generate reflection crack, either large or small destruction is caused, to influence road
Service life and stability；Cement Stabilized Gravel Base Evenness be difficult hold, rubble itself all be or small Shi Tidou
It is very small and unstable.When the grading of rubble is undesirable, and in the presence of also having saline and alkaline Stone sometimes, may result in
It is difficult that lay is smooth, and rubble cannot mix well with cementitious materials such as cement and generate isolation, cement when being laid with road surface
Stablize the insufficient strength of graded broken stone.To its bearing capacity and service life, cement stabilized macadam base goes out the strength relationship of road
Existing intensity is insufficient the reason is that base's sample core is not up to standard, and when mixture gradation is unreasonable and concrete grey dosage or fine grained it is inclined
Hour can all lead to cement stabilized macadam base insufficient strength, influence the bearing capacity and service life of road.
