By the cement, lime, fly ash and other inorganic binder and the formation of semi-rigid, because the material has a high temperature shrinkage and shrinkage, which makes the semi-rigid in the temperature, humidity, environmental factors, often appear first cracking and reflection to the asphalt conc

The cement, lime, combined with inorganic materials such as coal ash formed by grass-roots, as a result of their semi-rigid material with a high temperature and dry deflation deflation characteristics in the grass-roots, and makes semi-rigid temperature, humidity, and environmental factors are often

By the cement, the lime, the pulverized coal ash and so on the semi-rigid basic unit which forms with the inorganic binding, because its material has high warm shrinks with the air shrinkage characteristic, causes the semi-rigid basic unit in the temperature, under the humidity environmental factor

Made of cement, lime, fly ash and the formation of inorganic binding materials, such as semi-rigid base, because of their material has a high temperature shrinkage and drying shrinkage characteristics, making the semi-rigid base in temperature and humidity under the effect of environmental factors,
