Properties of the vibration molding cement cold recycling mixture are tested using a series of laboratory experiment and are compared with the same properties of statically pressed specimens. It is found that with the same cement content and under the same curing condition, vibration molding specimens have such better mechanical properties as compression strength, splitting tensile strength, resilience modulus as well as better performance like frozen stability and erosion resistance. The study also shows that the same property requirement can be achieved at lower cement content if the vibration molding is employed. The vibration molding method can not only save cement, but also enhance the anti-cracking property of the recycled base. The use of vibration molding should be promoted.

In order to study the factors which influence the inorganic binder stabilized material's compaction test results, different recycled material content therefore different reclaimed gradation mixtures are tested while varying the amount of cement. The experiment results show that contents of the recycled base material and the recycled surface material on the compaction test results are determined by the change of their density and water absorption ratio. Dry density of the recycled mixture increases with the increase of the reclaimed base material density. Low water absorption ratio of the recycled material reduces the reclaimed mixture's optimum moisture content. Density of the reclaimed wearing surface material reduces the maximum dry density of the reclaimed mixture because the old wearing surface material has lower density. Its low water absorption reduces the optimum moisture content of the recycled mixture. Influence of cement content on compaction test results is the increase of the cement content can enhance the maximum dry density and optimum moisture content of the recycled material. Through the analysis of the results of the compaction test, the key factors in the recycled material compaction test are unveiled. © (2012) Trans Tech Publications, Switzerland.
