From some of the emulsified asphalt cold regeneration test road disease survey found that less than two years after the opening of some sections began to appear serious transverse cracks, turtle crack, pit and other diseases. In order to analyze the cause of the disease, the core of the pavement core was taken and the splitting test was carried out. The results showed that the disease occurred in the cold regenerated layer of emulsified asphalt, and the splitting strength of the core was more than 0.4Ma. Indicating the use of nearly two years after the emulsification of asphalt mixture splitting strength to meet the design requirements of the case occurred early disease. Therefore, in the design of emulsified asphalt mixture should improve the splitting strength of the mixture to ensure that the emulsified asphalt cold recycled material carrying capacity to extend the life of emulsified asphalt cold regeneration.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery
With the increase in the amount of cement, the strength of the mixture also increased, the test also found that when the amount of cement increased, the cement hydration of water consumption also increased, so the mixture of emulsified asphalt demulsification rate also accelerated The Therefore, in determining the amount of cement is to consider its impact on the strength, but also to consider its impact on the construction, the proposed amount of cement should be controlled within 2%.
