| The production of concrete is a process of high energy production,If we can make good use of waste concrete,to achieve the effect of regeneration,Then it is bound to contribute to low-carbon environmental protection.This paper is mainly to consider the use of waste concrete to prepare recycled aggregate,Due to the high water absorption of recycled aggregate,the use of roller compacted concrete technology to prepare dry hard concrete.Combined with highway-related procedures,and through the analysis of material properties and structure,Research on Roller Compacted Concrete for Recycled Aggregate Pavement.In this paper.The prepared recycled aggregate has an extremely important effect on the later preparation of concrete,Therefore,according to the characteristics of recycled aggregate,This Will analyze the different crushing methods of the preparation of recycled aggregate performance parameters including Needle-like 、Crushing index、Water absorption and so on.And Compared with the performance parameters of natural aggregate under the same test conditions,The concrete of the corresponding crushing method is prepared,and the difference between the concrete prepared by the recycled aggregate is obtained,According to the parameters of the test parameters,the various types of broken concrete prepared by the comparison,and concluded.In the test of roller compacted concrete,Mainly used in this group is used to simulate the construction conditions under the rolling molding device,Making the roller compacted concrete specimens formed in the laboratory closer to the construction of the rolling road concrete.Orthogonal test method.Using the volume method to calculate the mixing ratio,the factors of the recycled RCC were analyzed,Combined with improved VC value,strength,wear resistance and so on were studied,And finally the proportion of recycled RCC is preferred.According to the obtained mixture ratio,various kinds of recycled roller compacted concrete.This paper studies the parameters of different kinds of recycled RCC,and draws the conclusion and provides the reference for the stress analysis of recycled roller compacted concrete pavement.Combined with the parameters obtained in the experiment,combined with the relevant specifications,the stress analysis software of the recycled aggregate road RCC was obtained by using the pavement stress analysis software.In this paper,through the study of recycled aggregate concrete RCC,this green production can be produced in the way of aggregate and pavement Ridge concrete effectively combined.So that it can play its environmental characteristics,but also can be prepared in line with highway specifications of the road roller compacted concrete.The results of the study can also provide a reference for the future large-scale utilization of recycled aggregates,as well as the combination of road roller compacted concrete technology. |
