Application of Cement Cold Regeneration Technology in Highway Maintenance
Cement cold regeneration technology is a kind of environmentally friendly and economical new technology and has been used in the maintenance engineering of beach road.In consideration of the engineering economy,field mixing and construction technology,ratio of cement and regeneration mixture is determined in the mix design to be 4∶100.The controlling of cement cold regeneration quality requires detection of the raw materials,inspection of grading and cement dose,and control of water content in the mixing plant.It is realized by rolling,paving and maintaining.The detection results show that the controlling of cement dose,water content and grading is relatively stable,and can meet the requirements of design and construction;the field compaction effect is good and the compaction degree can meet the construction requirements.
