Cracking Risk Appraisal of High Performance Recycled Pavement Concrete and its Application
Based on the technology of high performance concrete, high performance recycled pavement concrete (HPRPC) were developed by double -mixture of fly ash and superplasticizer. The dry shrinkage and plastic shrinkage cracking evaluation test were conducted. As is shown by the results, the compressive strength of HPRPC at 28d are exceed in 60MPa and dry shrinkage at 120d are less than 500με. By contrast, the cracking -resistant performance of HPRPC-7 is superior to that of HPRPC-2.
