Zusammenfassung:The invention discloses a multi-index design method for full-particle-size brick-concrete solid waste for a cement-stabilized base layer. The method comprises the following steps: classifying brick-concrete regenerated coarse aggregate and brick-concrete regenerated fine aggregate according to the brick particle content, crushing index and water absorption rate of the brick-concrete regenerated coarse aggregate and the crushing index and water absorption rate of the brick-concrete regenerated fine aggregate; according to coarse and fine particle performance characteristics of recycled concrete and recycled bricks, typical particle grading types of different types of recycled coarse and fine aggregates are formed; the aggregate is prepared into a cement stable mixture, and the cement stable mixture is applied to different grades of urban road cement stable base layers. According to the method, the recycled aggregate is subjected to multi-index classification in a full-particle-size range according to the sourc
