    To apply construction waste to road engineering construction, the variation law and multiple influencing factors of the road performance of cement stabilized construction waste recycled materials with different mix ratios were explored. The multiple construction waste content (volume fraction of 20%, 40%, 60%, 80%, and 100%), three brick concrete ratios (brick concrete volume ratios were 1∶1, 1∶2, full concrete) and two cement content (mass fraction of 4% and 5%) were used for mix ratio design. A systematic study was conducted on the road performance and its variation patterns through compaction, unconfined compressive strength, splitting strength tests, water stability, frost resistance and dry shrinkage tests. The grey relational analysis algorithm was used to analyze the degree of influence of different mix ratio variables in aggregates on road performance. The results indicate that with the increase of construction waste content, brick concrete ratio and cement content, the unconfined compressive strength, splitting strength, water stability and frost resistance of recycled materials at 7 and 28 d all decrease. The dry shrinkage coefficient increases with the increase of cement content, and the correlation degree between the mix ratio variables and road performance from high to low is cement content, construction waste content and brick concrete ratio. When the cement content is 4%, the construction waste content is 80% and the brick concrete ratio is 1∶2, it can still meet the grassroots requirements of secondary and lower level highways for medium and light traffic.
