The invention discloses an anti-shrinkage construction waste stabilized road base material and application thereof, and belongs to the field of road engineering. The base material comprises construction waste mixed aggregate, cement, an anti-shrinkage stabilizer and water, the construction waste mixed aggregate is composed of crushed concrete aggregate and crushed brick aggregate, and the anti-shrinkage stabilizer is composed of polypropylene fiber, titanium gypsum, a water glass-based exciting agent and steel slag. When the anti-shrinkage construction waste stabilized road base material disclosed by the invention is used for paving a road base, engineering index requirements can be met, good shrinkage performance can be ensured, and environmental protection requirements can also be met when construction waste regenerated granules are used as a base filler. And meanwhile, the designed pavement structure can greatly reduce the use amount of road building materials, has obvious effects in the aspects of realizi
