The invention relates to the technical field of pavement materials, in particular to a super-high-toughness cement base composite for a road and a preparing method and application of the composite. The composite comprises, by mass, 20-25% of cement, 30-35% of coal ash, 10-15% of water, 1.5-2% of fiber, 30-35% of sand, 0.1-0.3% of a water reducing agent, 0.02-0.03% of a thickening agent. The composite further comprises a polymer modifier accounting for 10-25% of the mass of the cement. The polymer modifier is composed of a high-molecular emulsion and a modification enhancer according to the mass ratio of (1.2-1.9):1. The composite has excellent durability, impact resistance and fatigue resistance; the composite can better solve the pavement durability problem after being applied to a traditional asphalt pavement structure, and the service life of the pavement structure is remarkably prolonged.
