Zusammenfassung:The invention belongs to the technical field of road construction materials, and particularly relates to application of a composition in preparation of a stable material for pavements. The composition is prepared from the following components in percentage by mass: 5.25% of brick powder, 9.75% of fluidized bed combustion ash and 85% of aggregate, the brick powder contains active SiO2 and active Al2O3, and the fluidized bed combustion ash contains active SiO2, active Al2O3 and CaO with the mass ratio larger than 15%; the tensile bending strength of the composition is greater than or equal to 1.49 Mpa. The flexural-tensile strength variable coefficient of the composition is less than 15%, and the flexural-tensile strength can reach 1.49 Mpa and is improved by 7.8% compared with that of a common material; moreover, the compressive resilience modulus of the composition disclosed by the invention can reach 1410 Mpa, which is improved by 9.3% compared with that of a common material; therefore, the composition has a
