The invention relates to a roadbed structure close to a highway pier, and belongs to the field of construction. The roadbed structure comprises a roadbed, edge slopes on the two sides of the roadbed and inclined outwards, protective slopes on the two sides of the roadbed and a water proof bottom layer, wherein the edge slopes are provided with reinforced concrete layers, and the reinforced concrete layers are formed by pouring of elastic concrete; and the elastic concrete is prepared from the components in percentage: 20-30% of cement, 4-8% of coal gangue, 10-14% of lime, 40-50% of aggregate and the balance of water. According to the roadbed structure close to the highway pier, the effect of guaranteeing stabilization and non-deformation of the roadbed below a pavement can be achieved, meanwhile water discharging and blocking are facilitated, water on embankments can be rapidly discharged from multiple layers, and the problems of frost heaving, thaw collapse and frost boiling of the roadbed are effectively prevented.
