Road base course material produced by engineering soil, and preparation method thereof

The invention discloses a road base course material produced from engineering soil. The road base course material comprises the following components in parts by mass: 70-100 parts of engineering soil,0-30 parts of construction waste recycled fine aggregate, a curing agent accounting for 5-9% of the mass sum of the engineering soil and the construction waste recycled fine aggregate, and water accounting for 12-18% of the mass sum of the engineering soil, the construction waste recycled fine aggregate and the curing agent. Correspondingly, the invention further discloses a preparation method ofthe engineering soil road base course material. By implementing the road base course material produced from engineering soil, the road base course material with high strength, good anti-scouring performance and low cost can be obtained, and the technical requirements of secondary primary roads and branch subbase layers of roads of two or less grades can be met. 本发明公开了一种用工程泥土生产的道路基层材料，其按照质量份计包括：工程泥土70~100份，建筑垃圾再生细骨料0~30份，二
