Moisture damage is one of the main forms of early failure in the asphalt pavement. Setting porous concrete permeable base can release water from the road structure. The common construction technology for porous concrete is traditional vibration compaction, which is helpful for the strength formation of the base, but unhelpful for the stability and smoothness of the base.In this sdudy, Compaction-free Porous Concrete (CPC) permeable base was proposed, which can not only satisfies the strength requirement of structures, but also guarantees the stability and the smoothness of the base. The idea of volume method was adopted on mix design of CPC. Mix proportion parameters such as aggregate dosage, cement dosage and water dosage were calculated and confirmed based on experimental study. The performance test results show that CPC designed by this method can satisfy the design standard. Accordingly, the design method of CPC is feasible.
