Study on Performance of Normal and Compaction-Free Porous Concrete Permeable Base

Abstract:

Moisture damage is one of the main forms of early failure in the pavement. Water can be released from the road structure by setting porous concrete permeable base. The common construction technology for porous concrete is traditional vibration compaction, which is helpful for the strength formation of the base. However, it is unhelpful for the stability and smoothness of the base during the construction. In this study, compaction-free porous concrete (CPC) permeable base was proposed, which can not only satisfies both porosity and the structural strength, but also guarantees the stability and the smoothness of the base during construction. The performance of normal porous concrete (NPC) and CPC, such as strength, drainage capacity, shrinkage and frost resistance, were studied in the paper. The laboratory tests show that all of them have good performance. In addition, the field evaluations, such as strength, drainage capacity, deflection, smoothness of the base, were tested. The results show that both of NPC and CPC have good drainage capacity, and the strength of NPC is higher than CPC, but the smoothness of NPC is weaker than CPC.
