A novel integral noise barrier (INB) composed of steel fiber reinforced cementitious composite (SFRCC) and basalt fiber reinforced plastic (BFRP) is put forward in this paper. Compared with traditional noise barrier, INB integrated sound-absorbing panel, H type steel, autoclaved lightweight concrete (ALC) bridge guardrail panel into a whole. The basic design idea and experimental method for INB are described. Based on the engineering demand for eastern extension project of the No.2 subway line of Nanjing, six specimens were cast and tested under simulated positive and negative loads. Under the design loads, six specimens did not crack and the lateral displacement on the top of the slab is less than H /250, where H is the height of INB. The experimental results show that INB can meet the design requirements of eastern extension engineering of the No.2 subway line of Nanjing.
