The Smart City means different things to different people. It essentially considers quality of life and how this can be achieved for current and future generations. This paper considers a Smart pavement construction material that is predominately composed of waste materials and involves very little energy use. It considers the potential use of specially-formulated geopolymer grouts to infill the internal void structure of a porous aggregate skeleton made using Reclaimed Asphalt Pavement (RAP). The use of by-product materials in the geopolymer grout offers an alternative to cement based grouting systems. The paper summarises the relationships among mechanical properties including compressive strength and stiffness, flowability, setting time, and void-filling efficiency of porous RAP with geopolymer grouting. The low energy creation of a single size particle RAP layer with internal voids filled with geopolymer grout offers an alternative use of what may traditionally be regarded as low value industrial waste materials. There is considerable scope for development of this type of pavement layer in Smart Cities.
