Fine-grained exposed aggregate Portland cement concrete (PCC) pavement has been successfully used in Europe and Japan as an alternative solution to simultaneously reduce the noise level of PCC pavement and to enhance long-term skid resistance.This study aims to investigate the fundamental properties of the exposed aggregate PCC pavement, and expects to provide useful information for design and construction.

Understanding of current asset condition and future asset performance is lacking in most authorities for their highway assets, such as road markings or road lighting columns. A number of life-cycle planning tools are available to develop life-cycle plans, both deterministic and stochastic in nature. The challenge in including ancillary highway assets in a stochastic modelling process is the determination of the current condition of the assets, represented by a distribution of condition, and the modelling of deterioration, represented by a transition probability matrix.

This paper presents the results of a pilot for the CMS road infrastructure projects tool to provide a transparent mechanism for reporting infrastructure project carbon dioxide emissions at construction stage. Two further case studies demonstrate how the tool informs carbon dioxide analysis and optimisation through design. These investigate the potential carbon benefits of ‘crack and seat' processes, the use of long-life pavement material and the need to carefully examine the transport implications of recycled content specifications, in delivering a ‘lower carbon' infrastructure solution.
