New software for quantifying the systematical energy consumption, resources consumption and waste disposal information in road construction has been set up and was named as SEE-at-GRC (Systematical energy and environmental assessment tool for Green road construction). With help of this tool, the quantified contributions of recycling waste materials or modified materials in road construction as well as process improvement etc. on environmental impact can be evaluated by showing savings on energy consumption and resource consumption quantitatively; at the same time waste disposal capacity and environmental impacts were also provided. Two examples were given to shown the output of the software. Those results are useful for guiding the utilization of recycled waste materials, as well as for developing new technology process and advanced materials in road construction. Based on Visual Basic (VB) language and MSSQL database, SEE-at-GRC has provided a full set of evaluation methodology on energy saving, emission reduction and process optimization for guiding green road construction developing.
