摘要：	The increased emphasis on reducing the energy needed to manufacture products of all types, usually as part of a drive to reduce greenhouse gas emissions, has encouraged, amongst other things, a move towards asphalts that can be mixed and compacted successfully at lower temperatures. Advera® WMA, a product intended to allow a reduction in the mixing temperature from around 160 °C to nearer 120 °C, was trialled during the surfacing of an access road to the car park of a quarry near Shrewsbury. The construction of this pilot scale trial was monitored and the results are reported. The monitoring included the construction, the resulting material properties, the carbon dioxide equivalent emissions and the temperature changes with time after compaction. The findings show that, whilst the modified asphalt at lower temperatures was not identical to the control mixture, a mixture could be laid at significantly lower temperature without significant adverse effects and with lower CO2 emissions.
