Study on Thin Layer Porous Pavement Method to Save Energy and Cost

摘要

With the natural quality resources being increasingly cvnsumed, the pavement repair method utilizing recyclable materials from the other industries such as steel slag is today more anticipated, for its capability of resource-saving, cost-reduction and minimizing CO2 emission. The method we developed has shown about 15% of cost and 20% of CO2 reduction, compared with the conventional method, by utilization of recyclable resources from the other industries and by adoption of thin cut and overlay on thick tack coating. Herein, we intend to verify the feature of this method by means of various indoor tests and several experimental field-pavements, and consequently will confirm that the section of repaired pavement stands workable from the viewpoint of the layer structure analysis (elasticity theory).
