Road Resurfacing Machine (Recycle)
To decrease costs of resurfacing a road and reduce amount of asphalt used. The idea would be to design a paving machine which uses microwaves to heat up old asphalt on the road and enabling it to be picked up easily. The machine would then remix the asphalt to the proper ratio by adding extra asphalt tar and then resurface the road all in a single operation with the same machine. This machine would eliminate the system used presently whereby pavement is stripped, new pavement is brought in days later and the road is resurfaced weeks later.
Reward: New roads resurfaced cheaply with less noise and disruptions.
