You can build an extra thousand square metres in your front lawn or a garage by installing a small gravel driveway.
The idea is to make a driveway more durable and provide better drainage.
It can also be a fun way to make space for plants and other landscaping.
“There are a lot of areas that are neglected and neglected by the road,” Dr Dermot Larkins from the University of Queensland said.
“We’re all familiar with that, the driveway is one of those.”
Dr Larkings team is now working on creating more durable concrete roads.
They’re using a mix of gravel and clay to build the asphalt, and then sanding it down with a mix that will provide a layer of clay and sand.
“You have to have some clay that’s hard to get down the sides, some clay underneath the road, and some sand to hold the clay,” Dr Larkers said.
A project called “Roadsand” by the University at Albany has used clay and concrete to create a new asphalt road.
“They were able to create an entire road that was about 10 times more durable than conventional asphalt roads,” Dr Gao said.
Dr Larks team says the project is already showing results, but more work needs to be done.
“Our primary goal is to get more and more people using these roads, because we know that when they are installed properly, the extra cost is offset by increased productivity,” he said.
