Road construction was an extremely arduous task; first, it was necessary to fill all the pits and uneven spots on the road. After leveling, a mixture of lime with stone materials would be spread over the path, stabilizing the soil to a depth of at least twenty to thirty centimeters.
Then, green bricks would be laid on top, one by one, just like building a house.
At that time, without machinery, every task required manpower. The stable soil, made from lime and stone materials, had to be transported by pushcart. In the absence of enough livestock, people had to step in and haul the pushcarts themselves.
A cartload of soil could weigh several hundred pounds, so when pulling the pushcart, a person would use a rope, one end tied to the cart and the other end slung over their shoulder, proceeding forward with the force exerted through their shoulders as if they were beasts of burden.
