The Basics of a Good Road
We have known how to build good roads for a long time. Archaeologists have found ancient Egyptian roadsthat carried blocks to the pyramids in 4600 BCE. Later,the Romans built an extensive road system, using the same principles we use today. Some of these roads are
still in service.
If you follow the basic concepts of road building, you will create a road that will last. The mandments of a good road are:
(1)Get water away from the road
(2)Build on a firm foundation
(3)Use the best materials
(pact all layers properly
(5)Design for traffic loads and volumes
(6)Design for maintenance
(7)Pave only when ready
(8)Build from the bottom up
(9)Protect your investment
(10) Keep good records
water away from the road
We can’t overemphasize the importance of good estimate that at least 90% of a road’s problems can be related to excess water or to poor waterdrainage. Too much water in any layer of a road’sstructure can weaken that layer, leading to failure.
In the surface layer, water can cause cracks and potholes. In lower layers it undermines support, causing cracks and potholes. mon sign of water in an asphalt road surface is alligator cracking — an interconnected pattern of cracks forming small irregular shaped pieces th
