Settlement is a crucial factor when designing a foundation. The number of lanes, cross section, level of service, sight distance, alignment, lane width, and other factors must be taken into account when planning highways.
Telford and Macadam simultaneously established the road foundation for the development of modern roads.
Highway drainage is the removal of extra surface and subsurface dirt from the road or right-of-way.
Map research, reconnaissance, preliminary survey, and detailed survey are the 4 stages that the surveys go through before being finished.
