alignment
Quick Summary
Alignment, in an engineering context, refers to the proper positioning or state of adjustment of parts in relation to each other. In road design, alignment is crucial for creating a three-dimensional path for the road. This involves adjusting the road's course to balance excavated earth with the material needed for embankments, minimizing the amount of earth moved.12
Design standards, based on factors like traffic volume, speed, and safety, dictate elements such as the minimum radius of horizontal curves and maximum vertical gradients. These standards help define the actual alignment of the road, ensuring it is both functional and safe for drivers.2
