Route surveying

Route surveying

Hi there, Is there need for route surveying during a road upgrading project?

RE: Route surveying

If you are changing the centerline or widening the road, yes.

Thanks Ron for the response, but specifically what do you need to pick up during the survey if you're to change centreline or widen the road?

RE: Route surveying

Define the new centerline, the pavement edge, the shoulders, drainage features....then cross sections and longitudinal sections

RE: Route surveying

The level of detail necessary really depends on the importance of the road you are analyzing, but as a general rule, for geometrical purposes you should complement the regular survey with some more detailed 'classical' survey.
Furthermore, all the pavement, drainage and signaling features should be registered thoroughly.

RE: Route surveying

It also depends on what the project proposes to do.

For a single course "mill and fill" (grind off the top course asphalt and pave a new layer oftop course), not much detail is needed. Mostly lengths, widths, pavement marking quantities, in-pavemtn signal detection hardware that may damaged by the milling, etc.

If you are planning a more involved rehabilitation or complete reconstrctuin, then much more detail is needed, such as cross slopes, profiles, locations of roadside objects, drainage structures and problems, etc.
