What is a profile of a road?

Table of Contents

Actually, a road profile is a two-dimensional slice of the road surface, taken along an imaginary line. Longitudinal profile shows the design grade, roughness and texture3 (see Figure 1).

What is L section and cross section?

Longitudinal Section. A Long Section is a profile view of a surface along a particular route, which plots elevation against the distance along the route e.g ground profile along the center line of a road, railway or river. In a long section, elevations are determined along a fixed route. Cross Section.

What is L section in civil engineering?

Definition: A section taken through the lengthwise dimension of a structure. It can also be termed as the Side Elevation of a structure. A typical longitudinal section of a road: L Section of Road.

What is profiling in road construction?

Profiling – or cold milling – is the basis for new road profiles. Layer by layer removal of damaged road surfaces allows for the separation of materials for re-use or disposal. Cold milling is an especially quick and economical construction method where removal of existing material is required.

What is road cross section?

A roadway cross section is a vertical section of the ground and roadway at right angles to the centerline of the roadway, including all elements of a highway or street from the right-of-way line (lanes, shoulders, retaining walls, curbs, medians, pavement structure, roadside slopes, ditches, bike lanes and sidewalks).

What is Profile levelling?

Profile levelling is the process of levelling along a fixed line to determine the elevations of the ground surface along the line. Profile levelling is also known as longitudinal sectioning.

What is road cross-section?

What is the difference between profile Levelling and cross sectioning?

There is really no difference in procedure between profile and cross-section leveling except for the form of the field notes. Cross-section rod shots are usually taken during the route profile survey from the same instrument positions used to take rod shots along the centerline.

What are asphalt Profilings?

Asphalt profiling requires the use of special machinery to remove asphalt to a certain thickness with the intent on making it level with a sleek finish. Profiling machinery must only be operated by trained professionals and here at J & G Excavations & Asphalting we employ some of the best in the industry.

What is milling in construction?

Milling is the process of removing the top layer of asphalt to a specified and even depth without disturbing the underlying subbase. This allows new asphalt to be laid down without increasing the height of the road and saves you time if the subbase doesn’t need to be fixed.
