The cross sections of a typical water bound macadam road are a graphical representation of the conditions that already exist or the work that needs to be done within the station limits of a roadway. The most important part of a roadway is represented by a typical cross section, which also outlines the most important components. During the ancient era, Water Bound Macadam roads were built. since very. These roads have a wearing surface that is made up of clean, crushed aggregates that are mechanically interlocked by rolling and bound together with a filler material and water. They are called Water Bound Macadam (W.B.M) roads, and they are laid on top of a prepared base course. By rolling, the crushed aggregates are bound together with the filling material with the help of water. Because of this, it is sometimes referred to as Water Bound Macadam (W.B.M). In general, a macadam is a layer of road that is comprised of a single-sized crushed stone layer of small angular stones that are placed in a shallow thickness and compacted thoroughly to improve the bearing capacity of road crust in layers by rolling where the voids get rolled and give the top a leveled surface. This process is done to create a macadam. Now, in WBM, the surface that has been rolled is covered with earth that has been mixed with either crushed cinder stones or crushed red stone sand in order to break the plasticity of the earth. 
This earth, when watered by sprinkling profusely, forms a paste that creeps into the voids in the stone aggressive to interlock them by getting filled up in voids, and this layer, which is called the water bound madam layer, has more strength than the mac In order to elaborate further on cross sections, it is important to note that it is not appropriate for typical cross section sheets to include alignment geometrics or super elevation information. The plan sheets are where that information is going to be displayed. ditches, shoulders, pavement surfaces, and median width (dimensioned vertically and horizontally), fore slopes and back slopes (labeled with the slope), and sub drains, barriers and curbs are the primary elements that are typically displayed on a typical cross section (identified by type). The horizontal dimensions of the roadway on typical cross sections should be expressed in feet and should reference either the alignment or the baseline. When displaying horizontal dimensions, round up to the nearest half-foot increment whenever possible. If a horizontal dimension is given down to the nearest foot, then the dimension should be shown as a whole number. (A lane that is 12 feet long would be written as 12' rather than 12.0'.) For both new construction and existing conditions, the vertical highway dimensions on the typical cross section should be given in inches and indicated to the nearest half inch. 
This applies to both existing conditions and new construction. The vertical scale is typically depicted at an exaggerated size in order to make the various layer thicknesses clearer. When describing the cross slope of a feature, percentages should be used with an arrow pointing in the direction of the downward slope, or, if applicable, the cross slope should be depicted as matching the existing slope. The ratio of the horizontal to the vertical should be used to identify the side slopes. On the typical cross sections for grading and paving, the location of the profile grade should be shown in a clear and legible manner. In the same way that a cross section illustrates the various components of a typical road, we are going to go through some of the components of a typical road. The width of the road, the cross slope, the pavement, the road borders, the traffic separators, and the curbs make up the fundamental elements of the highway. These geometric components are developed with the psychology of the driver, the characteristics of the vehicle, and the volume of traffic in the location all playing a role in their conception and influence. The competent fulfillment of these management responsibilities is what guarantees the safety of the highway. 
- Slope using a Cross or Camber
The slope that is supplied in the transverse direction of the pavement or carriageway is referred to as the cross slope or camber. The road surface is helped to drain of rainwater by the diagonal slope that runs across it. An inadequate cross slope will lead to water spilling over the pavement, which will eventually lead to the deterioration of the highway. The amount of precipitation that occurs in the area as well as the sort of materials that were used to create the road both have an effect on the slope's value. The value of the cross slope might range anywhere from 1 in 60 to 1 in 25 most of the time.
- Roadway or Pavement for Vehicles
The paved segment of a highway or road that is intended for use by moving traffic is referred to as the pavement or the carriageway. The width of the pavement is going to be determined by the width of the traffic lanes as well as the number of lanes that are going to be built. The roadway or the pavement that is constructed for the flow of one line of vehicles is referred to as a traffic lane. In general, for single lanes that have a maximum width of 2.44 meters, it is preferable to have a width of 3.75 meters for the lane itself. It is recommended that a width of 3.5 meters be maintained on sidewalks that are planned to accommodate two or more lanes of traffic.
- Medians
Traffic separators known as medians have the primary purpose of preventing head-on collisions between vehicles traveling in opposite directions on adjacent lanes. This is accomplished by placing the medians between lanes of traffic.
- Curbs
Curbs are a term used to refer to the edge of the pavement that separates it from the shoulder. For urban roadways, the installation of curbs is a desirable improvement.
- Road Margin
Shoulders, bus bays, parking lanes, and sidewalks or footpaths are all considered to be part of the road margin. Shoulders are the paved areas that run along the side of the road. This area is designed to accommodate vehicles that are required to be moved off of the pavement or the roadway in order to complete maintenance or repairs. These lanes also serve as a service lane for vehicles that have experienced mechanical difficulties. The curb is recessed in order to create bus bays, which are also known as "stops." Because of this, there won't be any problems with the moving traffic.
- Roadway width
The width of the roadway, also known as the width of the formation, is equal to the sum of the widths of the pavement, including any separators that may be present, as well as the shoulders.
- Right of Way
The term "right of way" refers to the section of land that was purchased along the path of the road in order to construct it. The measurement used to determine land width is the width of this acquired land. The right of way is determined by the significance of the route and the likelihood of development in the area in the near future. If you require more information, make sure to contact us.
