Cross slope, cross fall or camber is a geometric feature of pavement surfaces: the transverse slope with respect to the horizon. It is a very important safety factor. Cross slope is provided to provide a drainage gradient so that water will run off the surface to a drainage system such as a street gutter or ditch.
Typically on straight road sections, the drainage gradient is at least 1–3% due to the normal cross slope of 1–3%. In curved sections the drainage gradient is higher, and may often reach 5–12% due to superelevated CS that may reach 5–8% in areas with icy roads and up to 12% in areas without icy roads.
l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A ...
A crawl space can be susceptible to flooding, a risk that is sometimes mitigated by such measures as using rain drainage such as rain gutters to conduct rainwater away from the house and sloping the earth away from the house. [8] Crawl space wall materials may include, e.g., solid concrete or concrete masonry units. [9]
Tumblehome or tumble home is the narrowing of a hull above the waterline, giving less beam at the level of the main deck. The opposite of tumblehome is flare . A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves .
A driveway (also called drive in UK English) [1] is a private road for local access to one or a small group of structures owned and maintained by an individual or group. Driveways rarely have traffic lights , but some may if they handle heavy traffic, especially those leading to commercial businesses or parks.
A trail of clues — including an oil leak, security video and data from a truck's onboard computer — lead S.C. investigators to a jealous man suspected of running down a romantic rival.
They illustrate how the home relates to the lot's boundaries and surroundings. Site plans should outline location of utility services, setback requirements, easements, location of driveways and walkways, and sometimes even topographical data that specifies the slope of the terrain. A floor plan [2] is an overhead view of the completed house. On ...
