9-1 General. The culvert design begins when the Structure Design Unit receives the Culvert Survey and Hydraulic Design Report from the Hydraulics Unit. This report in conjunction with the Roadway plans shall be used to compute the culvert length, design fill, and other items that lead to the completed culvert plans.
Design of Box Culverts. A culvert is a drainage structure designed to pass on storm water or stream of constrained flow over a street. Culverts can comprise single or multi-span development, with a base inside width of 6 meters when the estimation is made horizontally along the centreline of the street from eye to eye of side dividers.

Although a bridge overpass was initially considered, an underpass constructed with reinforced concrete box culverts provided the quickest, most cost-efficient, and reliable solution. The underpass design spanned the two active rail lines and specified 48 sections of 12- by 10-foot precast boxes, weighing approximately 33,000 pounds each.
Two laboratory tests were conducted to investigate the mechanical properties and develop a load-carrying capacity estimation method for reinforced concrete (RC) slab culverts rehabilitated with a ...
Height: The depth of cover requires a design according to AASHTO LRFD, but usually requires a minimum of 2 feet (0.6 m), especially when highway loads are being designed for. If the available cover is not sufficient, you can back up to the hydraulics stage and reduce the culvert size. If you've squeezed the smallest concrete box culvert you ...
Concrete pipe culverts come in a variety of sizes and shapes. The size of the culvert you need will depend on the amount of water flowing under the roadway and the space available for the culvert. Benefits of Concrete Pipe Culverts One of the main advantages of concrete pipe culverts is that they are extremely strong and durable.

A culvert is a conduit or passage that allows water to flow under a road, railroad, trail, or similar obstruction. Culverts come in many shapes and sizes, typically made of concrete, galvanized steel, aluminum, or plastic. Culverts are installed where it is necessary to maintain proper drainage and prevent flooding.

Distribution Slab means a reinforced concrete slab on top of the culvert that may be specified when the earth cover is less than 600mm to improve load distribution on a culvert. Element means an individual precast concrete culvert unit. Excavation, Earth and Rock means the excavation of material classified as earth and rock according to OPSS 902.
See Table 3 for the loadings considered for culverts. These loadings and associated factors are discussed in more detail in the following section. 8/15 Technical Manual 25 BRASS-CULVERT™ For BRASS-CULVERT™, the only material option is reinforced concrete, as the program only considers precast and cast-in-place concrete box culverts.
Maximum height of water inside the culvert is 1.8m above the invert level of the culvert. Backfill material will be Class 6N with a density (γ) = 19kN/m 3. Fill over the culvert consists of 0.5m of Class 6N overlaid with 0.3m of road sub-base with a density (γ) = 20kN/m 3 and 0.2m of carriageway construction with a density (γ) = 24kN/m 3 ...
