Hardy wear by trafficRoad drainage:“Water is the great enemy of roads” It soft in material of road construction, Due to expansion and freezing. It Disintegrates the road bed.The necessity of road drainage:Water standing on the-road, interfere with the movement of the-road trafficStanding water cases damage to the road surface-even pot holes are createdwater excess in the sub soil reduce its bearing capacity, failure of road due to sinkingFrost actionSource of water:From rain directly falling n the road surfaceDischarge from the surface of adjoining landFlooding of water coursesPercolation through the soil under the roadType of water:Surface waterSubsurface waterType of road drainage:Surface water drainageFactor affecting the DesignRainfallRunoffCatchments areaRunoff factors= Runoff/ Total rainfallDisposal of surface waterCamberSide drains (Open ditches) Q=AV (Q=Runoff in cusecs, A=Cross Sectional area Sq Feet, V=Velocity Feet/SecGradientsPiped surface water drainsCatch-water drains: (Interception ditches)Cross drainages Culverts (A culvert is a drain provided to convey water transversely under a road way).

Its top surface is called the formation which is trued up by the graders or labor before laying

SOFTWARE :AEC CutFillVERSION :1.0PLATFORM :WindowsLICENSE :TrialDOWNLOADS :UserDownloads:3609Program DescriptionFor grading and excavation contractors and clients who need cut and fill volume quantity information, is an earthwork program that provides a solution for traditional cross section project work. AEC CutFill is a powerful and flexible earthwork cut and fill calculation software program. AEC CutFill can be used to determine volumetric quantities by the Average End Area Method. AEC CutFill calculates quantities for nearly any earthwork application, including roadways, runways, ditches, borrow pits, site preparation, building excavations, parking lots, retaining walls, mining applications, land developments, and more. AEC CutFill takes your cross-section data for both existing and proposed ground levels and calculates the volume of earth to be removed and added. Cross sections are plotted and profiles are plotted in DXF File format and station and total quantities are calculated. * AEC CutFill download link provides trial version of the software.Similar Software3D Building Quantity ManagerAEC Buildings is a project quantity estimation and 3d drawing tool to quickly prepare your designs, drawings, dimensioning and quantity estimation.Create Digital Elevation Model from AutoCADAEC Terrain is designed to simplify terrain management and 3D-modeling.Estimate The Resources Under Project ExecutionThe AEC Budget as an innovative budgeting tool that helps the user to estimate the resources under project execution, making it to plan by extending tight integration to MS ProjectRC Designer and DetailerAEC 3D Rebar, is the same functionality as that of a structural engineer, a draftsman, a detailer and an estimating engineer working all together from concept to completion
