Mass and haul diagram
The mass haul diagram is a traditional and valuable tool for road design some of the quantities calculated with the optimal haul are automatically included in the mass haul diagram open the softree optimal application. Mass diagram (mass curve) general: embankment and excavation volumes for an entire project are summarized in the form of a mass diagram, wh ich is an extremely useful tool in the. Obtained by means of the mass haul diagram, l„,, between the centers of gravity, is therefore unjustified in order to safeguard himself against losses imposed by this method of measurement, the contractor will probably augment bid rates for hauling only, r, by a quotient, a, defined as.
Ufreehaul, overhaul, and mass haul diagram: normally, cost of excavation includes cost of transporting of material (unwanted soil) from either cut or fill for a maximum distance called the ufreehaul distance (fhd) u, but transporting of material for a distance grater than freehaul is called uoverhaul distance. Earthwork mass diagrams basic definitions average haul determined from mass diagram average haul is the area of the mass diagram representing the number of cubic yard stations of haul between balance points divided by the ordinate of the mass which the yardage is hauled. Freehaul, overhaul, and mass haul diagram: normally, cost of excavation includes cost of transporting of material (unwanted soil) from either cut or fill for a maximum distance called the freehaul distance (fhd), but transporting of material for a distance grater than freehaul is called overhaul distance (ohd.
The mass haul diagram or curve is drawn in accordance to the calculation of earthwork volumes and its ordinates that describes cumulative volume at specific points along the center line a simple way to understand mass haul diagram is to imagine a truck that’s moves along the length of the projects in the direction of increasing stations. A mass haul diagram consists of two objects: a mass haul line, and a mass haul view the mass haul line represents the free haul and overhaul volumes in cut and fill conditions along an alignment the mass haul view is the grid on which the mass haul line is drawn. The mass haul diagram is a curve in which the abscissas represent the stations of the survey and the ordinates represent the algebraic sum of excavation and embankment quantities from some point of beginning on the profile. An innovative mass haul diagram development for highwayearthwork i akiije department of civil and environmental engineering, university of lagos, lagos, nigeria _____ abstract this paper is on an innovative mass haul diagram development for highway earthwork in an electronics office.
Mass and haul diagram
Using the create mass haul diagram wizard, you can create a mass haul diagram with a single click, accepting the default settings for name, style, display, and balancing options you must have a material list for the drawing before you can create a mass haul diagram. It includes several graphical views, such as gantt chart, resource graph, mass haul diagram and time-distance chart, as well as a comprehensive set of text reports the user is guided by an assistant and views are equipped with online help. To understand the manner in which the mass diagram is used to balance cuts and fills and how haul limit is determined, let’s examine figure 10-10 here the profile of a road, from stations 0 + 00 to 20 + 00, has been plotted above the mass diagram. Mass-haul diagrams (md) have been an essential tool for planning earthwork construction for many applications one of the most common heuristics that is used widely by practicing engineers in this field to balance the md is the “shortest-haul-first” strategy using this heuristic in balancing the md is usually carried out either.

During project development, contractors and design engineers may try to balance the mass haul requirements by considering free haul distances, any overhaul , and the use of borrow pits for embankments and dump sites for extra excavated volumes, based on the economic haul limits and the site conditions.
