The final position of the mass diagram line, above or below the datum line, indicates whether the project was predominately cut or fill. Compute the net earthwork values for each station, applying the appropriate shrink factor net cuts have a positive value, net fills have a negative value the value at the first station origin 0 plot the value of each succeeding station which equals the cumulative value to that point, i. The road line station number goes from left to right. In figure 1010, a 500foot haullimit line has been inserted into the mass diagram curve above and below the lines of. Mass haul diagrams the cumulated volume of earthwork at the.

This is a simple example of a cut and fill operation in civil engineering earthworks. Section 303 earthwork design wyoming department of. This is a quick example of how to estimate cut and fill mass balance for earthwork operations in construction. Mass diagrams or masshaul diagrams are plots of the cumulative volumes of cut and fill along an alignment. In the drawing, snap to the center of the red circle that is above the profile view to place the mass haul diagram. The labeled sections and arrows on the profile show relatively what is to be done to the cuts and fills. The mass haul diagram is created using the data from the xsdata worksheet.

So, the cut and fill process is typically one of the first construction processes to take place on a site. From the cut and fill volumes, adjusted by one of the plans described above, ordinates for the mass diagram are computed from the beginning of the diagram, cut volumes being considered positive and fill volumes negative. The mass haul diagram shows excavation adjusted and embankment quantities from some point of beginning on the profile, considering cut volumes positive and fill volumes negative. A mass haul diagram showing land mass being hauled to land fills and rock mass being hauled to rock fill.

The mass haul view is the grid on which the mass haul line is drawn. Mass haul diagrams to construct the mass haul diagram manually. Chapter 12 volumes and mass haul diagram a practical guide for using inroads xm 19. Swell or shrinkage factors for certain materials source. Basil david daniel mass haul diagram 50000 40000 30000 20000 0 0 0 20000 30000 40000 50000 60000 70000 80000 90000 cumulative volume cubic meter 0 100 200 300 400 500 600 700 800 900 1100 1200 0 1400 chainange m 3 1500. See workflow chart creating cross sections how to create cross sections click on the end area volume icon 1. The total cutminusfill is plotted at each station directly below the profile plot. Since material volume can vary, initial estimates of earthwork and mass. Cut slopes are rarely created greater than a slope of two to one horizontal to vertical dimensions.

Earthworks volumes and masshaul diagram rp71 user guide 5 meaning of individual items is as follows. Grading summary spreadsheet cflhd spreadsheet used to generate the grading summary, mass haul diagram, and miscellaneous summaries. Plot mass haul diagram this diagram is not used by modot. Draw the mass diagram and shade in the areas that will cost money to haul. Correct the volume calculated by shrinkage and swell factors 4. The volume for use is the sum of the peaks and valleys on the diagram. The mass haul line represents the free haul and overhaul volumes in cut and fill conditions along an alignment. Expand all collapse all road standard drawings figure 35. Typically, the mass diagram is plotted below a profile of the route, with the ordinate at any station representing the sum of the volumes of cut and fill up to that station. Chainage where listing of cutfills with possible cutfill changes of summaries is required. Mass haul diagrams upward sloping curves indicate rising left to right indicate a cut downward sloping falling left to right curves occur in a fill section peaks indicate a change from cut to fill and valleys occur when the earthwork changes from fill to cut 7. Earthwork representation guidelines cflhd document providing a guide to the standard procedure for calculating and representing earthwork volumes in the plans.

It does not account for earthwork that could start on either end of the road. The mass diagram is an excellent method of determining waste or borrow volumes and can be adapted to show haul transportation considerations figure 6. The mass haul diagram is displayed, and contains three mass haul regions. 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. The middle axis of the mass haul view is known as the balance line. In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.

Nddot construction conference 2011 east conference. 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. Figure 84 fill area figure 85 cut area figure 86 computation sheet figure 87 curve correction factor figure 88 relationship of balance point and stations figure 89 portion of a mass diagram. A maximum point on the curve represents the end of a cut. Earthwork end area volume end area volume tool performs the traditional endarea volume calculation to compute cut, fill, and net volumes using a series of cross sections extracted along a previously defined alignment 1. Bannister and raymond, 1998 garber 2010 considered the computation of a mass haul diagram after the determination of fill and cut. As shown in the following image, mass haul regions identify station ranges where material is either cut or fill.
