Road Maker caters for the needs of design professionals and contractors. Data can be extracted from a DTM (Digital terrain Model) survey using MODEL MAKER and can be exported to ROAD MAKER or data can be entered manually.
The vertical alignment and road cross-sectional profile is defined using easy-to-use built-in functions. Bulk earthwork volumes can be calculated between a ground cross-section group and the design profile or between any two ground cross-section groups. Detailed volumes van also be calculated for e.g. layers, topsoil etc. Final cross-section and long-section drawings can be plotted directly to a plotter, plot file or various CAD data exchange or ASCII formats like DWG, DXF, Trimble Exchange, Trimble RXL, XML, SurveyPro etc.
Complete setting-out information can be obtained for setting out the design on site, e.g. layer profiles and batter boards. The design profile or ground cross-sections can be converted into DTM format for further manipulation with MODEL MAKER.

ROAD MAKER MODULES
Why modules? – So that each user can customize his own package and thus saving cost by not having to buy un necessary/unused software functionality.
Required Modules: (3)
Using this module multiple chainage cross-sections may be imported from various file formats or entered manually. A long-section could be loaded or extracted from the cross-sections. Only one section profile can be viewed at any one time.
Required Modules: 1
Up to 8 cross-section and long-section profile groups may be loaded. Any one or all of these groups may then be plotted. Earthworks volume calculations may be done between any two groups. This module is also required with Module 3 if one would like to balance the Cut and Fill Volumes over a length of road.
Required Modules: 1, (2)
This module provides the user with user-friendly and very flexible road design functions. The vertical alignment design may be done directly on screen or it may be entered from external design results. It allows for non-symmetrical vertical curves and the checking of design limits. The cross-sectional profile is defined using the most advanced techniques in manipulating individual components independent from others for example :- road width and batter slope changes. An extensive verge design function supplements the basic design profile. Variable drains, batter parameters and topsoil stripping may be specified. Calculation results include volume calculations for mass-earthworks, foundation layers, layers on shoulders, setting-out data and conversion of the final profile to DTM format. NEW: It is now also possible to import a DTM of the original ground surface as well as a network of road alignment strings (Module 1,2 & 11 from model maker is required) and graphically design a network of roads at the same time. All intersection levels are recorded and used by the vertical alignment for each road. This process eliminates a lot of the user error when designing road crossings and intersections.
Required Modules: 1
The offsets and elevations forming the ground cross section profile at each peg distance may be edited on the graphic screen. This may typically be used to create a rehabilitation profile for quarries or mine dumps or for the definition of a benching profile in road cuttings.
Required Modules: 1,3
Two single carriageway profiles may be defined independently with an offset between each other to define a dual carriageway road. All the functions for a single carriageway are used and each carriageway may have it’s own vertical alignment. Cross-section drawings will show both carriageways. This module can also be successfully used to design complex parking areas next to single carriageways.

After the calculation of mass earthworks volumes the result may be used to plot a mass haul diagram. The diagram is plotted in the form of a long section with user definable vertical and horizontal scales. Additional borrow and spoil values can also be applied and compaction and bulking is also carted for.

The horizontal and vertical alignment design is used to determine various design criteria. This module has 3 components – Calculate the RISE/FALL and curvature factors as required by HDM (Highway design and maintenance) document for the construction of main roads. Calculate horizontal and vertical alignment sight distances in both directions along the road. Calculate the 85 percentile speed profile in both directions to determine climbing lanes.
