The goal of mass haul planning is to determine these amounts and the goal of mass haul optimization is to minimize either or both. [ 2 ] Now they can be performed with a computer and specialized software, including optimisation on haul cost and not haul distance (as haul cost is not proportional to haul distance).
The software has a Windows graphical user interface and it includes views such as the Gantt chart, resource graph, mass haul diagram, map view, time distance chart and text reports. [ 9 ] [ 2 ] The time-location method has strengths compared to Gantt charts and traditional scheduling.
TTI HS-20 allowed shorter trucks to have higher weight limits than Formula B. For a 3-axle truck with an axle length of 14 feet (4.3 m), the weight limit increased from 46,500 pounds (21,100 kg) to 54,000 pounds (24,000 kg). [29] TTI HS-20 also failed to address the problem of multiple-span bridges. [28]
