A mass haul diagram where land and rock cuts are hauled to fills Fill construction in 1909 Cut & Fill Software showing cut areas highlighted in red and fill areas shaded in blue. 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 ...
English: A mass haul diagram showing land mass being hauled to land fills and rock mass being hauled to rock fill. The road line station number goes from left to right. This is a simple example of a cut and fill operation in civil engineering earthwo
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.
Almost a week after a horrifying mass shooting left 18 people dead in Lewiston, Maine, questions are mounting over whether the atrocity could have been prevented altogether.. Information continues ...
The first truck weight limits were enacted by four states in 1913, ranging from 18,000 pounds (8,200 kg) in Maine to 28,000 pounds (13,000 kg) in Massachusetts.These laws were passed to protect earth and gravel-surfaced roads from damage caused by the steel and solid rubber wheels of early heavy trucks.
It is the removal of the slope's physical support which provokes this mass wasting event. Thorough wetting is a common cause, which explains why slumping is often associated with heavy rainfall, storm events and earthflows. Rain provides lubrication for the material to slide, and increases the self-mass of the material.
The American Association of State Highway and Transportation Officials (AASHTO) is a standards setting body which publishes specifications, test protocols, and guidelines that are used in highway design and construction throughout the United States.
