To help identify future anticipated aggregate demand for upcoming projects, MDOT has recently incorporated various aggregate data into their “2021 Quantity Report”.
However, due to difficulty in determining the actual amount of total material used to construct our roads and bridges (i.e. sign bases and foundations, concrete culverts, precast bridge beams, etc.), the estimated quantities may not be completely accurate but it should help establish a good starting point for tracking trends.
The quantity report lists anticipated aggregate amounts for pay items with various units of payment (tons, syds, cyds). While it is very difficult to convert syds to tons (as the thickness of the pay unit is defined in the plans) it does allow for tracking of these items over time.
Please note that aggregate usage for HMA and Concrete are not provided. Therefore, these estimated quantities will need to be done using the conversion factors as has been done in the past.
