Sustainably constructed pavement, and methods and apparatus for constructing the same

An apparatus for constructing a pavement project, comprising:

• a hardware processor;
• and
• a memory storing instructions that, when executed by the hardware processor, cause the hardware processor for:
• creating a construction structure for a hot mix asphalt (HMA) pavement according to a pavement project;
• calculating a greenhouse gas (GHG) emission of the HMA pavement;
• performing a sustainable construction on the HMA pavement to modify one or more layers in the HMA pavement to form a sustainably constructed pavement;
• calculating a GHG emission of the sustainably constructed pavement;
• and
• obtaining a carbon reduction by comparing the GHG emissions of the HMA pavement and the sustainably constructed pavement.
