Here is an example of GBE calculation adopted from Piryonesi (2019). [1] This example belongs to a road in the LTPP database. This road is made of the following layers: subbase, base, and three layers of hot mixed asphalt concrete.
The output of a petrochemicals plant is an input to an asphalt plant, a cosmetics factory and a plastics factory. Output for the end buyer : Factory output goes to the consumer via a service business such as a retailer or an asphalt paving company. Resource allocation : Resource allocation is assigning inputs to produce output. The aim is to ...

Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.
FWD data is most often used to calculate stiffness-related parameters of a pavement structure. The process of calculating the elastic moduli of individual layers in a multi-layer system (e.g. asphalt concrete on top of a base course on top of the subgrade) based on surface deflections is known as "backcalculation", as there is no closed-form solution.
