(OP)
Next to me the parking lot of an old apartment building
is being remodeled/repaved. They replaced the top 2 feet
of dirt with crushed rocks on a thick plastic.
I wonder, why ? Any guess ?

Geotextiles are used for many different things in construction. What is the underlying soil like? If it is silty or clayey, they could be using filter fabric to keep the fines (particles under about 1/200") from migrating up into the crushed stone. This plogs up the voids between the particles and messes up the drainage. Bad drainage contributes to weak base conditions, freeze-thaw damage, rutting and the like.
If it was plastic sheet, I haven't the foggiest.

You can learn more about geotextiles and their many uses in road work and other engineering applications. Try searching the web using "geotextile" or visit web pages for companys that make them such as Monsanto, Amoco and 3M.
