In very wet years over here in Holland, they sometimes had to harvest the corn silage over frozen ground because conditions were too muddy during the autumn. The corn that was chopped and silo'd when frozen, was fed to the cows in early summer at temperatures of +22°C and still frozen !!
I have seen a wheel loader spreading piled dirt in the spring, which was excavated and piled in the winter. In the hot spring, the pile wasnt defrosted yet.
because you want to elevate the road bed about 4 feet, just think of how long it would take to defrost the soil if it was frozen 4 feet deep.
If you cant afford to loose time and start digging during frost season, i would at least try to dig off the frozen layer first and put that aside, then elevate with non frozen subsoil and finally put the frozen chunks back on top of the non- frozen soil. If you dont, it will take a long, long time before the soil defrosts.
