The question is very vague. Common road salt is typically $\ce{NaCl}$ or $\ce{CaCl2}$, both of which are soluble in water. The problem is that "dirt" could be anything, including lots of things that are also soluble in water.
So the idea that washing the mixture with water to remove the solutes would isolate the salt is insufficient. You would need to specify the type of salt you're dealing with and then ask on a chemistry forum how to chemically isolate just that compound.

Youre right, the question is vague. But, that is mainly because I didnt know what salt this was and what materials where in the "dirt". Turns out that it was just common table salt with some sand and small stones. Thanks for your answer.More

Assuming you mean NaCl - the common "salt" (chemists call lots of things salt!).
If you extract the salt by physical means, it's a physics question.
Assuming that the "dirt" is not (or poorly) soluble in water, I would simply dissolve the salt in water, filter the liquid, then recrystallize (by evaporation of the liquid) and weigh the resulting crystals. Not sure if you call that chemistry or physics... it's physical chemistry. It is well described in text books and online - see for example this Scientific American page
Depending on how accurate you want to get, there are a slew of precautions to take. That would be the realm of the chemistry.stackexchange sister site.
