You must use GPxPatch for that.
The easiest way is :
- create a folder somewhere on your hard drive and name it Tracks (ie: D:\Tracks)
- put the dat files of the tracks you want to use in it
- in GPxPatch go to GPxTrack tab and link your dat file to a slot
- put the jams folder included with your track into the jams folder of the game (ie: C:\Program Files\Infogrames\GP3\GP3JamsH).
Two things about this one :
1- depending on if you're using GP3 or 2000 addon the game is not installed into the same folder : Infogrames for 2000, Microprose for GP3
2- depending on your graphic card, there are two modes the game can play : Software Mode if you have an integrated GC, Hardware Mode if you have an external GC. You'll have to add the relevant jams folder in your game in GP3Jams for Software Mode and GP3JamsH for Hardware Mode.

Ok, so first of all there is a GP3 FAQ where you can find a lot of useful tips to play and mod the game. Read it, especially parts 2, 3 and 4, it's really interesting.
Now, let's assume that you have installed GP3 out of the box. You need to patch it to use the mods made by the community :
official1.13 patch and decrypted-exe (links here) GPxPatch (link here)
Here is a good step by step to install everything. It is for Seven but runs quite the same way for XP (btw GP3 seems to run in a better way on XP and you don't need to set compatibility modes for it).
So now, how to mod the game ?
First have a look in your GP3 directory (C:\Program Files\Microprose\Grand Prix 3). There are several files and folders. One of them is circuits in which you have several .dat files. Those files are the original tracks of the game. Two other folders are Gp3jams and Gp3jamsH that contain the graphics of the tracks and the game. If you go into one of them you will see several folders with a strange name (Bar3jam,...) these folders contain the track graphics.
Now have a look at a track you want to add : you have a zip/rar file that you must uncompress. In it you *should* have a dat file, a jams folder (or two) and a GP3Form file. The latter isn't always there unfortunately but gets useful notes on how to install the track. The main thing is to know where to put the files. The dat one can be put in the circuit folder, but as I've said previously it's better to put all the tracks you add in a separate folder somewhere on your hard drive. For the jams files they MUST be into the Gp3jams or/and Gp3jamsH folders. The best way is to copy the whole jams folder of your rar/zip file into that directories. Be aware that your jams folder doesn't contain another folder (if it's the case, it's this one that you must copy into the directory).
Now how to use your new track in game : in your GP3 directory (C:\Program Files\Microprose\Grand Prix 3) double click on the GPxPatch.exe you have previously installed, that will launch GPxPatch. Go to the GPxTrack tab and go to the track manager and Edit. There you have all the tracks in their running order. To add your track you have to replace an existing one, so click on the button to change the track and go to the folder where your track is. Save it and launch the game by clicking the Start button in GPxPatch.
That's it.

Hello elcorredor when download the track read the file text for instructions is very simple

I agree with holemad. I guess there is no GP3form with the track so that could be difficult to get the right name of the jams folder too.
In last resort you could download Track Editor by Paul Hoad, open the dat file in it and go to the jams section to get that name.

Sorry I don't have that track so can't help you on that. Maybe someone else has it and can help you.
Don't know what's your issue 
Did you put the jams in Gp3jamsH folder and what's the name of the folder they are in ?

There is likely a 2000 season carset available for download. Adding GP3 2000 would require the installation cd.
