What equipment/material/knowledge is needed to visually fix a garage ramp

construction

On the left is the actual state of a garage ramp. I'd like to rectify it visually so that it looks as on the right. What knowledge/tools do I need to achieve such?

##Edit

Following the answer received, I believe my question may not be clear enough. The image on the left, illustrate some visual defects, where it makes it clear that the ramp was "patched" at one point in time and hence doesn't maintain the same visual consistency it had from the top (see half top is correct).

Please ignore the debris, materials, etc. I am specifically asking for the surface itself, do I need to break it and redo or is there a way I can apply cement or something on the top to rectify the surface so that it's uniform and visually correct?

I'd start by pressure washing the ramp with a light degreaser/driveway cleaner to see what defects remained. Some of the colorization seems to be surface stains. Then, you could epoxy-paint or stain it to at least get a uniform look, though that wont help if there are large cracks, voids or holes. Problem with any coating is that you will be driving on it, so it will be hard to maintain the "clean" uniform look (tire marks) compared to the walking ramp on the right picture.
