The water doesn't make things transparent it just changed the amount of light that the object reflects, the wet area absorbs more light rather than reflecting it making the wet area appear darker. The use of a wet paper towel just allows you to see what happens.

No I think the sunlight only penetrates the top layer of the pavement. Like a big stack of paper won't become transparent when you put water on top.
This video shows how and why things turn darker when they are wet. It is a simple experiment with a simple answer, but it may not be what you think.(more)(less)
it's a mazing thing around us

Reply to #4: So if you dug a hole and looked at the other side of the pavement, you'd see the sunlight slipping through! Amazing.

Reply to #2: Just watch the video again. ... The water decreases the reflectivity on the upper side of the pavement (the side where you stand on).

Reply to #1: Yes it is, increased transmission is decreased reflectivity. Brightness = reflected light.

how does that apply to the pavement??

That's no answer.
