How do you repair cracks in a cement exposed aggregate driveway?

by Karen
I live in central VA where we have times of extreme cold temps in the winter and very hot and humid summers. The driveway has a tint to the concrete which is somewhat tan (not dark). Some cracks are hairline and others are larger. Not sure what to do to fill the cracks to help stop future crack lines. Is there a filler and sealant that I can use to repair and stop future cracks?
