Absolutely - the surface asphalt gets exposed as traffic and weathering degrades and removes the surface tar, letting water into the pores and eventually degrading the asphalt. Normally, sealing should be done after 3-6 months of weathering of a new driveway, and about every 2 years after that if water-based sealed, about every 4-8 years if hot asphalt sealed, or about 6-12 years if chip sealed.

Failing to seal it when it get exposed aggregate can cut your driveway life by about 50%, and also make it start breaking up sooner, so you run the risk that your next repave will have to be a total tearout and replace rather than an overlay.
