It's an asphalt rejuvenator... Heres a brief Internet search blurb on what it does:

Pavement Rejuvenator/Sealer is applied in a one coat application. As pavement ages, essential oils are lost as they volatilize from the pavement leading to cracking and pavement failure. Rejuvenator penetrates the asphalt, restores essential oils, rejuvenates the asphaltic binder and repairs damage within the asphalt matrix. Under heavy traffic, smaller cracks may see some degree of closure.
