An integrated heating and comb unit and method of mechanized asphalt raking in which a mechanized asphalt comb comprised of a rake attachment and an arm is attached to an engineering vehicle via a terminating end of the arm. The engineering vehicle can control and manipulate the mechanized asphalt comb into a raised inactive position, a lowered active position, and a plurality of positions between the raised inactive position and the lowered active position. When in the lowered active position, the mechanized asphalt comb applies a fixed downward pressure and depth of penetration to the applied surface.
