To provide a complete environment-maintaining type asphalt melting/attaching phenomenon-blocking agent for paving a road to block a phenomenon that the melting/attaching of the asphalt on the surface of a rolling compaction roller on paving the road to peel off the road surface asphalt for making the pavement as an inferior quality.

This asphalt melting/attaching phenomenon-blocking agent (oil type) is provided by adding a food additive to a chemical substance adaptable to environmental maintenance consisting mainly of an animal and plant-based oil. The agent (oil type) is to utilize the heat of the high temperature asphalt for evaporating alcohol just before the contact of the roller with asphalt by responding with the heat, the surface of the roller is insulated by this vapor heat, then the plant oil cleans the surface by its cleaning effect, and the oils and fats of the animal oil attaches on the surface of the roller and has a synergistic effect for accelerating sliding.
