Landscape friendly asphalt pavements include colored pavements which use colored aggregates or pigments and natural colored pavements which make use of the color of natural aggregates such as pebbles.
| Kind | Method | features | | Colored Asphalt Pavements | The method of adding pigments to hot mix asphalt mixtures | Because the mixture uses asphalt, the costs are rather cheap but the colors to be selected are restricted. Available colors are typically steel rust color, green and brown. |
| The method of using colored aggregates as the aggregates of hot mix asphalt mixtures. | The colors are effectuated after the asphalt covering the surface of colored aggregates are removed. Usually, surface is ground just after construction. |
| The method of using decolorized asphalt in stead of ordinary asphalt for hot mix asphalt mixtures | Using decolorized binder and pigment, various colors are available and the resulting colors are vivid. |
| The method of adding pigment to cement milk of semi-flexible pavement | In case the pigment content is small, the color is affected by the color of cement. By using white cement the color become vivid. Occasionally surface grinding is executed just after the construction in order to reveal the surface of aggregates. |
| The method of using colored aggregates for the sprayed aggregates in rolled asphalt pavement. | Besides the coloring, because of excellence at resistance to slip and raveling, these kind of pavements are often applied to carriageway. |
| Natural color pavements | For light traffic, the method of using epoxy resin as binder and natural aggregates such as pebbles or etc.. | Because it uses colors of natural aggregates, tasteful pavements are formed with no aging change of color. In most of cases, this kind of pavements are constructed as water pervious pavements. |
| For vehicle traffic, the method of using de-colorized asphalt as binder. |
| The method of using urethane resin as binder and wood chips as aggregate | Utilizing chips from thinned out woods or waste timbers, realize a pavement with the color of woods and soft foot touch. |

When adopting these kinds of pavements, please pay attention to the followings.
* The prices of aggregates and pigments largely differ depending on the kind.
