=={{SpanID|620.7.1}}620.7.1 Standardization of Application (MUTCD Section 3H.01)==
'''Guidance. '''Colored pavements are not currently used on MoDOT facilities. The Highway Safety and Traffic Division should be contacted for guidance when considering the use of colored pavements.

'''Support. '''Colored pavements consist of differently-colored road paving materials, such as colored asphalt or concrete. Other surface treatments can be applied to the surface of a road, island, or area outside the traveled way to simulate a colored pavement. 

If non-retroreflective colored pavement is used as a purely aesthetic surface treatment (see  [[#620.7.3|EPG 620.7.3]]) within the provisions of EPG 620.7 and are not intended to communicate regulations, warnings, guidance, or other information to road users, the colored pavement is not considered to be a traffic control device, even if it is located between the lines of a crosswalk.

'''Standard. '''If colored pavement is used within the traveled way, on flush or raised islands, or on shoulders to communicate regulations, warnings, guidance, or other information to road users, or if retroreflectivity is used, the colored pavement shall be considered a traffic control device and shall be limited to the colors and applications specified in EPG 620.7.

Except as provided in the first Option paragraph of [[#620.7.7|EPG 620.7.7]], colored pavement shall only be used if the corresponding regulations, warnings, or guidance are applicable at all times.

'''Guidance. '''Colored pavements used as traffic control devices should only be used where the color pavement contrasts significantly with adjoining paved areas.

'''Support. '''The chromaticity coordinates that define the ranges of acceptable colors for traffic control devices are found in the Appendix to Subpart F of 23 CFR 655.

'''Standard. '''If used, colored pavement shall only be used to supplement other markings as provided in the EPG.

'''Support. '''Longitudinal pavement markings, crosswalks, pavement marking symbols, and elongated route markers are not considered colored pavements.

=={{SpanID|620.7.2}}620.7.2 Materials (MUTCD Section 3H.02)==

'''Option. '''Colored pavements may be either retroreflective or non-retroreflective, in accordance with the provisions of EPG 620.7 for specific applications. 

'''Guidance. '''If surface treatments are applied to the surface of a road, island, or other area outside the traveled way to simulate a colored pavement, pavement marking materials should be selected that will minimize loss of traction for road users (see the second paragraph of  [[620.1 General (MUTCD Chapter 3A)#620.1.2|EPG 620.1.2]]).

'''Support. '''Providing for retroreflectivity, such as incorporating glass beads, can affect the skid resistance of pavement markings. 

Installation of colored pavement to one lane or an area or portion of a multi-lane traveled way can create differentials in skid resistance values between the areas of colored pavement and non-colored pavement that might be unexpected by the road user.

[[File:Figure 620.7.3 Aesthetic Treatments for Transverse Crosswalks.png|thumb|center|800px|alt=A crosswalk is shown. The example crosswalk materials shown are brick, stone, and paver. The example geometries shown are lattice, mesh, grid, and polygon. The example colors shown are red, brown, tan, and clay.
|'''Figure 620.7.3''' Aesthetic Treatments for Transverse Crosswalks]]


'''Support. '''Aesthetic surface treatments are sometimes used between the transverse lines within a crosswalk, in islands, in medians, in shoulders, within sidewalk extensions designated by pavement markings, or in other areas outside of the traveled way.

Common examples of materials used as aesthetic surface treatments include brick, paving bricks, paving stones, or other materials designed to simulate such paving. Some examples of geometries for aesthetic surface treatments include honeycomb, lattice, mesh, grid, and regular polygon patterns.

Surfaces with individual units laid out of plane and those that are heavily-textured, rough, or chamfered, could increase rolling resistance and subject pedestrians who use wheelchairs to the effects of vibration; it is desirable to minimize surface discontinuities. 

Common examples of colors for aesthetic surface treatments incorporated into the material or geometry are brick red, rust, brown, burgundy, clay, tan, or similar earth-tone equivalents (see [[#fig3h1|Figure 620.7.3]]).

'''Standard. '''Aesthetic surface treatments shall not interfere with traffic control devices.

Aesthetic surface treatments shall not be of a surface that can confuse pedestrians with vision disabilities that rely on tactile treatments or cues for navigation.

Colors used for aesthetic surface treatments shall be outside the chromaticity coordinates that define the ranges of acceptable colors for traffic control devices.

Patterns that constitute a purely aesthetic surface treatment shall be devoid of advertising and shall not contain elements of retroreflectivity.

Patterns that constitute a purely aesthetic surface treatment for the interior area of a crosswalk shall not be designed to encourage road users to remain in the crosswalk, engage or interact with the pattern, or otherwise inhibit users from crossing the street in a safe and efficient manner.

'''Guidance. '''Aesthetic surface treatments should not use colors or patterns that degrade the contrast of markings used to delineate an area, or that might be mistaken by road users as a traffic control application. 

To provide contrast, a gap of at least one-half the width of the white transverse line used to establish the crosswalk, but not less than 6 inches, should be used between the white crosswalk lines and the aesthetic surface treatment, such as unmarked pavement or a black contrast line (see  [[620.1 General (MUTCD Chapter 3A)#620.1.3|EPG 620.1.3]]).

To provide contrast, a gap of at least the width of the longitudinal line used to establish the area should be used between the longitudinal line and the aesthetic surface treatment, such as unmarked pavement or a black contrast line (see  [[620.1 General (MUTCD Chapter 3A)#620.1.3|EPG 620.1.3]]). If the longitudinal line is a double line, the gap should be at least the width of one of the lines that makes up the double line.

Aesthetic surface treatments should not contain pictographs, illustrations, or symbols.

|'''Figure 620.7.4''' Examples of Yellow-Colored Pavement Applications]]

'''Support. '''Yellow-colored pavement is used to enhance the conspicuity of areas separating traffic traveling in opposite directions of travel and the left-hand edge of the roadway. 

'''Standard. '''If used, yellow-colored pavement shall be limited to:
::A. Flush or raised median islands separating traffic flows in opposite directions, 
::B. Left-hand shoulders of divided highways, and
::C. Left-hand shoulders of one-way streets or ramps.

Yellow-colored pavement shall not be incorporated into elements of the roadway that function as two-way left-turn lanes. 

Yellow-colored pavement shall not be used on channelizing islands where traffic travels in the same general direction on both sides.

'''Option. '''Yellow-colored pavement may be installed for the entire length of the roadway, island, or shoulder, or for only a portion or portions of the roadway, island, or shoulder. 

'''Support. '''An example of an application of yellow-colored pavement is shown in [[#fig3h2|Figure 620.7.4]].

|'''Figure 620.7.5''' Examples of White-Colored Pavement Applications]]


'''Support. '''White-colored pavement is used to enhance the conspicuity of areas separating traffic traveling in the same direction of travel and the right-hand edge of the roadway'''. '''

'''Standard. '''If used, white-colored pavement shall be limited to:
::A. Flush or raised channelizing islands where traffic passes on both sides in the same general direction, 
::B. Right-hand shoulders, 
::C. Exit gore areas, and
::D. Entrance gore areas.

'''Guidance. '''When used on right-hand shoulders, white-colored pavement should be limited to areas not intended for use by motor vehicle traffic except those shoulders designated for emergency use.

'''Option. '''White-colored pavement may be installed for the entire length of the roadway, island, or shoulder, or for only a portion or portions of the roadway, island, or shoulder. 

White-colored pavement may be used instead of chevron markings (see [[620.2 Pavement and Curb Markings (MUTCD Chapter 3B)#620.2.15|EPG 620.2.15]] and [[620.2 Pavement and Curb Markings (MUTCD Chapter 3B)#620.2.24|620.2.24]]) in neutral areas.

=={{SpanID|620.7.6}}620.7.6 Green-Colored Pavement for Bicycle Facilities (MUTCD Section 3H.06)  ==

'''Support. '''Green-colored pavement is used to enhance the conspicuity of locations where bicyclists are expected to operate, and areas where bicyclists and other traffic might have potentially conflicting, weaving, or crossing movements. Green-colored pavement is also used to enhance the conspicuity of word, symbol, and/or arrow pavement markings when these markings are used in certain bicycle facilities.

MoDOT does not typically install or maintain green-colored pavement for bicycle facilities. 

'''Guidance. '''If green-colored pavement is installed on a MoDOT route, an agreement should be in place with the local agency that will maintain the green-colored pavement. 

'''Standard. '''If used, green-colored pavement shall be limited to the applications described in Chapter 9E of the MUTCD.

Green-colored pavement shall not be:
::A. Incorporated into electric-vehicle parking stations or parking stalls,
::B. Incorporated into crosswalks (see [[620.3 Crosswalk Markings (MUTCD Chapter 3C)|EPG 620.3]]),
::C. Used as a background for shared-lane markings (see [[914.5 Markings (MUTCD Chapter 9E)#914.5.09|EPG 914.5.9]]), or
::D. Used instead of the required markings for bicycle facilities (see [[914.5 Markings (MUTCD Chapter 9E)#914.5|EPG 914.5]]).

If used, the pattern of the green-colored pavement supplementing dotted extension lines shall match the pattern of the dotted lines, thus filling in only the areas that are directly between a pair of dotted line segments. If used, the pattern of the green-colored pavement supplementing a dotted longitudinal line, which defines a bicycle lane (see the third Guidance paragraph of [[914.5 Markings (MUTCD Chapter 9E)#914.5.2|EPG 914.5.2]]), shall match the pattern of the dotted line, thus filling in only the areas that are directly between a line segment and the curb, or, in the absence of a curb, the edge of the roadway.

'''Guidance. '''If green-colored pavement is used within separated bicycle lanes on an independent alignment, it should be used only at the entrances to those facilities from roadways open to public travel or at conflict, weaving, or crossing locations.

If green-colored pavement is used within shared-use paths, it should be used only where pedestrian and bicyclist movements are separated and for only a portion (or portions) of the path designated for bicyclist use.

'''Option. '''Green-colored pavement may be installed for the entire length of a bicycle lane or bicycle lane extension or for only a portion (or portions) of the bicycle lane or bicycle lane extension.

Green-colored pavement may be installed for the entire length of a physically-separated bikeway within the roadway or for only a portion (or portions) of the physically-separated bikeway within the roadway.

'''Guidance. '''Appropriate regulatory (see MUTCD Chapter 9B) or guide signing (see MUTCD Chapter 9D) should be installed to provide related information to the presence of the colored pavement.

=={{SpanID|620.7.7}}620.7.7 Red-Colored Pavement for Public Transit Systems (MUTCD Section 3H.07)  ==

'''Support. '''Red-colored pavement is used to enhance the conspicuity of locations, station stops, or travel lanes in the roadway exclusively reserved for vehicles of public transit systems or multi-modal facilities where public transit is the primary mode. These public transit vehicles include buses, streetcars, trolleys, light-rail trains, and rapid transit fleets. 

'''Option. '''Red-colored pavement may be used where engineering judgment determines that one or more of the following conditions are expected to result from its application:
::A. Increased travel speeds will be expected by the public transport vehicle after an exclusive lane or facility is provided, 
::B. Reduced overall service time through the corridor will be expected by the public transport vehicle,  
::C. Decreased rates of illegal parking or occupation of the transit or multi-mode lane or facility will be expected. 

'''Standard. '''If used, red-colored pavement shall be applied only in lanes, areas, or locations where general-purpose traffic is not allowed to use, queue, wait, idle, or otherwise occupy the lane, area, or location where red-colored pavement is used.

Red-colored pavement shall be installed for the full width of the lane.

'''Option.''' Red-colored pavement may be used for full-time or part-time operations.

Red-colored pavement may be installed for the entire length of a restricted lane or for only a portion (or portions) of the restricted lane.

Red-colored pavement may be installed in a broken (intermittent) or dotted pattern where entrance into the transit lane is permitted by general traffic, for example where general traffic is allowed in a transit lane in advance of a turn.

'''Standard. '''Regulatory signs (see  [[903.2 Regulatory Signs and Barricades (MUTCD Chapter 2B)#903.2.2|EPG 903.2.2]] and MUTCD Section 2G.03) shall be used to establish the allowable use of the lane, area, or location. Regulatory signs shall also be used when it is determined that other vehicles will be allowed to enter the lane to turn or bypass queues.

'''Guidance. '''If red-colored pavement is used on public transit facilities separated from the roadway or on facilities on an independent alignment, it should be used only at the entrances to those facilities from roadways open to public travel.

'''Support. '''Examples of applications of red-colored pavement are shown in [[#fig3h5|Figure 620.7.7]].
