PAVING

INTRODUCTION :

Pavements are generally classified by their intended use within a particular landscape
or design context.
Pavement types and structural characteristics are modified by application loading i.e.

• Heavy,
• Medium, Or
• Light Duty

Other criteria to be considered are:

• Sub-grade bearing capacity,

• climate,
• installation, and
• maintenance costs.

LANDSCAPING ELEMENTS
PAVING

INTRODUCTION :

Paving includes the movement of

• Pedestrian And
• Vehicular Pavements

This is typically encountered indoor open spaces or outdoor spaces in

• Residential,
• Urban,
• Institutional,
• Commercial and
• Site Planning Applications.

LANDSCAPING ELEMENTS
PAVEMENT COMPOSITION: PAVING

Pavements are layered composite structures designed to bear pedestrian and

vehicular circulation loads, while providing an even well-drained surface .

The structural layers of pavement commonly consist of a

• prepared sub-grade,
• an aggregate base, and
• a wearing or surface layer.

Sub-grade:
The sub-grade is the soil layer beneath the pavement which bears
• the design load,
• receives infiltration water, and
• is subject to ground water infusion

It may consist of existing site subsoil at the bottom plane of a grading cut, or a controlled
structural fill, placed in compacted lifts. In either event, it is commonly referred to as
"prepared subgrade,"

In most circumstances, the sub-grade is sloped parallel to the finished pavement surface
to insure proper drainage .
LANDSCAPING ELEMENTS
PAVING

Aggregate Base & Sub-base:

The base layer consists of a graded aggregate foundation that transfers the pavement
load to the sub-grade in a controlled radiating manner.

Light duty pavements typically require a single layer of sand or stone dust to serve
both as a setting bed, as well as a structural base.

Heavy-duty pavements or weak sub-grades, usually require an additional layer of

base material, called a ‘Sub-base’, which also consists of a clean but coarser-graded
aggregate layer.

Both aggregate base and sub-base typically extend beyond the pavement edge to
provide lateral support, and to prevent uneven sub-grade loading .

LANDSCAPING ELEMENTS
Flexible Paving PAVING

Flexible unit pavement

applications may range from:

• Cobblestone Service
Roads To
• Light-duty Flagstone
Garden Patios,

Flexible unit paving typically

require edge restraints to
prevent lateral creeping over
time.

Townscape Pavement

Pavements may range from light to heavy duty based upon particular vehicular loading,
but are generally rated as light to medium duty.

LANDSCAPING ELEMENTS
PAVEMENT DESIGN CRITERIA PAVING

Load bearing capacity:

Heavy, medium, and light duty applications generally refer to the type of vehicular and
pedestrian traffic which a pavement must accommodate .

Durability:
Pavement design must accommodate sustained pavement loading as well as
maintenance methods and natural weathering effects .

LANDSCAPING ELEMENTS
PAVEMENT DESIGN CRITERIA PAVING

Safety:
Compiling to the safety standards regarding to
• Texture,
• Joinery,
• Slope,
• Drainage, And
• Associated Site Furnishings
• Pavement Color And
• Pavement Finish are also constrained by reflectivity, glare, and permeability
as they relate to climate setting

Aesthetics:
Patterns and textures should be considered in scale with the larger design to avoid
inappropriate complexity or blandness. Paving patterns can be achieved with a
combination of both flexible and rigid paving systems.
PAVEMENT DESIGN CRITERIA PAVING

Climate:
Hot & Humid:
• Drainage is critical to prevent build-up of mosses and algae, and to account for
intense periods of precipitation .
• Light colors are often used to avoid heat absorption .
• Stable temperatures provide for a wide variety of materials.

Hot & Arid:

• A wide variety of materials are available in this climate zone .
• Materials are typically light in color to avoid heat absorption, and may include
glazed tiles porous finishes due to low humidity and relatively stable temperature
ranges .
PAVEMENT DESIGN CRITERIA PAVING

Climate:
Temperate:
• Darker colors are typical to absorb radiant solar energy.
• Heavy snow regions must account for abrasive clearing practices .
• Mortared unit pavers require heavy maintenance in extensive applications .

Cold:
• Cold areas require similar treatments as the temperate zone, but with more
restrictions.
• Flexible pavements are preferred over rigid and mortared unit pavers .

LANDSCAPING ELEMENTS
Maintenance: PAVING

The actual cost of a pavement must factor in the annual maintenance cost .

Often, a higher initial installation cost may result in a lower annual maintenance
expenditure.

Additionally, the service life of a less expensive installation may be short, requiring
replacement in 8-10 months.

It is prudent to invest in proper site preparation and aggregate base installation, due
to their critical role in maintaining finish surface integrity.

LANDSCAPING ELEMENTS
Maintenance: PAVING

Annual maintenance for pavements typically requires:

• Periodic Coatings,
• Pointing,
• Cleaning And Sealing Of Joints,
• Repair Of Broken Segments Or Settled Areas,
• Re-setting Of Unit Pavers, And
• General Sweeping To Remove Accumulated Fines And Debris .

Unit paving typically requires more attention to maintenance of edges and vegetative
invasion, but is easily repaired .

Monolithic paving commonly requires less annual maintenance than does flexible unit
paving .

LANDSCAPING ELEMENTS
LIGHTING

LANDSCAPING ELEMENTS
Objective of Lighting: Lighting

The purposes of outdoor lighting include :

• Improving the legibility of critical nodes, landmarks, and circulation and activity
zones in the landscape ;

• Facilitating the safe movement of pedestrians and vehicles, promoting a more

secure environment, and minimizing the potential for personal harm and damage
to property; and

• Helping to reveal the salient features of a site at a desired intensity of light in

order to encourage nighttime use.

Lighting

General Design Consideration:

Lighting in the night is important as the designer can decide on:

• Parts of the landscape to be emphasized and
• Parts of the landscape to be hidden.

The desired effect for the designed space can be achieved by means of a combination
of:
• Colour of light
• Mounting height of the fixture
• Direction of the lighting and
• character of the luminaries

LANDSCAPING ELEMENTS
Lighting
General Design Principles:
Clear Lighting Pattern:

A staggered layout of road and pathway light tends to obscure rather than reinforce the
direction of circulation and location of intersection.

Attaining high levels of illumination along circulation routes does not have to be a prime
consideration in outdoor lighting. If a clear and consistent system is provided, low levels
may be adequate for safe circulation.

LANDSCAPING ELEMENTS

General Design Principles:
Placement of Luminaries

Spacing, height, and distribution of luminaires should avoid foliage shadows, provide
uniformity, and vertical surface illumination.

General Design Principles:
Glare:

Glare is a major inhibitor of good visibility and can be produced by any scale of light
fixture, henceforth luminaries must be planned to avoid glare.

LANDSCAPING ELEMENTS
Lighting
General Design Principles:

Atmosphere & Character:

A consistency of design expression can be achieved by identifying the common
elements in a landscape that give it character and then using the similar approaches to
their lighting.

Background:
Background spaces should be illuminated as unobtrusively as possible to meet the
functional needs of safe circulation and protecting people and property.

Whenever possible, these needs should be accommodated with peripheral lighting from
the walkways, signage, entrances, and other elements relevant to the definition of the
space .

Foreground:
Foreground spaces should utilize local lighting which produces maximum focus,
minimum distractions, and no glare .

Foreground spaces or objects may be major elements and should be treated accordingly

LANDSCAPING ELEMENTS
Lighting
General Design Principles:
Illumination of Object:
The direction of the light source is important for perception of three-dimensional objects.

Usually, the best way to illuminate standing objects is with a combination of point
source lighting & Uniform Lighting, both types of lighting .

One source should accentuate shape and form by contrasting the surface with sharp
shadows while the other source provides fill-lighting for details .

Colour Perception:
LANDSCAPING ELEMENTS
Lighting
General Design Principles:

Colour Perception:
Accurate color rendition will aid recognition and improve the perception of outdoor
environments . This is especially important at the pedestrian scale, where the color
contrast of paving and landscape materials is often subtle.

As the general illumination level rises in a given situation, preference usually shifts away
from a warm appearance toward the cool range.
