NATURALPAVE® XL RESIN PAVEMENT™
GENERAL INFORMATION
NATURALPAVE®
XL RESIN PAVEMENT™
The
significance of the NaturalPAVE® XL Resin Pavement™
technology is clear when the environmental advantages are
considered in: no air pollution or fossil fuel burning required
to heat the product during its manufacturing, transportation
or placement; and no toxic petroleum components to contaminate
land and water. These pavements retain the natural coloration
and texture of the constituent aggregate materials. Additionally,
these light colored solar reflective pavements provide a
cool alternative to black asphalt and its deleterious contributions
to the Urban Heat Island Effect, smog formation, greenhouse
gas emission, global warming and climate change.
Public
interest in environmentally responsible design and construction
continues to motivate increased awareness and implementation
of green construction technology. The U.S. Green Building
Council (USGBC) and its LEED program (Leadership in Energy
& Environmental Design), a Green Building Rating System,
has provided a vitally important standard format for agency
personnel and design consultants who specify the materials
for new construction and remodeling projects. Many facilities
are now being constructed according to these standards.
The LEED rating system has set the bar high and NaturalPAVE
XL Resin Pavement is ideally suited for green building pavement
requirements.
COOL
PAVEMENT
When different pavements are tested with infrared thermometers
to evaluate their comparative surface temperatures, NaturalPAVE®
XL Resin Pavement™ typically tests similar in temperature
to light colored concrete, while adjacent asphalt pavements
are far hotter. This temperature difference is a health
and comfort issue adjacent to residential areas, offices,
theme parks, schools, and other public facilities. Heat
absorbent asphalt pavements are gaining increasing notoriety
for their contribution to Urban Heat Island problems, increased
air conditioning and energy demand, increased smog formation,
greenhouse gas emission, global warming and climate change.

XL RESIN PAVEMENT™
THE
SIGNIFICANCE OF THE NATURALPAVE® XL RESIN PAVEMENT™
TECHNOLOGY IS CLEAR WHEN THE ENVIRONMENTAL ADVANTAGES ARE
CONSIDERED IN: NO AIR POLLUTION OR FOSSIL FUEL BURNING REQUIRED
TO HEAT THE PRODUCT DURING ITS MANUFACTURING, TRANSPORTATION
OR PLACEMENT; AND NO TOXIC PETROLEUM COMPONENTS TO CONTAMINATE
LAND AND WATER. THESE PAVEMENTS RETAIN THE NATURAL COLORATION
AND TEXTURE OF THE CONSTITUENT AGGREGATE MATERIALS. ADDITIONALLY,
THESE LIGHT COLORED SOLAR REFLECTIVE PAVEMENTS PROVIDE A
COOL ALTERNATIVE TO BLACK ASPHALT AND ITS DELETERIOUS CONTRIBUTIONS
TO THE URBAN HEAT ISLAND EFFECT, SMOG FORMATION, GREENHOUSE
GAS EMISSION, GLOBAL WARMING AND CLIMATE CHANGE.
THERMAL
CONDUCTIVITY
THE
THERMAL CONDUCTIVITY OF A PAVEMENT MATERIAL IS ALSO RELEVANT
TO ITS EFFECTIVENESS AS A COOL PAVEMENT. A PAVEMENT THAT
HAS HIGH THERMAL CONDUCTIVITY, SUCH AS ASPHALT, IS GOING
TO RAPIDLY TAKE ON THE SOLAR ENERGY AND TRANSMIT HEAT THROUGH
THE PAVEMENT INTO THE BASE COURSE MATERIALS AND SUBGRADE
SOILS BELOW THE PAVEMENT. AS INDICATED BY TESTING AT THE
ASU SMART MATERIALS TESTING FACILITY, BOTH ASPHALT AND CONCRETE
PAVMENT MATERIALS CONDUCT HEAT MORE RAPIDLY THAN NATURALPAVE
XL RESIN PAVEMENT. IN COMBINATION WITH HIGH SOLAR REFLECTANCE,
THIS ADVANTAGE IN THERMAL RESISTANCE MAKES NATURALPAVE XL
RESIN PAVEMENT THE STANDARD FOR COOL PAVEMENT TECHNOLOGY.
OVERLAYING
ASPHALT
Whether
it’s air or water quality protection, the comfort
of a cool pavement surfacing, or a matter of simple natural
aesthetics, NaturalPAVE® XL Resin Pavement™ can
be utilized to cover up existing asphalt pavement as an
“overlay” in similar manner as additional layers
of asphalt are placed on top of older asphalt pavements.
As the environmental and aesthetic rationale for overlaying
asphalt with a more appropriate pavement surfacing gains
further recognition, the tried and proven NaturalPAVE XL
Resin Pavement technology will be the obvious choice.
Pictured above is paving
work in progress at a recent project in Washington, D.C.
The surface of the existing asphalt pavement was milled
down so that road surface grades could be maintained once
the NaturalPAVE XL Resin Pavement overlay was installed.
The NaturalPAVE XL Resin Pavement mixture was placed with
a standard asphalt paving machine and asphalt compaction
equipment
