Exhibitor & Sponsorship Participation at the Annual Meeting
By Joseph Perello, Exhibit Chair
We would like to thank all of the exhibitors, advertisers and sponsors for participation in the 2005 NJASLA Annual Meeting & Exhibition! Having all of them be a part of our conference at the educational and social events was a benefit to all! Without their participation, our Annual Meeting and Exhibition would not be the success that it continues to be.

Once again, we sold out the entire exhibit floor, and had a record number of exhibit booths! This is a good indication that the exhibitors find our event to be successful, and an important part of their business. We appreciate their time and efforts to provide timely information and innovative features about their products and services to our membership during the Annual Meeting, as well as through our daily business activities.

We hope that this event proved to be a success for the many exhibitors, sponsors and advertisers, and thank you for your continued support and look forward to seeing you at upcoming NJASLA events in 2005. Please stay in touch with us, and visit our web site at www.njasla.org to view our newsletters and information on upcoming events!  Thanks again for your support of NJASLA!

Envirobond Adds Environmentally Friendly Weed Deterrent to Stabilizing Sand
Envirobond Products Corporation recently modified the formula of the company’s stabilizing jointing sand (EnviroSAND™) for paver joints and stabilizing crushed stone (EnviroSTONE™) for flagstone joints. The innovative product line now includes a natural, environmentally friendly weed deterrent additive.

Along with the ability of these new products to remain in place, effectively resisting erosion and traffic, the new natural weed deterrent additive establishes and maintains conditions that do not allow nuisance weeds to grow.

Weed growth is more than just an aesthetic problem for segmental paving systems because if left unchecked, weed growth can lead to loss of structural integrity and other serious deficiencies. Pulling or digging out weeds by hand is labor intensive and time consuming. Attempting to control weed growth by using weed trimmers or lawn mowers can actually stimulate more growth. Herbicides can be used to control weeds. However, spraying weeds with chemicals must be repeated at frequent intervals and safety precautions must be followed. Herbicide spray can also “drift” to areas where it is not wanted and can also be detrimental to the environmental surroundings.

Weed growth is caused by the germination of seeds that find their way into the joints between the paving units and is accelerated when the jointing sand or stone is displaced by soil over time. As more weeds begin to proliferate they eventually push the paving units even further apart and the growth of unwanted vegetation is promoted.

When the joint or crevice remains full, contamination of the joints by soil or debris is prevented. However, even a slight amount of soil contamination provides a growing medium for the weeds to establish their roots. Envirobond has developed a natural additive that works from the bottom up, creating a zone that prevents weed-rooting systems from acquiring the nutrients they require even if germination has begun at the surface level.

The ability of Envirobond products to remain in place, combined with a new natural weed deterrent additive, is an ideal material for wide joint hardscaping.

Landscape contractors, according to Envirobond, will now have a safe and cost effective product designed to resist erosion as well as eliminate persistent, nuisance weeds, which is a primary concern of consumers when considering the purchase of segmental and natural stone paving systems.

Envirobond organic stabilizing sand and stabilizing crushed stone jointing products utilize an environmentally friendly biological binder that has the ability to expand and contract during long-term exposure to the elements without cracking. The “glue” has a re-usable characteristic, which allows it to continually take the new shape of the joint when movement occurs.

The biological bonding mechanism provides an added essential advantage in that the sand and crushed stone retains its plasticity, allowing the paving system materials to remain flexible. The resistance to cracking also improves the structural capacity of paving system and makes it very difficult for soil to accumulate or for weed growth to occur.

Envirobond is currently seeking regional dealers and distributors.

DEP Announces Highlands Rules
Commissioner Bradley M. Campbell today released the Department of Environmental Protection (DEP)'s regulatory standards for the implementation of the Highlands Water Protection and Planning Act. The new regulations, which involve issues including septic density and the permit application review process, take effect immediately.

"The tough environmental rules released today are critical for the protection of New Jersey's Highlands region," said Commissioner Campbell. "These rules also begin a close partnership with the Highlands Council to ensure that the final regulations work in concert with the regional master plan."

The Highlands Act prescribes regulatory standards for the Preservation Area including the protection of open waters and buffers, rare, threatened and endangered species habitat, exemptions, impervious coverage limits and the prohibition of new public water systems. The legislation directs DEP to establish the standards announced today.

The rules establish standards regarding the following:

• Permit Review: The regulations consolidate the review processes required for projects in the Highlands that require multiple permits. DEP will provide the Highlands Council copies of all applications, notify the public of applications and seek public comments.
• Septic Systems: The rules protect existing water quality by establishing septic density requirements based on differences in groundwater quality in heavily forested and disturbed areas.
• Historic and Archaeological Resources: The rules establish procedures for the identification and protection of historic and archaeological resources.
• Unique and Irreplaceable Resources: The rules will help protect parks, reserves vernal habitats and New Jersey Natural Heritage Program-identified ecological communities by regulating activities that impact the communities.

DEP will accept comments regarding its Highlands rules from the Departments of Community Affairs, Agriculture, Transportation and the Highlands Council for a 45-day period prior to rule proposal. DEP will then revise and propose the immediately effective regulations. The final regulatory standards must be adopted within one year.

The New Jersey Highlands is a 1,250-square-mile area in the northwest part of the State, stretching from Phillipsburg in the southwest to Ringwood in the northeast. It lies within portions of seven counties and 87 municipalities. Sixty-four percent of New Jersey residents, about 5.4 million people, receive their water from the Highlands. In addition, the forests and wetlands of the Highlands are important habitat for many species of reptiles, amphibians, mammals and resident and migrating birds.

Interlocking Stone Facts
Design and Installation of Interlocking Concrete Pavers
Part 1 of 8
By Brian Burton
Editor's Note: The market for design and installation of interlocking concrete pavements (ICPs) is growing rapidly as more commercial establishments, institutions and homeowners upgrade their landscaping with pavers. As a result of this trend, the New Jersey Chapter of ASLA is pleased to introduce a new regular feature that will provide up-to-date information regarding the design, installation and maintenance of ICPs prepared by Brian Burton, a ICPI certified Pavement Instructor. Mr. Burtons comment are his alone and not intended to represent product endorsements or recommendations authorized by NJASLA or ASLA.  

Introduction
ICPs are typically manufactured of a size that you can pick up with one hand (e.g. 200 x 100 mm in plan and 60 or 80 mm in thickness).  The applicable US defines a concrete paver as a unit having a surface area of less than 0.065 m2 with an overall length to thickness ratio of less than or equal to four. ICPs are also available in a wide range of patented proprietary shapes that can provide certain advantages in design and performance.

ICPs are manufactured from Portland cement, fine and coarse aggregates, admixtures, pigments and a small amount of water. The ingredients are combined in a low slump concrete mix and processed in automated equipment that applies pressure and vibration to produce a consistent product with a high comprehensive strength.  Pavers are available in a wide variety of colors and special surface finishes.  Taken together the exceptional range of shapes, colors and finishes provide an ability to match the "paver to the project" and customize the appearance of hardscaping installations.

From a performance stand point ICPs provide a "flexible and forgiving" surface which can accommodate constant traffic, severe loads and harsh temperatures without losing their aesthetic appeal, skid resistance or structural integrity.  ICPs are appropriate for any application that requires paving including patios, driveways, pool decks, parking lots, gas stations, sidewalks, roads, ports and airports.

History of Segmental Paving
Segmental paving units have been used by many civilizations to construct roadways for over 5,000 years using natural stone, wooden blocks, clay bricks, and more recently ICPs.  The practice was so well established in Europe that at one time Guilds of Master Paviors held a monopoly on the craft. This time honored medieval tradition included a hierarchy of masters and journeymen who passed the "trade secrets" on to the next generation of apprentice paviors (similar to many construction trades that required tremendous knowledge and skill to accomplish properly).   Some Roman and Aztec roads constructed in this manner are still in serviceable condition and could quite easily be used today except for the fact that they are more valuable as tourist attractions.

ICPs as we know them today were developed in the Netherlands in the late 1950's as a replacement for clay brick streets and they quickly became the pavement of choice for many applications.  In recent years the recognition of the design versatility and durability of ICPs have resulted in growing acceptance of the technology in North American markets.

Design Principles
When installing pavers, the contractor must achieve three kinds of interlock: vertical (achieved by transferring loads to surrounding units through the sand between the joints), rotational (maintained by the thickness of the pavers placed closely together), and horizontal (achieved through the use of laying patterns that disperse forces from vehicles).  (Herringbone patterns offer greater structural capacity and resistance to lateral movement than bond patterns and are recommended for vehicular traffic.) 

Edge restraints, made from plastic, steel, aluminum, and concrete are essential to maintain horizontal interlock while the units are subject to repeated lateral loads.  Compacted dirt against concrete pavers is not an adequate edge restraint.

Design Considerations
Four factors determine pavement thickness and other materials used in construction as follows:

• Environment; as moisture in the soil or base increases, the load bearing capacity decreases.  Extreme temperature variations and freeze\thaw cycles can also effect the pavement. 
• The effect of traffic over the predicted twenty to thirty year pavement life (dependent on the weight and volume of the vehicles).
• Soil sub-grade strength and support has a substantial effect in determining the total thickness of ICPs.  (Uniform compaction of the soil sub-grade to at least 95% is critical to the performance of interlocking concrete pavement systems.)
• The strength and structural support provided by the sub-base, base and all pavement materials used to construct the pavement system.

Concrete pavers have demonstrated reliability, durability and safety. They also create a pavement surface, which can last up to forty years when installed and maintained correctly.  However, like any construction system, they require care in their design, specification and construction.
