A properly designed pervious concrete pavement system can reduce the environmental impact often associated with development. This overview discusses the hydrologic design of pervious concrete, both passive and active mitigation systems and the important consideration in design for storms. The article includes a link to a publication on pervious paving design as well.

This special report describes the accelerated pavement testing of ultra-thin whitetopping (UTW) undertaken by the Federal Highway Administration at their accelerated loading facility (ALF) in McLean, Virginia. The UTW pavement sections were placed in 1998 atop existing asphalt sections that had been previously loaded by the ALF. The eight pavement sections were loaded by the facility, and five of the eight lanes showed little or no distress as a result. Conclusions indicate that the load carrying capacity of UTW is sufficient for its intended uses, including streets, local roadways, general aviation pavements, bus lanes, turning lanes, and ramps.

This 3 page article reviewed the U.S. and Canadian Green Building Councils LEED® versions for new construction. It provides the why behind LEED®, i.e. a project checklist used voluntarily that aims to reduce construction, energy and water-related operating costs while reducing environmental impacts. It also explains how permeable interlocking concrete pavement can contribute LEED® points through Sustainable Sites (SS) via stormwater management. In addition SS points can be earned through reducing urban heat island on parking lots and roofs, by reducing construction waste, reusing pavers and by using recycled materials, using materials made from within the region as well as proposing innovative design and using durable materials. Applications: Stormwater Design and Management, Heat Island Reduction, Recycling, Regional Manufacturing, Waste Management.

This 4 page article continues from the May issue on how LEED® credits can be earned under the five principal categories. It details how points Sustainable Sites (SS) can be earned through heat island effect both in non roof and roof, material and resources, by reducing construction waste, resource reuse, by using recycled materials, using materials manufactured within the region as well as incorporating innovative improvements in building materials and design and durable materials. Applications: Heat Island Effect, Materials and Resources, Construction Waste Management, Resource Reuse, Recycled Content, Regional Materials, Innovation and Design Process, Durable Materials.

Recommendations for successful performance of pervious concrete pavements under the various freeze-thaw conditions have been provided. There is limited experience of performance of pervious concrete pavements in hard wet freeze areas. Therefore, in such areas utmost care must be taken. Pervious pavements should be placed by an experienced installer and the pavement structure and surrounding details should be designed to accommodate the anticipated water flow and drainage requirements.

The large void content designed into this specialty concrete allows water to pass through rapidly, minimizing runoff and recharging groundwater supplies. Also known as permeable concrete, porous concrete, gap-graded concrete, no-fines concrete, and enhanced porosity concrete, pervious concrete can be used in a wide range of applications, although its primary use is in pavements.

While pervious concrete pavement has been around for more than 20 years, it has only recently garnered much attention due to increasingly stringent stormwater management guidelines that now position the product as a sustainable building material. Pervious concrete provides the potential for environmentally responsible site use and lowered construction costs in projects ranging from a simple sidewalks, driveways and patios, to major pedestrian plazas and full-blown multi-acre parking lots for national commercial big box builders.

The process included the use of full-depth reclamation (FDR) with cement for the base and ultra-thin whitetoppping (UTW) for the surface. Pavement design called for 3-1/2 inches of UTW with control joints sawn in a four-foot grid over eight inches of an FDR base. Tests performed after construction showed the cement-stabilized FDR base with a 28-day compressive strength of 320 psi and a 28-day concrete compressive strength of 5,250 psi. After a year of traffic, the reconstructed street is performing well, and the city is pleased with the results.

Concrete is the most widely used building material on earth. It has a 2, 000 year track record ofhelping build the Roman Empire to building today's modern societies. As a result ofits versatility, beauty, strength,·and durability, concrete is used in most types ofconstruction, including homes, buildings, roads, bridges, airports, subways, and water resource structures. And with today's heightened awareness and demandfor sustainable construction, concrete performs well when compared to other building materials. Concrete is a sustainable building material due to its many eco{riendly features. The production ofconcrete is resource efficient and the ingredients require little processing. Most materials for concrete are acquired and manufactured locally which minimizes transportation energy. Concrete building systems combine insulation with high thermal mass and low air infiltration to make homes and buildings more energy efficient. Concrete has a long service life for buildings and transportation infrastructure, thereby increasing the period between reconstruction, repair, and maintenance and the associated environmental impact. Concrete, when used as pavement or exterior cladding, helps minimize the urban heat island effect, thus reducing the energy required to heat and cool our homes and buildings. Concrete incorporates recycled industrial byproducts such as fly ash, slag, and silica fume that helps reduce embodied energy, carbon footprint, and waste.

This report presents the results of solar reflectance testing on 135 concrete specimens from 45 concrete mixes, representing a broad range of concretes. This testing determined which combinations of concrete constituents meet the solar reflectance index requirements in the Leadership in Energy and Environmental Design for New Construction (LEED-NC) Sustainable Sites credit for reducing the heat island effect. All concretes in this study had average solar reflectances of at least 0.30 (corresponding to an SRI of at least 29), and therefore meet the requirements of LEED-NC SS 7.1. These concretes also meet the requirements for steep-sloped roofs in LEED-NC SS 7.2. The lowest solar reflectances were from concretes composed of dark gray fly ash. The solar reflectance of the cement had more effect on the solar reflectance of the concrete than any other constituent material. The solar reflectance of the supplementary cementitious material had the second greatest effect.
