  • Cementitious porous pavement in stormwater quality control: pH and alkalinity elevation

    A certain level of alkalinity acts as a buffer and maintains the pH value in a stable range in water bodies. With rapid urban development, more and more acidic pollutants flow to watersheds with runoff and drop alkalinity to a very low level and ultimately degrade the water environment. Cementitious porous pavement is an effective tool for stormwater acidic neutralization. When stormwater ...

  • Army Corps Chooses Porous Pavement System for Rock Island Project

    Leaders at the Army Corps of Engineers prepared to construct a parking lot at their Rock Island Arsenal site in Rock Island, Illinois. After considering all of their options, they enlisted the help of the General Asphalt Construction Company and LPS Pavement to install an environmentally friendly pavement system that remains fully ready for active ...

  • Dual-function growth medium and structural soil for use as porous pavement

    Permeable grass-covered surfaces can reduce the quantity of storm water runoff and filter out potentially harmful chemicals. The objective of this study was to develop permeable structural soils that sustained healthy turf growth and filtered heavy metals from contaminated pavement runoff. The basic soil medium was a 50:50 mixture (v/v) of expanded shale (ExSh) and quartz sand (QS). The ExSh ...

  • Gravelpave2 vs Concrete Pavements

    Porosity As an alternative to traditional impervious pavements like concrete and asphalt, the runoff volumes generated by the Gravelpave2 surface will be greatly reduced. Indeed, as much as 35% of the compacted porous base course and porous wearing course pavement section is air (void), which will be the first area for stormwater to occupy as it falls upon the surface. Assuming a ...

  • Effects of a porous pavement with reservoir structure on runoff water: water quality and fate of heavy metals

    ABSTRACTThe present paper reports a study conducted to compare pollutant loading of runoff waters either collected at the outlet of a porous pavement with reservoir structure or coming from a nearby catchment drained by a conventional separate sewarage system, on the experimental site of Rezé (France). The mean pollutant loads measured at the reservoir structure appear notably lower than those ...

  • Simulation of heavy metal pollution from stormwater infiltration through a porous pavement with reservoir structure

    ABSTRACTA laboratory experiment was set up to examine the ability of porous asphalt to retain metallic pollution. The results obtained confirm the retention of metals (Pb, Cu, Cd, Zn) by clogging particles, and a decrease in lead concentration can be observed in infiltrated runoff water. Moreover, the simulation of heavy metal transfer into the soil was carried out using the mathematical model ...

  • Permeable paver design compared to impervious pavement standards

    Porous pavements by their very nature are designed to move water through their cross section - vertically and horizontally, without loss of structural integrity. This is in direct opposition to design training and construction materials and methods developed since the early 1900’s, where totally impervious pavement sections were the supreme objective. Must all pavements be constructed to ...

  • Evaluation of Performance of Permeable Interlocking Block Pavements

    Drainable or permeable pavement systems are rapidly gaining popularity in Japan because of the high level of precipitation and the growing need for measures against the deteriorating road environment. In the field of interlocking block pavements, highly-porous permeable systems are expected to be increasingly used for constructing walkways and other facilities. However, various issues remain to ...

  • When Are Plain Gravel Surfaces Really Porous?

    Invisible Structures, Inc. makes reinforcement structures for two forms of porous pavements – Grasspave2 and Gravelpave2. When project demands call for porous pavement, and construction budgets are tight, someone will usually suggest that plain old gravel will work just as well, and cost less money. Is this suggestion true? Historical Gravel Pavements are not Porous ...

  • The effect of permeable pavement on water quality and quantity

    ABSTRACT Three studies have been conducted by NC State University faculty since 1999 regarding permeable pavement. A test of long term hydrologic conductivity was conducted on three lots in Eastern NC. The initial hydrologic infiltration rate study showed a significant reduction in surface runoff. The Curve Numbers at the Kinston, Wilmington, and Swansboro sites were 79, 89, and 45 ...

  • Hydraulic and treatment performance of pervious pavements under variable drying and wetting regimes

    Pervious pavements are an effective stormwater treatment technology. However, their performance under variable drying and wetting conditions have yet to be tested, particularly under a continuous time scale. This paper reports on the clogging behaviour and pollutant removal efficiency of three pervious pavement types over 26 accelerated years. These pavements were monolithic porous asphalt (PA), ...

  • Water quality and quantity assessment of pervious pavements performance in experimental car park areas

    Pervious pavements have become one of the most used sustainable urban drainage system (SUDS) techniques in car parks. This research paper presents the results of monitoring water quality from several experimental car park areas designed and constructed in Spain with bays made of interlocking concrete block pavement, porous asphalt, polymer-modified porous concrete and reinforced grass with ...

  • Miami Art Museum uses Porous Gravel Paving to Mitigate Stormwater and Add Beauty

    The Pérez Art Museum Miami (PAMM) installed Gravelpave2 for stormwater mitigation, ADA accessibility, tactile response, and visual and sound aesthetics.  Imagine arriving at an art museum and having your sensory perception adjusted in the parking lot, even before entering the building.  That’s exactly what the architects for the new Pérez Art Museum Miami (PAMM) ...

  • Cold weather performance of grasspave2 and gravelpave2

    Grasspave2 and Gravelpave2 have many advantages for use in cold climates over hard surface impermeable pavements, such as asphalt and concrete. Porous Paving is more resistant to freezing. Damp underlying soils hold heat beneath the paved surface (Backstrom 2000). Porous pavement exhibits increased speed in thawing compared to conventional pavements, due to the ability of melted water to flow ...

  • Fire access case study summary 1

    Environmental regulations that control and limit storm water runoff, reduce impervious surfaces, and increase green space have resulted in the growth of permeable pavements for traffic areas. The Geoblock® Porous Pavement System offers support for all vehicular loadings and protects the grass from the damaging effects of traffic while allowing natural groundwater replenishment. Examples where ...

  • Product comparisons grasspave2 and gravelpave2 vs geoweb

    Presto Products manufactures “Geoblock” and “Geoweb” and have continuously tried to overturn projects specified with our Grasspave2 product since they became licensed to sell a geocell product developed by the US Army Corps of Engineers several years ago. Presto has done this because both of their “Geoblock” grass reinforcement paving products are more ...
