Although used in the Southeast since the 1980s, it is considered a new innovation in other parts of the nation.<\/p>\r <p class=\"wp-block-paragraph\">As is the case with products tried for the first time, there have been problems and job failures. Pervious concrete is very different than other types of concrete because of its mix design, placement procedures, and curing requirements, and slab replacements can result when best practices aren&#8217;t followed.<\/p>\r <p class=\"wp-block-paragraph\">In 2009 a residential street project in Shoreview, Minn. \u2014 a suburban area north of St. Paul \u2014 received national attention because it was the largest public street project in the country to use pervious concrete in lieu of storm sewers. The city installed about 1 mile of the porous pavement that will allow water to drain straight to the ground below and prevent runoff that can be damaging to waterways. There were no catch basins, pipes, or settling ponds. But this project also deserves a closer look because of the thoughtful and innovative forensic research conducted by the parties involved before the job even began.<\/p>\r <p class=\"wp-block-paragraph\">This is the second pervious concrete pervious project for Shoreview, the first being an alley installed in 2007. Tom Wesolowski, the city&#8217;s assistant engineer, says there were a few problems with the work, such as minor spalling and cracking, but it helped the city&#8217;s engineering staff to have realistic expectations.<\/p>\r <p class=\"wp-block-paragraph\">When it became clear the asphalt streets, lacking both curbs and storm sewers, in an older residential part of town needed replacing, the engineering department considered several options. The project area, adjacent to Lake Owasso, is considered an environmentally sensitive area. Options that would increase the level of contaminants and silt in the lake couldn&#8217;t be considered. The region&#8217;s sandy soil, which afforded good drainage, was ideal for pervious pavement and a factor that led to the city&#8217;s decision to specify pervious for the project.<\/p>\r <p class=\"wp-block-paragraph\">Although the pervious concrete option would be more expensive than options that included storm drainage, Wesolowski says the cost wasn&#8217;t considered significant when compared to the total value of the project.<\/p><p class=\"wp-block-paragraph\"><strong>BUILDING A SOLID SPECIFICATION<\/strong>\r <\/p>\r <p class=\"wp-block-paragraph\">Some pervious pavements fail as the result of insufficient subsoil drainage, especially in freeze\/thaw climates. Saturating pervious concrete must be avoided or frost-wedging can result, breaking the cement bonds holding the aggregate together.<\/p>\r <p class=\"wp-block-paragraph\">The Shoreview application required 1 to 3 feet of soil excavation, depending on land elevations. Parts of the project were sloped so low, areas would collect more water and needed deeper stone containments to prevent water from ponding in the pervious concrete.<\/p>\r <p class=\"wp-block-paragraph\">Wesolowski says the selection of aggregate in the subbase is important; it must be open graded and able to support the weight of ready-mix trucks without rutting during concrete placement. As a result, crushed angular 1\u00bd-inch top-sized rock was placed on top of soil-separation fabric.<\/p>\r <p class=\"wp-block-paragraph\">Recognizing the importance of good curing, the city also specified a seven-day wet-curing period using wet-curing blankets.<\/p>\r<\/li><\/ul><\/div> \r<p class=\"wp-block-paragraph\">\r \r<\/p>\r\r\r <strong>DESIGNING THE MIX<\/strong>\r <p class=\"wp-block-paragraph\">After gathering information about job failures from around the country, Kevin MacDonald, vice president of engineering services for Cemstone, a ready-mix producer in Medota Heights, Minn., designed the pervious concrete mix. By understanding the nature of pervious concrete job failures, he was able to avoid others&#8217; mistakes.<\/p>\r <p class=\"wp-block-paragraph\">Some failures were the direct result of poor curing, or no curing at all. \u201cCuring is important. You have to remember that the surface area of pervious is huge \u2014 everywhere inside the slab as well as on the top,\u201d MacDonald says. \u201cIn addition, cement paste layers are very thin so they are very susceptible to moisture loss.\u201d<\/p>\r <p class=\"wp-block-paragraph\">Pervious projects have failed because shale aggregates, present in the concrete, absorbed water and broke under freeze\/thaw conditions, even below the surface. Cement paste and sand in the fresh concrete of another project sank to the bottom of the placement and filled the void spaces. Other pervious slabs failed because mixes included a blend of coarse aggregate sizes, reducing void spacing.<\/p>\r <p class=\"wp-block-paragraph\">When MacDonald designed this project&#8217;s pervious mix, his priorities included: finding the right coarse aggregate, providing the correct amount of cementitious paste, and preventing the paste from moving after concrete placement. In terms of hardened characteristics, MacDonald says the internal void ratio should be in the 40% range and he considers flexural strength to be more important than compressive strength.

Technology to keep cement paste evenly dispersed is the next consideration. If it slumps down to the bottom of a placement, void spacing is diminished and the pavement is at risk.<\/p>\r <p class=\"wp-block-paragraph\">To achieve quality pervious concrete, point-to-point contact between aggregates is also important, which occurs with good compaction immediately following placement. This is probably achieved best with vibratory screeds or surface compaction provided with heavy weights. Void spaces are provided by the mix design so overcompaction isn&#8217;t a risk. \u201cYou can&#8217;t reduce void spaces beyond what large aggregate sizes permit,\u201d says MacDonald.<\/p>\r \r<p class=\"wp-block-paragraph\">\r \r<\/p>\r\r\r <strong>INNOVATING PRACTICES ON THE JOBSITE<\/strong>\r <p class=\"wp-block-paragraph\">Cliff Swenson, project manager and estimator for North Country Concrete, Ramsey, Minn., says his company has five years of pervious concrete installation experience. In terms of placement, they think problems mostly relate to how well the fresh concrete is compacted and how fast curing operations proceed. To address this, North Country Concrete purchased a ride-on roller screed that spanned the entire 21-foot-wide street, rolling on the curb and gutters that were constructed several days earlier. Two rollers guided the machine and screeded the concrete, while the third roller in the machine&#8217;s rear could be adjusted up or down to compact the concrete at \u00bd inch as the machine passed by \u2014 enough to provide the inter-aggregate connections needed.<\/p>\r <p class=\"wp-block-paragraph\">To solve the curing problem, North Country Concrete fabricated a moving platform with a water dip-tank to follow immediately behind the screed to perform the wet-curing operation. Workers pulled the curing membrane off a roll, passed it through the dip-tank full of water, and placed the wet material on the pavement. Swenson says when the curing membrane was removed, the pavement was still wet after seven days.<\/p>\r <p class=\"wp-block-paragraph\">Working with a 12-person crew, North Country placed as much as 200 cubic yards of concrete per day. Two ready-mix trucks arrived every 20 to 25 minutes, backing into position side by side to place concrete along the 22-foot width of the street. The material flowed down the shoots without assistance. Despite the additional admixtures and enhanced design, Swanson thinks the price of the concrete was in line with other pervious mixes North Country has worked with in the past.<\/p>\r <p class=\"wp-block-paragraph\">It&#8217;s a little unusual for all parties in a contract to adopt a leading-edge philosophy and work together to solve problems. The City of Shoreview had realistic expectations for the project but also wanted a state-of-the-art result. This was ensured by involving all of the players in early problem-solving discussions.<\/p>\r <p class=\"wp-block-paragraph\">City engineers also recognized that the pavement would only be as good as its maintenance system so they periodically employ a truck-mounted vacuum to remove debris and dirt from the pores of the concrete throughout the nonwinter season. During the winter months, the city avoids using sand or salts to remove snow and ice as much as possible.<\/p>\r <p class=\"wp-block-paragraph\">Every good project studies the outcomes, so the city is monitoring the water in Lake Owasso and the wells in the area. At some locations, they can tell how much water is residing in the open-graded stone layer below the pavement. Due to unusual weather conditions this past winter, a layer of snow and ice residing on the surface of the pavement made any damage unclear. But during spring, project participants walked the street to determine how it survived its first winter.<\/p>\r <p class=\"wp-block-paragraph\">\u201cThe concrete held up well,\u201d says Wesolowski. \u201cThere were a few isolated areas where spalling of the first layer of rock occurred, but that accounted for only approximately 2% of the total surface area.\u201d The affected areas are mainly located on curves where the city was forced to place salt due to freezing rain and extremely cold temperatures in December.<\/p>\r <p class=\"wp-block-paragraph\">\u201cWe are speculating that the salt combined with the turning movements on the curves caused the spalling.\u201d<\/p>\r <p class=\"wp-block-paragraph\">As anticipated by the engineering department, the improved technology provided better pavement compared to the first pervious project a couple of years ago. According to Wesolowski, the pavement in the alley has many more pores at the surface and looks more like the typical pictures you see of pervious concrete. But the combination of the mix design and tri-wheel roller on the street project produced a much tighter surface.<\/p>\r <p class=\"wp-block-paragraph\">\u201cIt looks like it is almost too tight for water to flow through it,\u201d he says. \u201cAlso, if you look at a cross-section of the concrete you can see that the top 1 to 2 inches is more tightly compacted than the lower portion, which is directly related to the pressure the roller paver placed on the surface of the concrete. That should make the surface more durable.\u201d<\/p>\r <p class=\"wp-block-paragraph\">Shoreview will evaluate this project for the next few years to ensure it meets performance expectations.<\/p>\r
