5-06.3(6)A Infiltration Rate of the Placed Pavement <br /> The infiltration rate of the pervious concrete shall be determined at four(4) random locations <br /> within each lot. The locations for conducting infiltration tests will be determined by the Engineer. <br /> The Contractor shall coordinate and schedule testing with the Engineer a minimum of five (5) <br /> Working Days in advance. The infiltration rate on the finished surface will be determined in <br /> accordance with ASTM C1701, except the infiltration ring diameter may be 12-inches to 24- <br /> inches in diameter. The infiltration test will be conducted after a minimum of seven (7) calendar <br /> days of curing has occurred. <br /> If the measured infiltration rate is less than 100 inches/hour at any test location, the Contractor <br /> may request in writing that the Engineer perform additional infiltration tests for the purpose of <br /> assessing overall infiltration performance and/or determining a defective lot in accordance with <br /> Section 5-06.3(6). The determination of a defective lot, or lots, and the extent(s), will be by the <br /> Engineer. The cost of additional testing shall borne by the Contractor. <br /> 5-06.3(7) Rejection <br /> Pervious concrete may be rejected by the Contractor for any reason. <br /> A truckload of pervious concrete will be rejected if the Certificate of Compliance is not provided <br /> at the time of delivery of the material to the site. See Section 5-06.3(4)B. <br /> Pervious concrete that is improperly cured or is allowed to freeze during the initial seven (7) day <br /> curing period will be rejected. <br /> Pervious concrete pavement that does not meet the acceptance criteria put forth in Section 5- <br /> 06.3(6) will be rejected by the Engineer on a lot by lot basis. <br /> During the removal process of the rejected pavement, The Contractor shall implement <br /> measures to protect the adjacent pervious concrete pavement to remain. If pervious concrete <br /> pavement becomes damaged by the Contractor during removal of the rejected pavement then <br /> additional pavement areas may be rejected by the Engineer to the next planned joint. <br /> Fresh pervious concrete that has been rejected by the Engineer, or the Contractor, shall not be <br /> placed, or shall be removed and replaced, at no additional cost. <br /> 5-06.3(8) Mixing Pervious Concrete <br /> Batch, mix and deliver pervious concrete in compliance with ASTM C94/C94M except that <br /> pervious concrete shall not be transit mixed or shrink mixed. If water is added to the mix after it <br /> is delivered on site, the fresh density for the pervious concrete shall meet the requirements of <br /> the approved JMF referenced in this section. <br /> 5-06.3(8)A Limitations of Mixing Pervious Concrete <br /> Mixing and placing concrete shall be discontinued when a descending air temperature in the <br /> shade away from artificial heat reaches 40° F and shall not be resumed until an ascending air <br /> temperature in the shade and away from artificial heat reaches 40° F. <br /> The temperature of fresh pervious concrete shall not be less than 55° F, nor more than 90° F <br /> when placed. <br /> Pervious concrete shall not be mixed with aggregates at less than 32° F. <br /> Swift Green Line—Corridor Stations Special Provisions SP83 <br /> May 2017 <br />
