ACI 522.1M-20 Specifcation for Construction of Pervious Concrete Pavement.
3.8—Final surface texture 3.8.1 Final surface texture shall match that of appearance of test panel. 3.9—Jointing 3.9.1 Construct joints at locations, depths, and with toler- ances given in horizontal dimensions indicated in Contract Documents. 3.9.2 Create contraction joints by one of the methods listed in 3.9.2.1 or 3.9.2.2. 3.9.2.1 Sawcut concrete after concrete has hardened sufciently to prevent aggregate from being dislodged and before pavement cracks. Immediately fush or vacuum the area adjacent to the joint to remove the dust or slurry created by sawing. If plastic sheeting is removed to sawcut joints, minimize loss of moisture by removing only the area being sawcut, then moisten the uncovered area and replace plastic sheeting. 3.9.2.2 Tool contraction joints to specifed depth and width in fresh concrete immediately after striking of. 3.10—Curing 3.10.1 Unless otherwise specifed, begin curing within 10 minutes of concrete discharge, unless other accepted steps are taken to extend placement and fnishing time. 3.10.2 Clearly identify new concrete and protect using warning tape or other barricades to clearly identify and prevent damage during curing period and cure concrete in accordance with 3.10.2.1. 3.10.2.1 Cover the pavement surface and all exposed edges with polyethylene sheeting. Thoroughly secure polyethylene sheet at all exterior edges and interior laps without using soil. The method of securing cover material shall prevent wind from removing the sheet and from blowing under the sheet across surface of the concrete. 3.10.3 Unless otherwise specifed, cure pavement for at least 7 days.
General notes G1. ACI Specifcation 522.1 is to be used by reference in the Project Specifcation. Do not copy individual sections, parts, articles, or paragraphs into the Project Specifcation because taking them out of context may change their meaning. G2. If sections or parts of ACI Specifcation 522.1 are copied into the Project Specifcation or any other document, do not refer to them as an ACI specifcation. G3. A statement such as the following shall serve to make ACI Specifcation 522.1 a part of the Project Specifcation: “Work on (Project Title) shall conform to all require- ments of ACI 522.1 “Specifcation for Pervious Concrete,” published by the American Concrete Institute, Farmington Hills, Michigan, except as modifed by these Contract Documents.” G4. ACI Specifcation 522.1 is written in the three-part section format of the Construction Specifcations Institute, as adapted for ACI requirements. G5. If ACI Specifcation 522.1 is referenced in Contract Documents along with another ACI specifcation that contains overlapping provisions, identify which require- ments are in confict and state in Contract Documents which requirements govern. FOREWORD TO CHECKLISTS F1. This foreword is included for explanatory purposes only; it is not a part of ACI Specifcation 522.1. F2. ACI Specifcation 522.1 may be referenced by the specifer in the Project Specifcation for any building project, together with supplementary requirements for the specifc project. Responsibilities for project participants must be defned in the Project Specifcation. ACI Specifcation 522.1 cannot and does not address responsibilities for any project participant other than Contractor. F3. Checklists do not form a part of ACI Specifcation 522.1. Checklists assist the specifer in selecting and speci- fying project requirements in the Project Specifcation.ACI 522.1M pdf download.
