If the liquid anti -strip agent has been modified then a <br />new sample shall be submitted to the Department and tested per 916-5.1. <br />916 -5.3 Mix Design Verification: Inclusion of a liquid anti -strip agent on the QPL <br />j does not guarantee that the anti -strip will be approved for use in an asphalt mixture. <br />Specifications may require subsequent moisture susceptibility testing per FM 1 -T 283 for <br />the particular mix design. Results from this testing may indicate the need for a larger <br />dosage rate of anti -strip agent (up to 0.75% maximum) or a different anti -strip agent to <br />meet the specification requirements. <br />923 WATER FOR CONCRETE - CHEMICAL REQUIREMENTS. <br />(REV 4- 25 -05) (FA 6- 30 -05) (1 -06) <br />ARTICLE 923 -3 (Page 803) is deleted and the following substituted: <br />923 -3 Chemical Requirements. <br />923 -3.1 Testing: All chemical analysis or test shall be performed in accordance with <br />AASHTO T 26 or Standard Methods for the Examination of Water and Wastewater. <br />923 -3.2 Reclaimed Water: Water from mixer washout and recycled wash water <br />shall be tested and approved before use and shall not exceed the following allowable <br />limits: <br />Chemical Test <br />Maximum ( %) <br />Equivalent Alkalis as (Na20 + 0.658 K20) <br />0.06 <br />Total Solids <br />5.00 <br />Total Chlorides as Sodium Chloride <br />0.05 <br />Sulfate as SO, <br />10.30 <br />923 -3.3 All Other Sources: Water from all sources, other than public health <br />approved sources, shall be tested and approved before use and shall not exceed the <br />following allowable limits: <br />Chemical Test <br />Maximum (%) <br />Acidity or alkalinity calculated in terms of <br />calcium carbonate <br />0.05 <br />Total organic solids <br />0.05 <br />Total inorganic solids <br />0.08 <br />Total chlorides as sodium chloride <br />0.05 <br />N <br />u. <br />1 <br />r: r •s,, <br />`V� 4 <br />IMarch 2007 01000 -174 03- 4122.D <br />
