The Engineer may vary the <br /> application rate of stabilizing agents as dictated by changes in the existing pavement conditions. <br /> The Contractor shall determine the amount of additional water needed to facilitate uniform <br /> mixing with the stabilizing agents and achieve a stable reclaimed layer at or above the minimum <br /> specified density. The water maybe added prior to or concurrently with the stabilizing agents. <br /> Adding water to facilitate uniform mixing shall not adversely affect the stabilizing agents. <br /> a) Portland Cement Stabilizing Agent -The Portland Cement stabilizing agent shall be <br /> controlled within ± 0.50% of the target established by the mix design. The specified <br /> quantity of stabilizing agent shall. be applied uniformly in a slurry and in a manner that <br /> minimizes dust and is satisfactory to the engineer. If multiple passes of the equipment <br /> are required to reclaim the pavement material to the desired width, a minimum 6 inch <br /> overlap shall be used. The application system shall be capable of adjusting for the width <br /> of recycling reclaiming such that overlapped mixture maintains•the designed Portland <br /> cement agent residual content. <br /> 1) Cement Stabilizing Agent, Placement: <br /> a. The time from cement placement on the pulverized material to start of mixing <br /> shall not exceed 30 minutes. <br /> b. The time from first contact of cement with water to application on the pulverized <br /> material shall not exceed 30 minutes. <br /> c. The operation of cement application, mixing, spreading, compacting, and <br /> <br /> . finishing shall be continuous and completed within 3 hours from the start of <br /> mixing. <br /> Special Provisions -Job #4624 Page 8 of 15 <br /> <br />
