Limits of Construction: The Contractor shall construct the base to the full width shown on the Drawings. 3.2 PERFORMANCE A. Excavation: The .area in which the widening is to take place and the limerock base is to be placed shall be excavated to the depth and dimensions shown in the Drawings. The underlying subgrade shall be compacted sufficiently to assure that no distortion will occur with the placement of the limerock base. B. Transporting Limerock: The limerock shall be transported to the point where it is to be used, over rock previously placed if practicable, and dumped on the end of the preceding spread. No hauling over the subgrade or dumping on the subgrade shall be done. C. Spreading Limerock: 1 . The limerock shall be spread uniformly, and all segregated areas of fine or coarse rock shall be removed and replaced with well-graded rock. 2. When the specified compacted thickness of the base is greater than 8-inches, the base shall be constructed in two courses. The 4/9/99 LIMEROCK BASE 02232-2 thickness of the first course shall be approximately one-half the total thickness of the finished base, or enough additional to bear the weight of the construction equipment without disturbing the subgrade. D. Compacting and Finishing Base: 1 . General: a. For single course base, prior to spreading, the specific section requiring base shall be scarified and then shaped so as to produce the required grade and cross section after compaction. b. For double course base, the first course shall be cleaned of foreign material, bladed & brought to a surface cross section approximately parallel to that of the finished base. Prior to the spreading of material for the upper course, the density tests for the lower course shall be made and the County Engineer shall have determined that the required compaction has been obtained. After the spreading of material for the second course is completed, its surface shall be finished & shaped so as to produce the required grade & cross section after compaction and free of scabs & laminations. 2. Moisture Content: When the material does not have the proper moisture content to insure the required density, wetting or drying will be required. If the material is deficient in moisture, water shall be added and uniformly mixed in by discing the base course to its full depth. If the material contains an excess of moisture, such excess shall be reduced or removed until the required moisture is attained before being compacted. Wetting or drying operations shall involve manipulation of the entire width and depth of the i base as a unit. 3. Density Requirements: As soon as proper conditions of moisture are attained, the material shall be compacted to a density of not less than that currently existing on the compacted surface. 4. Density Tests: a. During final compacting operations, if blading of any areas is necessary to obtain the true grade and cross section, the compacting operations for such areas shall be completed 4/9/99 LIMEROCK BASE 02232-3 prior to making the density determinations on the finished base. b. At least one density determination shall be made at each - location where limerock is placed on each day's final operations on each course, & the density determinations shall be made at more frequent intervals if deemed necessary by the Engineer. 5. Correction of Defects: a.. If at any time the unsuitable material should become mixed with the base course material, the Contractor shall dig out and remove the mixture, reshape and compact the subgrade and replace the materials removed with clean base material, which shall be shaped and compacted as specified above. b. If cracks or checks appear in the base, either before or after priming, which in the opinion of the Engineer would impair the structural efficiency of the base course, the Contractor shall remove such cracks or checks by rescarifying, reshaping, adding base material where necessary and recompacting. E. Testing Surface: The finished surface of the base course shall be sufficient so that when the asphalt surface course is applied, no irregularities exist or appear after traffic is placed on the final surface. All irregularities shall be corrected by scarifying & removing or adding limerock as may be required, after which the entire area shall be recompacted as specified herein before. F. Thickness Determinations: The thickness of the compacted limerock base shall vary to achieve the final elevations as shown on the plans. G. Priming and Maintaining: 1 . The prime coat shall be applied only when the base meets the specified density requirements and the moisture content in the top half of the base does not exceed 90 percent of the optimum Li moisture content of the base material. At the time of priming, the base shall be firm and unyielding. 2. The Contractor will be responsible for assuring that the true crown and grade are maintained with no rutting or other distortion and 4/9/99 LIMEROCK BASE 02232-4 that the base meets all the requirements at the time the surface course is applied.
