We can send our team of experts out to test your property for materials we need. %PDF-1.6 % (Provides improved Product Quality, Consistency, Predictability, and Acceptance). If the pavement structure cross sections show aggregate base to be placed on soil, verify the design Rvalue by testing the basement material at the grading plane to verify the planned aggregate base thickness shown in the pavement structure. The subgrade tolerances can be found in the specification for the subgrade material. (Refer to Section 3-609A, Operating Range and Contract Compliance, of this manual.) hbbd``b` $? When measuring for compliance, spot-check the staked locations and areas between stations where stakes are set. Uh oh, there was an error sending your message. Intermittent sampling and testing of aggregate base materials. Observe the compacting operation to ensure that the material forms a uniformly firm, stable base. Include in the project records an explanation of why you reduced R-value testing. Ensure that the geosynthetic materials are not damaged during placement, spreading, and compaction of the aggregate base. %%EOF 1" minus Reclaimed / Unclassified Gravel (when available), Asphalt Millings, screened to 1" and less (When Available), KD Recycling, Inc. provides a wide range of aggregates. Observe the spreading and compacting operation to ensure that it conforms to the layer thickness requirements of the specifications. If a test result fails to meet the requirement for contract compliance, you may test additional previously taken samples to determine the quantity of material represented by the failing test result. ]?qqxtFJ;@\F"l?~y12\GvP*Ts5Kc&m^VY@{. Water will percolate through a trench filled with aggregate more quickly than it will through the surrounding soil, thus enabling an area to be drained of surface water, useful in wet or marshy areas, or to provide a solid base in driveways, which have a tendency to be too soft for vehicle transit. Aggregates are used in construction and landscaping to provide drainage, fill voids, protect pipes, and to provide hard surfaces. Ensure the contractor is actively performing quality control on aggregate base materials throughout production operations by reviewing copies of quality control records, including quality control test results. Note in the daily report any inspections performed on items that are not otherwise part of a permanent record. )FP#$&;*+/Iu[iU6m|h :@]qP )Co;YCs@&&Ydplo0IUd= ~h+.tT#bq(UW^m|B"1e[iJGOL.

For instance, you do not need to note any compaction tests taken, because these are recorded elsewhere. Aggregate base is designated as Class 2 or Class 3. 53089 0 obj <>stream Aggregates generally are not affected by the weather as much as soils, particularly clay soils. The smart choice for playgroundsimproves safety, drainage and overall sanitation. Make quantity calculations as early in the project as possible. Normally you would verify this through observation, but if problems persist, support your observations with a sieve analysis. Intermittent inspection of placement, spreading, and compaction operations. Determine the extent of this measurement based on factors such as the nature of material, the efficiency of the contractors operation, and the accuracy of the grading operation (as indicated during the early stages of checking). uyy i(Q0Q6]XXBXIc[%h6g.%yffzf~)D jyPDV#EH?Gv`aj\|6'BV06:p/sS4~ %D~0 ->U Stability: Resist deformation when under load (after proper placement and compaction). Durability: Resist degradation due to use (after proper placement and compaction). If aggregate base will be paid for by volume, calculate the volume based on the dimensions shown on the plans. Where geosynthetic materials are shown, ensure materials are properly placed, including overlapping requirements and securely holding materials in place during aggregate base placement. If so, Gowan Construction would like to hear from you. Determine whether the contractor has complied with all requirements related to the use of local materials. Aggregate Baserock is a dense graded blend of coarse and fine aggregate which when properly placed and compacted provide a stable and durable base allowing further construction.Aggregate Baserock Should Demonstrate: ADVANTAGES OF USING BASEROCK FROM WILSON QUARRY (AROMAS). 53063 0 obj <> endobj endstream endobj startxref Time and frequency of submitting test results.

Action and suspension limits, and details of corrective action to be taken if any process is outside of those limits. Building a shed or summerhouse in your yard? Before placement begins, review the contract plans and specifications to determine the aggregate base requirements. Ensure that the aggregate base is spread on the subgrade without significant segregation. 763.441.1100 This section provides guidelines for inspecting aggregate bases for work specified under Section 26, Aggregate Bases, of the Standard Specifications. If payment is by weight, measure waste and deduct those quantities. Note that it is prudent to take frequent samples, especially with borderline test results, but test only at the frequency shown in the table in Section 6-1 of this manual. Specifications provide limits on the contractors equipment and operations. Measure the subgrade grading plane for compliance with elevation tolerance requirements for the material involved. If mutually agreed with the contractor, hold a preconstruction meeting with the contractor and the district Materials Unit prior to construction to discuss the quality control plan and contractors method for performing each element of work affecting material quality, including acceptance testing priorities, shipping of samples, lines of communication for test results, timeframes for reporting quality control and acceptance test results, and any contractual testing dispute resolution processes. endstream endobj 53064 0 obj <> endobj 53065 0 obj <>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/StructParents 38/Type/Page>> endobj 53066 0 obj <>stream You also need to note that construction is being performed according to specified layer thicknesses, because this information is not recorded elsewhere. (Refer to Topic 614, Soil Characteristics, in the, Test potential sources of aggregate base when the contractor requests such testing in writing. Consider reducing frequency when the initial test results show R-values significantly exceeding the specified R-value and ongoing gradation and sand equivalent test results indicate acceptable and consistent material quality.

If aggregate base will be paid for by weight, obtain the optimum moisture content from the aggregate base moisture-density compaction curve and sufficient moisture samples to determine pay quantity adjustments. Deduct applicable Caltrans costs for sampling and testing from contract payments as required under Section 6-1.03. Review compaction tests of the subgrade that is to receive aggregate base. @YHpULYL?HP$M` When preparing the foundations, gaps and trenches may be filled with aggregate, because it is easier to compact than the original soil that was removed, resulting in a more solid finish that will support the structure. }#mkK/_vNV/*B41C~~q
