Our certified technicians will sample soil and aggregate <br />using ASTM Standard Practice D75 for the appropriate laboratory testing, which may include sieve <br />analysis, sand equivalent, cleanness value, R-value, maximum density, specific gravity, durability, <br />soundness, and expansion potential. <br />Bituminous Mixture Sampling and Testing. Our certified technicians will sample asphalt concrete <br />mixtures in the field or at the batch plant using ASTM D979 for laboratory testing which may include <br />maximum theoretical unit weight, asphalt extraction, stability, moisture and rutting susceptibility, and <br />gradation analysis. <br />Soil and Base Compaction Testing. Our certified technicians observe placement of soils and <br />aggregate base material and conduct field testing using a nuclear gauge device or sand cone to <br />evaluate the in -place density and moisture of the material and to calculate relative compaction. <br />Results of soil and aggregate base compaction and density testing taken at the job site will be <br />submitted to the City's designated representatives within 24 hours. <br />Micro -surfacing and Slurry Seal. Our certified technicians observe the placement of slurry seal, <br />scrub seal and micro -surfacing materials for resurfacing of the existing roadways. They check for <br />oversize material, monitor mix temperature, proper mixing, and blending of the mix. Our inspectors <br />can also collect samples of slurry seal for wet -track abrasion testing. <br />Asphalt Compaction Testing. Our certified technicians observe placement and compaction of HMA <br />material using nuclear density gauges in accordance with California Test Method 375. Results of <br />asphalt compaction and density testing taken at the job site will be submitted to the City's <br />designated representatives within 24 hours. <br />Asphalt Batch Plant Inspection. Our certified technicians routinely provide batch plant inspection <br />during paving operations to observe and document material quantities, mixing temperatures, binder <br />type and temperatures. They collect samples of asphalt and aggregates and conduct moisture tests <br />and grain size analysis. They also ticket the load for identification by the field inspector. <br />Concrete Batch Plant Inspection. Our certified technicians perform observation and documentation <br />of procedures used in concrete batching. At the batch plant, the inspector monitors and records <br />weights of ingredients for concrete, including admixtures. They also monitor mixing of concrete, <br />slump, addition of water, and adherence to the approved mix design. They will ticket the load for <br />identification by the field inspector. <br />Inspection of Reinforcing Steel at the Fabrication Plant. Our deputy inspectors identify and <br />sample reinforcing steel at the fabrication plant and tag the steel for recognition upon arrival at the <br />project site. We also collect samples of reinforcing steel which are transported to our facility for <br />laboratory testing (bend and tensile) as required by the project plans and specifications. <br />'KLEINFELOER <br />M IPM2u):nP Kleinfelder 1 16 `--- <br />
