<br />Listed below are the standard materials testing and inspection services which we expect to perform
<br />on this contract and have provided for similar on -call contracts -
<br />Soil and Aggregate Sampling and Testing. 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, K-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 />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. al.,n,. is : f

<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 sire 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.
