Asphalt Inspection San Diego

What it is: Asphalt is a heated mixture of rock / sand (aggregate), and crude oils primarily used in road construction.

What it does: Steel drum rolled asphalt concrete once compacted over a firm base material provides flexible pavement to support traffic loads. In addition, asphalt is placed at a specified percent fall to divert water from the driving surface.

What we do: During the process of construction we check the subgrade soils and base material for relative compaction as required in the plans and engineered soils report. Also, check for soft and yielding subgrade areas which need to be reworked to a firm and unyielding condition. Once the subgrade and base material is in place and compacted the paver crew begin laying asphalt while an asphalt sample is obtained for unit weight and oil content in the lab. During placement and compaction of the asphalt pavement we consistently check temperature and relative compaction while updating the contractor on results during placement. Once, lab results are obtained we then submit reports to the owner and design engineer.

Aggregate Testing: Metzger Testing & Inspection obtains samples of aggregate materials for lab testing and sieve analysis.

Asphalt Field Services: We provide personnel and equipment to test the base material compaction followed by the compaction of asphalt paving. This may include a mobile laboratory, or we may simply provide personnel to inspect and assist with placement activities. This service fulfills a valuable role in the third-party quality assurance process.

Reinforcing Steel Inspection

Re-bar are steel bars of various diameters and lengths which have steel ribs that add to the bonding value of concrete for adhesion and additional strength. Reinforcing steel and concrete are bonded together by a mechanical connection.This provides the tensile properties which adds another element of strength to the concrete.

Field Concrete Testing

The testing of concrete at the construction site is to sample the freshly mixed concrete, check for slump, temperature and cast a set of cylinders for compressive strength verification. Slump is a field test to measure water quantity mixed within the concrete. This is mainly for field-use measurement as a guide for the work-ability of concrete.

Post-Tension Concrete

Post-tension concrete cables are long steel cable ropes, usually 1/2″ in diameter within a plastic protective grease coated sheathing. Post-tension concrete cables are a group of cable tendons placed within the concrete providing compression strength laterally. Post-tension concrete cables which are placed within the concrete allows the concrete to be elevated as it has compressive lateral strength.

Welding Inspection

Steel is the structural soundness and integrity of the building. If welding is not done by code or procedure it could result in defective work which would lead to the removal of weld areas by grinding and re-welding. As Certified Welding Inspectors Metzger Testing & Inspection can provide guidance to the contractor in producing a welding procedure specification…
