Bridge & Roof Co QA QC Supervisor Interview Questions and Answers

There are several types of steel tests including tensile test, hardness test, impact test, and bend test.

• Tensile test measures the strength of steel by pulling it until it breaks.

• Hardness test determines the resistance of steel to indentation or scratching.

• Impact test evaluates the toughness of steel by subjecting it to sudden loading.

• Bend test assesses the ductility of steel by bending it to a specific angle without f

DLC (Dry Lean Concrete) and PQC (Pavement Quality Concrete) mix designs are crucial for ensuring durability and strength of roads.

• DLC mix design typically includes a low water-cement ratio to achieve high strength and durability.

• PQC mix design focuses on achieving a smooth surface finish and good skid resistance.

• Proper selection of aggregates, cement, and admixtures is essential for both DLC and PQC mix designs.

The rate of loading for flexural testing machine for PQC beam should be as per relevant standards and specifications.

• Rate of loading should be as per relevant standards such as ASTM C78/C78M for flexural testing of concrete beams

• Typically, the rate of loading is around 0.05 to 0.1 MPa per second for PQC beams

• The rate of loading should be uniform and controlled throughout the test to ensure accurate results

The Loto system stands for Lockout/Tagout, a safety procedure used to ensure that dangerous machines are properly shut off and not started up again during maintenance or servicing.

• Loto system involves locking the energy-isolating devices with individual lockout devices to prevent the machine from being turned on

• Tagout involves placing a tag on the locked device to indicate that it should not be operated
