Unit Weight

The weight of concrete per volume used to assess material density.

Flexural Strength

The ability to resist deformation under load, often measured in psi.

Air Content

The amount of entrained air in concrete which affects durability.

Water/Cementitious Ratio

The ratio of the mass of water to the mass of cement in a concrete mix, critical for workability and strength.

Paving Equipment

Includes machines like finishing machines, spreaders, and slip-form pavers used in concrete pavement construction.

Quality Control Plan (QCP)

A document outlining how concrete production, handling, and testing will be managed to meet quality standards.

Dowel Bars

Steel bars used to allow for thermal movement at pavement joints.

Transverse Joints

Joints that are installed across the pavement to control cracking.

Longitudinal Joints

Joints installed along the direction of traffic to reduce stresses due to thermal expansion.

Curing

The process of maintaining adequate moisture, temperature, and time to allow the concrete to achieve its desired strength.

Quality Assurance (QA)

INDOT's responsibility to assess whether concrete meets contract requirements.

Unit Weight Testing

A method to determine the density of the concrete mix, significant for quality control.

Smoothness Tolerance

Limits on the variations in surface flatness of the concrete pavement.

Trial Batch Demonstration

A test run to verify concrete mixes and ensure all equipment is calibrated before actual production begins.

Failed Materials Process

A review procedure for materials that don’t meet specifications to determine necessary actions.

Sampling Procedures

Processes used to collect concrete samples for testing to ensure compliance with standards.

Construction Specifications

Detailed descriptions of the standards and requirements for construction work, such as materials and methods.

Payment Factors

Adjustments made to payments based on the quality of concrete as determined by testing.

Coring

The process of drilling out a sample from newly constructed pavement to assess thickness and quality.
