Vocabulary practice flashcards covering road design, traffic metrics, coastal structures, materials testing, geotechnical terms, and construction safety from CECC481.

Density (Traffic)

The number of vehicles per unit distance occupying a section of roadway at a given instant in time, usually measured in vehicles per mile or vehicles per kilometer.

Wharf

A continuous structure built parallel to along the margin of the sea or alongside riverbank, canals, or waterways where vessels may lie alongside to receive or discharge cargo, embark, or disembark passengers or lie at rest.

Deep Water Wave

A wave at a point where the water depth is equal to one-half of the wavelength or greater to be expressed in terms of the parameters of significant wave.

Construction Safety and Health Program

Detailed rules to cover the processes and practices that shall be utilized in a specific project site in conformity with the OSHS including the personnel responsible and the penalties for violation thereof.

Concrete

Any material consisting of mixture of aggregates, such as sand, gravel, or crushed stone, fastened together by cement.

Hardness

A measure of materials ability to resist indentation or penetration.

Consolidation

An increase in soil density of a cohesive soil resulting from the expulsion of water from the soil void spaces.

Standard Weight Concrete Slab Finishing Order

Bleeding-Screeding-Leveling-Edging-Jointing-Floating-Troweling-Broom Finishing.

Health and Safety Committee

The body given the authority to review reports of inspection, accident, investigations, and implementation of the program.

Grouting

The process of injecting any agent into soil or rock to increase its strength or stability, protect foundations or reduce ground water.

Design Reaction Time

A value of $2.5\,\text{sec}$ used for road safety design, applied to the whole range of design speeds.

Types of Pavement and Curb Markings

Longitudinal lines, transverse lines, other lines, and other markings.

No Loading/Unloading Zone Markings

Pavement markings indicated by the color red.

Chevron Signs

Signs used to guide drivers through a change in horizontal alignment of the road.

Skidding

The motion resulting when a path travelled along the road surface is more than the circumferential movement of the tires due to rotation.

Sag Curve

A vertical curve that occurs when a negative gradient is followed by a positive gradient.

Elimination (Hazard Control)

A type of hazard control considered to be the most effective, which involves physically removing the hazards.

Essential Elements of Fire

Fuel, Heat, Oxidizing-agent, and an uninhibited chemical chain reaction.

Lean Over Collapse

A collapse limited to wood frame structures characterized by a wooden building that shifts at the upper levels, leaning into adjacent buildings or totally collapsing sideways in the absence of adjacent buildings.

Falls (Construction)

The type of accident responsible for approximately $50\%$ of construction-related fatalities.

Personal Protective Equipment (PPE)

Equipment worn by construction workers to minimize the risk of injury from workplace hazards such as falling objects, sharp materials, chemical splashes, excessive noise, and adverse weather conditions.
