MSTE

• Alligator cracking is a series of interconnected or interfaced cracks caused by fatigue failure of the asphalt concrete surface under repeated traffic loading.
• Amplitude is the height between the trough and the crest of a wave.
• Asphatic Concrete is a layer consisting of properly designed mix of coarse aggregate, fine aggregate, a filler and a bituminous binder.
• Average speed is the average of the spot speeds of all vehicles passing a given point in the highway.
• Barriers are highway appurtenances designed to prevent vehicular penetration from the travel way to minimize damage to impacting vehicles and their occupants and to reduce the risk of injuries to pedestrians and workers.
• Base is the component of the road structure which receives the traffic load and transfers it to the subgrade.
• Base courses normally consist of aggregates such as gravel and crushed rock.
• Basic capacity is the maximum number of passenger cars that can pass a given point on a lane or roadway during one hour under the most nearly ideal roadway and traffic conditions which can possibly be attained.
• Batching is the process of proportioning cement, water, aggregates and additives prior to mixing concrete. Most important process.
• Bathymetry is the physical configuration of the seabed, the measurements of depths of water in the ocean, etc.
• Beuforts Scale is an instrument used to measure intensity of wind.
• Bitt is the mooring fitting for mooring ships during a storm installed close to the water line of the berth.
• Bitumen carpet is a 20 mm thick premix bitumen layer over which is laid a seal coat.
• Bleeding or flushing is the exuding of bitumen onto the pavement surface causing a reduction in skid resistance. After placement, they have the tendency to settle to the bottom and displace the mixing water to the surface.
• Block cracking is a type of cracking that forms large interconnected polygons, usually with sharp corners or angles, and is generally caused by hardening and shrinkage of the asphalt and/or reflection cracking from underlying layers such as cement treated base.
• Distance gaps are defined as the fraction of time that vehicles are present at a point in space.
• Diverging is the process by which a vehicle in a traffic stream leaves that traffic stream, such as a vehicle leaving the outside lane if an expressway.
• Duration is the time that a wind blows across the water.
• Distance separation is the reciprocal of density which is usually measured in vehicles per mile or per kilometer.
• Estimates include cost estimates for various parts of the project and are used to evaluate the acceptability of bids and financial feasibility of the project.
• Diverging conflicts are traffic conflicts that occur when vehicles leave the traffic stream.
• Dry dock is an artificial basin for vessels when the basin is pumped out.
• Expressway is a divided arterial highway for through traffic with full or partial control of access and generally with grade separations at major intersection.
• Facility oriented organization is primarily involved in planning, designing, constructing, maintaining, and operating fixed facilities.
• Fairway is an open water with navigable depth.
• Faulting is the elevation difference between adjacent slabs at traverse joints.
• Engineering quantities are normally expressed as volumes, in metric units, they are given in cubic meters.
• Drainage is the primary consideration in the design of geometric cross sections for highways, runaways, and taxiways.
• Elevation is measured in meters above some datum; usually this datum is mean sea level, but it may be any arbitrary scale.
• Emotion is the time linked with the two stages perception and intellection based on a particular traffic situation like fear or anger which has a vital influence on the final message or decision sent by the brain to the muscle.
• Drip track raveling is the progressive disintegration of the surface between the heel paths caused by dripping of a gasoline or oil from vehicles.
• Diurnal tides are tides which occur only one high tide a day.
• Diffraction refers to the spread of energy along a wave crest.
• Blowups are localized upward buckling and shattering of the slabs at traverse joins or cracks.
• Breakwater is the structure that protects harbor from stormy waves and permits calm in the harbor.
• Braking distance is the distance traveled by the vehicle after the application of the brakes until it will stop.
• Breaking waves are waves which fall forward since the forward velocity of the crest particles exceeds the velocity of propagation of the wave itself.
• Wave height is the elevation of the crest above the through of the wave.
• Wind is the circulation of masses of air more or less parallel to the earth’s surface.
• Vertical curve are normally parabolas centered about the point of intersection of the vertical tangents they join.
