	Pavement (roads) - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-07)
		Most asphalt pavements are built on an imported gravel base which is generally at least as thick as the asphalt layer, although some 'full depth' pavements are built directly on the native subgrade.
		Brick, cobblestone and wood plank pavements were once common in urban areas throughout the world, but due to their high manual labor requirements they are typically only maintained for historical reasons.
		As pavements primarily fail due to fatigue (in a manner similar to metals), the damage done to a pavement increases exponentially with the axle load of the vehicles traveling on it.

	Pavement (from roads and highways) -- Encyclopædia Britannica
		Road traffic is carried by the pavement, which in engineering terms is a horizontal structure supported by in situ natural material.
		The primary function of a pavement is to transmit loads to the sub-base and underlying soil.
		Modern flexible pavements contain sand and gravel or crushed stone compacted with a binder of bituminous material, such as asphalt, tar, or asphaltic oil.

	Graniterock: Technical Note - Paving The Way For Smoother Roads
		Although there are differences between the two types of pavement, some basic guidelines that apply to both are mix consistency (slump and gradation for concrete; gradation, temperature and binder content for asphalt), a continuous paving process, well planned and well executed rolling patterns, and the use of profilographs and profilometers for measuring results.
		Pavement smoothness is a tangible, measurable thing that contractors can be innovative in their ideas and equipment used to achieve desired results.
		Grinding the existing road surface and then paving is considered two opportunities for improvement, since the road can be made smoother by profile grinding and then again during the addition of the new pavement.

	Gravel Roads Better Than Pavement on Permafrost, Alaska Science Forum (Site not responding. Last check: 2007-10-07)
		The primary benefit to gravel roads is that they are relatively immune from frost heaving and have less of a tendency to thaw underlying permafrost.
		This is not to say, however, that all gravel roads are inexpensive to maintain--note the word "good" in the previous sentence.
		Few gravel roads in Alaska are consistently safe for travel at high speed, and where improper materials are used in their construction, or where the footing is stable, such as on bedrock, they are more expensive to maintain than an asphalt pavement.
