	Item 740 Pavement Marking Material
		Pavement marking materials prequalified by a service test may be tested by the Laboratory to determine formulation compliance to prequalified material and compliance with physical properties specified herein.
		The marking material shall be delivered in containers which are clearly marked to indicate the number of liters (gallons), weight or size of material, material color, batch number or other similar manufacturer's identification, date of production and the company name and location.
		After pavement application in accordance with the manufacturer's recommendations, at a thickness of 3 to 5 mm (0.125 to 0.188 inches), the material shall dry to a no-tracking condition in not more than two minutes at a surface measured temperature of 10 C (50 F).

	Pavement (material) - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-01)
		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.
		The material is applied in a freshly-mixed slurry, and worked mechanically to compact the interior and force some of the thinner cement slurry to the surface to produce a smoother, denser surface free from honeycombing.
		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 in some countries typically only maintained for historical reasons, while in other countries they are still common in local streets.

	Reclainmed Asphalt Pavement - Material Description
		Reclaimed asphalt pavement (RAP) is the term given to removed and/or reprocessed pavement materials containing asphalt and aggregates.
		Studies on pavements in California, North Carolina, Utah and Virginia have shown that before and after milling, the pavement fraction passing a 2.36 mm (No. 8) sieve can be expected to increase from a premilled range of 41 to 69 percent to a postmilled range of 52 to 72 percent.
		This is due primarily to exposure of the pavement to atmospheric oxygen (oxidation) during use and weathering.

	PolyPavement: Natural Soil Pavement - Liquid Soil Solidifier
		With PolyPavement, the existing in-place soil or a suitable imported soil is used for 98% of the pavement construction material.
		Approximately 350 other methods and materials were also tested by the Corps of Engineers.
		No other material performed as well as PolyPavement and no other material had equivalent versatility, easy installation or as low a cost.

	Pervious Concrete Pavement Design for Sustainable Porous & Permeable Stormwater Drainage
		Pervious concrete pavement is a unique and effective means to address important environmental issues and support sustainable growth.
		water and cementitious materials are used to create a paste that forms a thick coating around aggregate particles.
		This site focuses on the pavement applications of the material, which also has been referred to as porous concrete, permeable concrete, no-fines concrete, gap-graded concrete, and enhanced-porosity concrete.

	Concrete Pavement Fundamentals (Site not responding. Last check: 2007-11-01)
		They may be designed for a life of 5, 10, 20 and even 50 years, a range that far exceeds what is possible with any other pavement material.
		As a result of the versatility and the range of features, not all concrete pavements are alike.
		This is certainly evident when comparing the pavements designed by state Departments of Transportation and other design and specifying agencies.

	Study of In Situ Pavement Material Properties Determined from Falling-Weight Deflectometer Testing
		While the Guide provides one of the most widely used empirical design models for flexible pavement design, a factor complicating its utility is the use of an abstract quality, the structural number (SN), to quantify the strength of the total pavement structure.
		A consequence of the SN is the need for structural layer coefficients (ai) to characterize the component materials of the pavement structure.
		However, the Agency has developed and tested a method for determining layer coefficients using a falling weight deflectometer (FWD), and the resulting layer coefficients are representative of the in situ behavior of the pavement materials.
