Density — Asphalt pavements are constructed and compacted to a specific density as set forth in a contract or bid specifications by mechanically compacting rolling the hot material after it has been placed by the paving equipment. Density is not the same as compaction; density is achieved by compaction. Drainage — A system of drains and pipes for carrying away surface water. An asphalt surface is sloped to maximize the removal of surface water for vehicular safety.

Also, the better drainage a pavement has, the less likely water will seep down into its base. Emulsion — A mechanically produced combination of ingredients that do not normally mix. For example, asphalt emulsions are made by a procedure that mechanically mills the warm asphalt into microscopic globules, dispersing them in water, and adding a small amount of an emulsifying agent. Fog Seal — The process of applying a highly diluted asphalt emulsion in a fine spray fog to a roadway surface.

Fog seals restore blackness and seal hairline cracks, and there is evidence that they help slow or even prevent oxidation. Not generally used for parking facilities due to tracking. Geotextiles — The technical generic name for fabric-like materials used in the paving process.

Geotextiles are manufactured with specific performance characteristics for specific uses such as stabilization of base material to prevent migration into sub-grades. Grade — The degree to which a surface is angled to aid in the drainage of water, the act of leveling or sloping the subgrade or base layer before paving. Heat Lance — Device using a combination of propane and compressed air ignited in a specially designed chamber to produce an extremely hot, directed high-velocity stream of air. Used to remove debris and vegetation from pavement cracks prior to sealing.

A heat lance also warms and dries the crack so it better accepts the sealant. Federal research SHRP H has shown that, when used properly, a heat lance is the most effective preparation method for crack repair. Although more expensive initially, preparing cracks using a combination of routing and a heat lance can provide 10 times the life of conventional crack sealing methods. This term should always be used when specifying asphalt pavement work to avoid any confusion or misinterpretation of the material desired. HMAC is produced in many different grades from coarse large aggregate base mixes to specialized finer aggregate mixes for surfacing and repair.

In most instances the grades are specified according to state Department of Transportation guidelines. For example, if two 8-foot-wide lanes are paved side by side, the joint runs the length of the two lanes. Nuclear Density — Measuring the density of a previously placed material achieved by using a special instrument designed to measure the penetration of radiation into that material.

Reclaimed Asphalt Pavement RAP — Most commonly refers to ground asphalt which is added back into a virgin asphalt mixture at the mixing plant. This and related procedures using RAP are becoming common for economical and environmental reasons. Pavements containing RAP might have different performance characteristics than conventional mixtures.

Larger contracts today should specify if the use of RAP materials is encouraged, allowed, or prohibited. Specialized techniques and materials, such as multi-membrane paving fabrics, help reduce this problem. Slope — The degree to which a paved surface is angled to aid in the drainage of water. Slurry Seal — A high-tech pavement maintenance resurfacing process generally used on streets and roadways.

In this process the slurry sealcoating is manufactured by the application equipment as it is being applied. A closely specified blend of graded asphalt emulsion, additives, and aggregate, slurry seal is generally classified as Type I, II, or III depending on the size of aggregate used. A large aggregate slurry seal with additional polymers may also be referred to as microsurfacing. Rarely used on parking areas due to the potential for tracking in hot weather. Soil or Subgrade Treatment — In some situations the condition of the soil subgrade that will support the pavement is unsuitable for paving.

The soil might be too wet or might simply be unstable so it needs to be treated with lime or with a cement mixture to add strength to create a solid foundation on which to pave. Subgrade — The soil prepared to support a structure or a pavement system. Subgrade Failure — Subgrade failures occur when the prepared soil beneath the asphalt structure can no longer adequately support the weight of the pavement or traffic. Subgrade failures can occur for a number of reasons, including: ground water, too much weight, and inadequate design.

Introduction

Variables such as weather, the amount of traffic, the type of traffic, etc. Tack Coat — Asphalt oil, usually an emulsion type, applied to existing pavement during repairs or prior to overlay paving to create a bond between the old and new asphalt.

More a concern for parking lots than roads. Traffic Index Rating — A measurement of the amount of traffic a roadway or other asphalt surface is experiencing. Transverse Crack — A break in the asphalt pavement that is at a 90 degree angle to the direction of the roadway or the direction in which the asphalt was laid. Transverse Joint — A joint in the asphalt pavement that is at a 90 degree angle to the direction of the roadway or the direction in which the asphalt was laid.

Wedge Cut — The process where the existing asphalt layer is ground in a wedge shape to conform to an adjacent structure such as valley gutter, ramp, or curb and gutter.

What are the "right questions? Happy Halloween! May your day be filled with more treats than tricks! The boundary of the new recycle asphalt surface on Juego Road on Wednesday, November 22, Beginning this summer, crews have layered crushed particles on some of the roadways in the tony rural community southeast of the city.

This is, to hear some of the more apoplectic residents tell it, a grave health risk, an aesthetic abomination, a crime against the community, an environmental catastrophe. Organizers hoped the roadway disputes might be hashed out or a moratorium on new roadway work might be established. But the Nov. And the county jumped to it, with some 15 miles covering more than 30 Eldorado roads on the docket, according to an information sheet posted on the Eldorado community website. Moreno said most residents like the millings, intended for the higher-traffic dirt roadways, and were glad to have better traction and less dust on well-traveled Eldorado streets.

The offending asphalt millings were probably pieces of St. Francis Drive in a past life, Martinez said in August. The ground-up pieces of roadway were awarded free of charge by the Federal Highway Administration, through the state Department of Transportation, for street improvements. These millings can be recycled as a base or finish for another road, and Santa Fe County has been laying them down for more than a decade, Martinez said in the fall.

Eldorado, as has been the case before, is a different story. The great Eldorado chicken fiasco will not be rehashed here.

Yes or no? The Eldorado roads needed the millings, Martinez said.

In the wintertime and summer monsoon season, precipitation sometimes turns the dirt roads to slush, and vehicles can become stuck. Still, Gordon wants them gone; she said the millings are as dusty and slippery as the old dirt roads ever were.
