Utility Repair Tag
Utility repair tag (also known as A-tag, asphalt tag and road cut medallion) is a plastic color-coded pavement marker embedded in the top surface of an asphalt utility cut restoration to identify the responsible party of that pavement repair or patch. The tag is not to be used for identification of an underground utility location. History In 1987, a patent application was filed by Richard E. Sanchez to create a flat disc plastic wafer to be used as a utility cut patch identification tag. Prior to that, government regulations required identification Washer (hardware), washer to be nailed into the pavement, which created many issues. Subsequently, Sanchez made an improvement to add legs to the plastic disc and filed for another patent in 1989. However, the invention was not used for its intended purpose. The tags were used by many municipalities as call before you dig warning markers instead. In 2006, New York City Department of Transportation initiated its A-tag program. The goal w ...

Utility Cut
A utility cut is a cut and excavation to an existing road surface to install or repair subterranean public utility conduits and equipment. After the utility is installed or repaired, the road needs to be restored which will result in patches on the road surface. Due to a different settling rate of the backfill material relative to the original pavement, the road surface condition may be deteriorated after the road restoration. This will require ongoing maintenance and repairs. Some municipalities require contractors to install utility repair tags to identify responsible parties of the deteriorated patches.

Radio-frequency Identification
Radio-frequency identification (RFID) uses electromagnetic fields to automatically Automatic identification system, identify and Tracking system, track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an Identifier, identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the Line-of-sight propagation, line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer Propene, propylene. Polypropylene belongs to the group of polyolefins and is Crystallization of polymers#Degree of crystallinity, partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial producti ...

Sanitary Sewer
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage. Sanitary sewers serving industrial areas may also carry industrial wastewater. In municipalities served by sanitary sewers, separate storm drains may convey surface runoff directly to surface waters. An advantage of sanitary sewer systems is that they avoid combined sewer overflows. Sanitary sewers are typically much smaller in diameter than combined sewers which also transport urban runoff. Backups of raw sewage can occur if excessive stormwater inflow or groundwater infiltration occurs due to leaking joints, defective pipes etc. in aging infrastructure. Purpose Sewage treatment is less effective when sanitary waste is diluted with stormwater, and combined sewer overflows occu ...
