Chrysler takes the bad road to make better cars

Article Abstract:

Chrysler Technology Center's test road tracks in Michigan feature simulated severe road conditions to enable engineers to test a car's performance and durability. The track design includes deep water troughs, road bends and slants. It also has two rough road lengths, complete with potholes, raised manhole covers, asphalt breaks and rugged terrain. The main track has banked curves with extreme tilts. Embankments with lower slopes were constructed to avoid damage to the wetlands where the test track was located.

A bumpy road

Article Abstract:

The Wisconsin Dept of Transportation decided to redesign rather than rebuild its geographic information system-based Pavement Management Decision Support System. The system was evaluated according to functional, data, organizational and technology requirements. The department was found to have concentrated too much on the hardware end of the system, while neglecting the people side. In response, the department undertook efforts to improve the flexibility and ease of use of the system.

Diamond blades ease the road-repair grind

Article Abstract:

Highway repairmen in Florida are using grinding methods to break down the tough glacial aggregates on Interstate 10. Grinding will reestablish the road's level profile, facilitate smooth travel, improve road conditions and ensure safety to travellers. Diamond grinding is also cheaper and more durable compered to asphalt overlay. Industrial-diamond saw blades from Wel-Co Metallurgical Corp. were used for the project.
