CMI Roadbuilding, Inc. of Oklahoma City began in 1961, when engineers headed by Bill Swisher started looking for new methods in the road building industry. Little had changed since the early 1900s in the methods of building roads, however, labor costs were skyrocketing and inflation meant taxpayers dollars were buying less and less.
Sit harness. A climbing harness is a piece of equipment that allows a climber to tie in to the safety of a rope. [1] It is used in rock and ice climbing, abseiling, and lowering; this is in contrast to other activities requiring ropes for access or safety such as industrial rope work (such as window cleaning), construction, and rescue and recovery, which use safety harnesses instead.
The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering [1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage. This method provides little indication of ...
Rope access or industrial climbing or commercial climbing, is a form of work positioning, initially developed from techniques used in climbing and caving, which applies practical ropework to allow workers to access difficult-to-reach locations without the use of scaffolding, cradles or an aerial work platform.
In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3 ⁄ 8 in), with smaller gauges designated cable or cords. [1] Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure.
Gel-Nimbus 25. With soft, cloud-like gel cushioning in the midsole, the Asics Gel-Nimbus 25 shoes have the stamp of approval from Anne Sharkey, D.P.M., a podiatrist at North Austin Foot & Ankle ...
Rigid barriers such as concrete and semi-rigid barriers such as steel guardrail, exhibit impact deflections of 0 to 4 ft (1.2 metres), respectively. [1] Flexible systems such as cable barriers deflect between 8 and 12 ft (2.4 and 3.7 metres) upon impact.
