Description
Documentation and supporting technical notes for a statistical model that estimates changes in the price components of the Colorado Construction Cost Index. The model contains two specifications. In the first, the composite construction index is a function of the producer prices of inputs: oil, concrete, steel, labor and equipment. In the second, the composite construction index is a function of the price of oil, wages and nationwide demand for construction...

The 1983 session of the Colorado General Assembly passed House Bill 1102 authorizing the Colorado Water Conservation Board (CWCB) to conduct a geotechnical study of dam sites in the White River Basin. The objective of the White River Geotechnical Study was to carry out surficial and sub surface geotechnical investigations of the designated dam sites and to locate and evaluate potential sources of construction material. The level of topographic data...

Description
Rural transportation systems are of major importance to the nation's economy. Safety of rural bridges in many cases has deteriorated to a dangerous level rendering many avenues for the movement of goods and people to an unusable state. The recently developed glulam bridge system, composed of laminated stringers and deck fastened together by bolted and doweled connections, offers great potential in needed national bridge replacement programs.

Description
Welcome to CDOT's first web-based Statewide Transportation Plan. This plan is a vision document that outlines what our multimodal transportation options will look like in Colorado over the next 10 to 25 years. It is divided into four sections plus an executive summary, each of which helps to illustrate where Colorado stands today, the challenges that we face, and how we will continue to make progress in the future.

Description
An adequate longitudinal joint tie bar system is essential in the overall performance of concrete pavement. Excessive longitudinal joint openings are believed to be caused by either inadequate tie bar size or spacing or improper tie bar installation. If designed and installed properly, tie bars prevent the joints from opening and consequently improve load transfer efficiency between slabs and between slabs and shoulders, resulting in increased load...
