Accelerated concrete strength study
Accelerated concrete strength study
"The results of the testing of concrete cylinders using three methods of accelerated curing i.e. boiling, constant temperature, and autogenous, indicate that all three methods can be used to predict the 28 day strength of concrete cylinders."--Abstract, Thomas B.

Air pollution at high altitude construction sites
Air pollution at high altitude construction sites
Air pollution is a matter of concern everywhere, but at high altitudes it may have more significance because of the difficulty that some people have breathing rarefied air. Much of the construction in Western states is above the 6,000 foot level, and highways have been constructed above the 14,000 foot level. The results of tests for carbon monoxide, hydrocarbons, nitrogen oxides and particulates at construction sites in Colorado are presented in this report., by Laurence C. Bower and Burrell B. Gerhardt., "For Presentation at the Highway Research Board Meeting, January 1973, Washington, D.C.", Online resource; title from PDF cover (viewed September 2022), Report No. CDOH-P&R-R&SS-72-13.
Asphalt pavement surface sealers
Asphalt pavement surface sealers
This is a report on two asphalt overlay projects that incorporated test sections established for the purpose of evaluating four commonly used surface seals by the Colorado Department of Highways. The seal products evaluated were: 1) reclamite; 2) GSB 78; 3) emulsion (CSS-1h); 4) cut back asphalt cement (MC-70); and 5) gilsabind., Kenneth L.

Clifton-Highline Canal Experimental project I 70-1 (14) 33
The swelling characteristic of Mancos Shale in Western Colorado has caused a great deal of maintenance problems ever since highways were paved. In an attempt to find a method to reduce or prevent this swelling, 19 test sections were included in a contract on IInterstate 70 near Grand Junction. After eight years of evaluation it has been concluded that Asphalt membranes on top of the subgrade and subexcavation and backfilling with an A-4 soil are good solutions to the swelling problem., B.

Colorado tunnel ventilation study
Colorado tunnel ventilation study
Mechanical ventilation of tunnels is costly because of the initial installation and the continued maintenance and operation. However, at some tunnel length corresponding to a particular altitude, traffic configuration and topography there is a need for this forced ventilation. This study was undertaken to help determine the pollution concentration in existing tunnels in Colorado, and predict the length of tunnels which will need mechanical ventilation., Burrell B. Gerhardt [and 3 others]., "Prepared for Federal Highway Administration, Research and Development.", "June 1972.", Includes bibliographical references (page 42)., Interim report, Cover., Report No. CDOH-P & R-R & SS-72-7., Print version record.
