Book Description
In the fall of 1984, the Kansas Department of Transportation constructed a project involving cracking, seating, and overlaying a portland cement concrete pavement. The project is located in Wyandotte County on K-7 highway, north of K-32. This project is on the west side of the Kansas City metropolitan area. Eight experimental sections and one control section were stipulated for this project. One section of regular construction was selected for the control section. Four of the eight test sections were designated to be cracked at 0.9 m (3 ft) centers, and the other four were cracked at 1.5 m (5 ft) centers. One half of each spacing pattern was saw cut at the quarter points of the 18.7 m (61.5 ft) panels [approximately 4.6 m (15 ft) spacing, minimum 127 mm (5 in.) deep, maximum 13 mm (0.5 in.) wide] prior to cracking. Four sections had minimal joint repair; four had normal joint patching. There have been no easy determinants as to why the transverse cracking is low in some sections, and high in others. In some years it appears to be one factor, but the next year the factor has appeared to change. After 10 years there is no difference attributable to the cracking spacing, probably because both spacings are too large to adequately distribute the thermal movements. Slightly better performance was noted in sections that have minimal joint patching. More recent projects have used rubblizing as a rehabilitation technique. These have not shown significantly better performance than the cracking method. More investigation needs to be done to quantify the effect of various components that are used in this technique.
Failure and Repair of Continuously Reinforced Concrete Pavement

Book Description
The performance of CRCP has revealed a number of failure modes that are traceable to design, construction, materials, and maintenance deficiencies and such other factors as environemntal conditions and traffic loadings. This report of the Transportation Research Board includes a review of the cumulative experiences of state that have constructed and maintained CRCP. Guidelines for repair techniques are included, and areas of needed research are identified.
Repair of Concrete Pavements

Pages : 142
Book Description
Paper 1 evaluates the use of welded wire fabric reinforcement to alleviate rutting and/or shoving of pavement at intersections, and compares the effectiveness of extra thickness of asphaltic concrete overlays over portland cement concrete vs the use of welded wire reinforcement in the asphaltic concrete overlay to control reflection cracking in the asphaltic concrete surface. Paper 2 concerns a method of controlling reflection cracks in bituminous concrete overlays over the transverse joints of rigid pavements. Paper 3 concerns the experiences in district no. 4 of the New York State Department of Public Works with the salvage and restoration of old concrete pavements. Paper 4: Maintenance programs during the first 8 years of commercial airline operation at Willow Run Airfield are described.
Proceedings of SECON’21
Author: Giuseppe Carlo MaranoPublisher: Springer Nature
ISBN: 3030803120
Category : Technology & Engineering
Languages : en
Pages : 1127
Book Description
This book gathers peer-reviewed contributions presented at the International Conference on Structural Engineering and Construction Management (SECON’21), held on 12-15 May 2021. The meeting served as a fertile platform for discussion, sharing sound knowledge and introducing novel ideas on issues related to sustainable construction and design for the future. The respective contributions address various aspects of numerical modeling and simulation in structural engineering, structural dynamics and earthquake engineering, advanced analysis and design of foundations, BIM, building energy management, and technical project management. Accordingly, the book offers a valuable, up-to-date tool and essential overview of the subject for scientists and practitioners alike, and will inspire further investigations and research.
