The objectives of the research were to evaluate the use of zero-length vertical curves with respect to TxDOT design practice, construction results, vehicle dynamics, and accident history, and to compare zero-length vertical curves to minimum design vertical curves (as specified by TxDOT). Researchers determined use of zero-length vertical curves using a questionnaire distributed to TxDOT personnel in all 25 districts. Seventy-one percent of the respondents had used zero-length vertical curves. In this study, 20 zero-length vertical curves and 15 minimum-length vertical curves were evaluated. Constraints limited grade change for the vertical curves to a maximum of two percent. Evaluation included surveying the roadway profile, measuring vertical acceleration, and investigating accident information. The results showed that: sight distance is not applicable to sag curves with grade changes below two percent and is applicable to crest curves with grade changes above 0.5 percent and design speeds over 100 km/h; below 0.5 percent grade change, comfort criteria for zero-length and minimum design vertical curves did not exhibit any practical difference; between 1.0 and 0.5 percent grade change, comfort criteria showed unacceptable performance for high speed tests; zero-length vertical curves were more likely to meet drainage grade requirements than were minimum design vertical curves; and accident studies did not reveal any apparent relationship to the type of vertical curve.

In road projects, the pavement construction is very expensive and, therefore, the design and subsequent construction must make a proper balance between the cost and the sustainability. During the operation and maintenance period, the costs for routine maintenance (as and when pavement damage occurs) are to be kept as low as possible as there is less control towards cost of the periodic maintenance (mandatory at a contractual interval, normally 5 years). The reduction in cost for routine maintenance will relieve the project authorities from unexpected expenditures. This comprehensive text on Pavement Engineering is up-to-date with industry standards and best practices and offers an exhaustive coverage on design, construction and maintenance of pavements. The book has followed AASHTO Guide for Design of Pavement Structures, 1993, besides meeting latest code provisions and pavement design methods recommended by Indian Roads Congress (IRC) and Bureau of Indian Standards (BIS). This book has all standard topics on the subject, but differs from all other books in respect of following contents: • Pavement Engineering and Highway Geometrics • Design of Flexible Bituminous/Asphalt Pavement • Design of Rigid Concrete Pavement • Construction of Flexible Bituminous/Asphalt Pavement • Construction of Rigid Concrete Pavement • Maintenance of Flexible Bituminous/Asphalt Pavement • Maintenance of Rigid Concrete Pavement • Maintenance of other Road, Drainage and Bridge features This book refers to the web uploaded volume ‘User’s Guide for Computer Applications’ at web site www.roadbridgedesign.com to help readers learn various computer applications in pavement engineering. This book is designed to serve as a textbook for undergraduate and postgraduate students of Civil Engineering, Highway Engineering and Traffic and Transportation Engineering. TARGET AUDIENCE • BE/B.Tech, ME/MS/M.Tech (Civil Engineering and Transportation/ Highway Engineering) • Professionals of Highway/Road Construction Industry
