Syed, A and Sonparote, R S (2020) Development and early-age performance of an innovative prestressed precast concrete pavement. Journal of Construction Engineering and Management, 146(2): 05019018, ISSN 0733-9364
Abstract
Use of precast concrete pavement (PCP) for rapid construction of roads has gained high popularity in the last decade. In this technology, precast pavement panels are cast in a precast yard, transported to the construction site, placed on a prepared subbase, and connected using dowel bars. This paper describes one such application, reported for the first time in India. Planning, analysis, design, construction, and testing of a 24-m road length was discussed. An empirical equation was developed to obtain the stresses induced in the panel. It also includes an innovative load transfer mechanism (LTM) using a lateral dowel bar arrangement instead of the commonly used longitudinal dowel bar arrangement. This LTM is easier to implement, helps to maintain good riding quality, provides faster construction speed, and does not compromise the load transfer efficiency (LTE). The load transfer efficiency of the newly developed LTM was found to be 97% 6 months after placement of the panels.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
