Recarpeting using cement grouted bituminous mix in urban flexible pavement: a laboratory and field evaluation
Cement Grouted Bituminous mix (CGBM) mix is a semi-flexible pavement type that essentially is an open-graded bituminous mix grouted with cement mortar comprising the advantages of both flexible and rigid pavements. CGBM is not popular and widely adopted in India so far may be due to a lack of available performance studies imparting knowledge. Therefore, an attempt has been made in this study to prepare grouting material and develop the mix design consideration first. Further, CGBM characteristics as an alternative recarpeting and/or wearing course material in the Indian scenario based on laboratory and field evaluation in comparison with bituminous concrete mix that is conventional wearing course is explored. In this regard, a trial stretch of CGBM is constructed in the urban area, and field performance is ensured with the laboratory results. Test results reveal that the CGBM mix possesses higher Marshall stability, compressive strength, tensile strength, resilient modulus, better resistance against the moisture damage and oil spillage condition, and less temperature susceptible than the conventional bituminous concrete mix. This case study of CGBM overlay is substantially increasing the remaining service life of the pavement in terms of fatigue and rutting life.
