A review of full-depth reclamation of pavements with Portland cement : Brazil and abroad

Abstract

This paper presents a literature review of full-depth reclamation of pavements with Portland cement (FDR-PC). The paper consists of the following topics: history, construction steps, advantages and disadvantages, mix design, structural design, and behaviour in the laboratory and the field. All sections provide comparisons between international and Brazilian experience. The paper highlights that FDR-PC is used worldwide with significant benefits. While mix design methods are well-established internationally, structural design methods still need to be adapted in most countries. The paper presents ranges of strength and stiffness values based on previous research. Analysis of previous research also identified a suitable test for field modulus prediction and general effects of some characteristics on the behaviour of FDR-PC materials. Furthermore, it identified knowledge gaps for future research, which could promote FDR-PC application with confidence.
