Analysis of stress relaxation in jointed plain concrete pavements

Smoothness variations in early-age jointed plain concrete pavements

This paper discusses the variations in the early-age pavement smoothness at different measurement times and locations in three jointed plain concrete pavements ( JPCPs) representing different ranges of construction times. Surface profile measurements were made during the early morning and late afternoon hours at different locations of the instrumented JPCPs during the first 7 d after constructi...

Environmental Effects on Deformation and Smoothness Behavior of Early-Age Jointed Plain Concrete Pavements

In this paper, a study of environmental effects on the deformation and smoothness behavior of jointed plain concrete pavement ( JPCP) during its early age is presented. A newly constructed JPCP on US-34 near Burlington, Iowa, was instrumented and monitored during the critical time immediately following construction to identify its early-age behavior regarding temperature variations. The surface...

Best Practices for Jointed Concrete Pavements / Blended Aggregates for Concrete Mixture Optimization Tech Brief

INTRODUCTION Historically, aggregate gradation has been controlled by specifications that call out envelopes for individual fractions, typically the coarse aggregate and the fine aggregate. The shortcoming of this approach is that the gradation of the overall system is not addressed. While it is sensible to stockpile coarse and fine fractions separately to prevent segregation, it is the combine...
