This study focused on identifying the zero-stress time (TZ) in jointed plain concrete pavements (JPCPs). TZ is the time when the concrete slab is sufficiently strong to deform (thermally expand or contract and thus curl) despite the existing external

Temperature-Moment Concept for Evaluating Pavement Temperature Data

Autor: Mark B. Snyder, Donald J Janssen

Publikováno v: Journal of Infrastructure Systems. 6:81-83

Pavement temperature profile data can be quite useful in the analysis of stresses in jointed concrete pavements produced by temperature gradients within the slabs. Many stress analysis procedures consider the temperature gradients to be linear, thoug

Influence of early age volume changes on long-term concrete shrinkage

Autor: Erika Holt, Donald J Janssen

Publikováno v: Holt, E & Janssen, D J 1998, ' Influence of early age volume changes on long-term concrete shrinkage ', Transportation Research Record, vol. 1610, no. 1, pp. 28-32 . https://doi.org/10.3141/1610-05

Volume changes can occur in concrete during the first 24 hr and are generally missed in laboratory shrinkage evaluations. Unfortunately these early age volume changes are present in real pavements and structures and can contribute to the cracking beh
