Artículo:: MnROAD Jointed Concrete Pavement Test Sections
Resumen:: The Minnesota Department of Transportation (MnDOT) opened the Minnesota Road Research (MnROAD) facility in Albertville, MN, in 1994. By 2008, interest in examining more current pavement designs led to the reconstruction of some test sections. To extract as much useful information as possible, a comprehensive forensic investigation was conducted during the removal of the original sections. This article presents some of the findings, with particular focus on unusual degradation of transverse joints

Artículo:: Mitigating Alkali-Silica Reaction when Using High-Alkali Cements
Resumen:: When adequately mitigated, alkali-silica reactive aggregates can be used in concrete, but testing potential mitigation measures may require significant lead time. An alternative approach, CSA A23.2-27A, “Use of Supplementary Cementing Materials for Counteracting Alkali-Silica Reaction,” incorporates long-term performance data from laboratory prisms, outdoor exposure tests, and structures. It limits maximum alkali contents of concrete and minimum dosages of supplementary cementitious materials for use with known reactive aggregates. CSA A23.2-27A was introduced in 2000 and updated in 2004 and 2009. It’s the model for the new AASHTO PP65, and it will serve as a resource for the new ASTM Subcommittee C09.50 on Risk Management for Alkali-Aggregate Reactions
