VOID ALL CHECKS : NEW TEST METHOD ONE OF MANY WHICH SHOULD HELP CONTRACTORS MONITOR PAVEMENT

The Iowa DOT noticed cracking in much of its 1987-poured road concrete and seeks new ways to quantify concrete quality in this article on concrete testing. This article describes a consortium of state DOTs formed to investigate concrete materials and testing techniques in order to ensure long-life, durable concrete pavements. Known as the MCO project, the group released the pooled fund study "Material and Construction Optimization for Prevention of Premature Pavement Distress in PCC Pavements". The results included an air-void analyzer, innovations in mortar sampling, and the purchase of a mobile concrete research lab. The air-void analyzer quantifies air void system volume, size and distribution in fresh concrete. The article describes how a flow-table mortar test came into existence and concludes with a discussion on applications for the mobile concrete research lab.
