Last month there were several updates to standards involving texting the flexural strength of concrete as well as updates to some masonry and dimension stone standards. ASTM D6926 – Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus has been updated, so if you are involved in asphalt pavement testing, make sure you go and find out what the changes are. There are also a whole slew of groundwater and site investigation standards that were reapproved.

The “breakthrough” media event for CALTRANS’ Devil’s Slide Tunnel project was this past Friday. A large crowd of politicians, news crews and locals were on hand as a road-header broke through a shotcrete face in a ceremony to mark the completion of the excavation portion of the first of two tunnels. It will still be over a year until the tunnels are opened to traffic. The second tunnel is expected to breakthrough as early as this week. (Photo by SFGate.com)

On September 30, 1935, President Franklin D. Roosevelt dedicated the Hoover Dam, telling the 10,000 people gathered at the ceremony that it was a “great feat of mankind” destined to reshape “the geography of a whole region.” The American Society of Civil Engineers calls it one of the “Seven Modern Civil Engineering Wonders.” In honor of this significant milestone for this fantastic structure, I’ve collected some facts and figures, news articles, information on the bypass bridge, and some concerning news about the future of the dam’s ability to supply power.
