On Friday, April 17, 2015, Project Cornerstone's Crystal Howard and Alyssa Burley, along with Granite Construction's Gary Nolan, visited two sixth-grade classes and a 5th/6th-grade combination class at William H. Frazier Elementary School in Fallbrook, CA.

The students learned about the importance of construction aggregates in their daily lives and where they are mined locally in their community.

They performed a sieve analysis by testing two aggregate samples.  One included river sand and the other included beach sand.  As expected, the students determined river sand is best suited for making concrete.

Students made small batches of concrete using sand, gravel, cement and water.  They added pigment to give their concrete mixtures color before pouring it into molds to make concrete butterflies, ladybugs, footballs, trucks and more!

Granite Construction Spotted at the Airport

Written by Alyssa Burley.

Granite Construction Company, one of the largest diversified heavy civil contractors and construction materials producers in the United States and Project Cornerstone supporter, was spotted laying asphalt at the San Diego International Airport on Friday, February 13, 2015.

Asphalt is made from construction aggregates (i.e., sand, gravel and crushed stone) and asphalt cement.  It's durable and 100% recyclable.

  • Of the 2.27 million miles of paved roads in the US, 94% is surfaced with asphalt, including 65% of the interstate system.
  • The U.S. recycles about 2 million ton of plastic a year while recycling and reusing over 60 million tons of asphalt.
  • Research in the U.S. and Europe shows that quiet asphalt reduces highway noise by 3 to 5 dB(A) and more.
