as recording secretary for 09.60 and 09.40.
He serves as NRMCA’s representative on the FHWA Concrete Pavement Technology
Program Engineering ETG (Task 65), Performance Specifications ETG, Mixture
Optimization ETG, PCA’s Product Standards and Technology Subcommittee and
other technical committees as pertinent to the goals of the NRMCA.
Colin has coordinated and reported on research activities at NRMCA related
to measurement of water content in fresh concrete, use of wash water in
ready mixed concrete, effects of reuse of returned concrete on concrete
properties, testing high strength concrete and cores, alkali silica
reactivity tests, reuse of returned concrete, maturity of high volume fly
ash concrete, concrete durability research and several smaller research
