This $18M SR 180 East project rehabilitated 3.2 miles of freeway, local street improvements and construction of two bridges. This project was under a Caltrans accelerated schedule which required the project to begin 55 days after contract award. It had to be staged to allow for utility relocations to meet the compressed schedule. The project included Rapid Setting Concrete, Continually Reinforced Concrete Pavement, Hot Mix Asphalt (HMA), stabilized soils and drainage structures.
G3 utilized its onsite mobile concrete laboratory for early age strength testing and performed materials testing and inspection on 69,200 tons of HMA as well as 22,000 tons of Rubberized Hot Mix Asphalt (RHMA). Additional duties included performing Laydown inspection, monitoring compaction, and coring the HMA for densities during each day of production of HMA and RHMA. We also performed laboratory testing which included theoretical max densities, core densities, testing for air voids, Hamburg, and Tensile Strength.
