Previously, G3 went into detail about LCA and EPD Sustainability, explaining what they are and when and how they will affect the construction industry. Let’s take a closer look at the laws that require these changes and the effects these laws will have. State and federal laws are being changed … Read More
Drying shrinkage is a change in the volume of a hardened concrete mixture due to the loss of moisture. Drying shrinkage testing is performed to determine the length changes of a hardened concrete mixture caused by loss of moisture. With this test, the effects of different mix designs on free … Read More
California and the Federal government have been pushing legislation to help decrease the number of carbon emissions (Federal “Buy Clean” Initiative and California’s AB 2953) and Global Warming Potential (GWP) of construction projects. These bills and legislations will affect the engineering industry including contractors which means as an industry we … Read More
There is a new section in Section 40 of the 2018 (RSS) October 2021, that will free the contractor from the variability of modulus of rupture (MOR) flexural beams and reduce disputes for early opening to traffic. Section 40-1.03L now gives the contractor an alternative to MOR testing, by following … Read More
California is one of the leading states with commitments from all parts of every industry to strive to reduce the carbon footprint and Co² in the next 30 years. The construction industry is very much a part of this movement with individual materials that make up concrete and asphalt being … Read More
Road smoothness requirements are written into all Caltrans interstate and state highway projects. Contractors are held to high standards to achieve road smoothness tolerances. When pavements are smooth it reduces emissions, reduces vehicle wear and tear, and roads last longer. State DOT’s and government agencies also hear less complaints about … Read More
The above blog title is the most frequently asked question I am receiving from contractors as of late. Since the revised standard specifications (RSS) addition of compressive strength cylinders for concrete pavement acceptance, I am being asked, do we still need to make flexural beams? The quick answer, it depends … Read More
A generational $1.2 trillion infrastructure plan was put in place to give the country a much-need economical boost having faced one of the worst global crises in modern history due to the Covid-19 pandemic. While legislators hope for the bill to help with inflation and supply chain struggles, industry experts … Read More
In this blog, we will establish an old concept not regularly used in concrete pavement. The use of “Maturity to Determine Opening to Traffic Concrete Strength.” This new section 40-1.03L in October 2021, 2018 Revised Standard Specifications (RSS), is completely new to the Caltrans construction process but is an old … Read More
The Friant-Kern Canal is a 152-mile-long waterway that extends from the Friant Dam at Millerton Lake north of Fresno to the Kern River in Bakersfield. The original canal, built-in 1951, was designed to convey up to 5,000 cubic feet per second (CFS) of water to over 1 million acres of … Read More
