The Nevada Department of Transportation (NDOT) is the latest state agency to approve the use of portland-limestone cement (PLC) on new highway construction projects in an effort to reduce its carbon footprint, reported local media.
In Nevada, transportation contributes 35% of the state’s total greenhouse gas emissions. NDOT anticipates that the use of PLC in highway paving projects will reduce carbon dioxide emissions by approximately 4,000 tons per year.
Annually, NDOT uses about 45,000 tons of cement to build, maintain and upgrade pavement, bridges, sidewalks, curbs, retaining walls, culverts, and more.
The transportation agency worked with industry experts and stakeholders, such as the Nevada Associated General Contractors and California Nevada Cement Association, to draft the new standards.
