The SR195 highway project connected State Route 195 and US Highway 95, creating a new interstate corridor designed to improve transportation in Yuma, AZ. GTS partnered with contractors and design teams to deliver geotechnical investigations, materials testing, and pavement design support for both Phase I and Phase II of the project.
The project involved:
Our role was to ensure that soil conditions, materials, and construction processes met ADOT, ASTM, and AASHTO standards, providing a reliable foundation for this critical transportation corridor.
GTS conducted extensive construction materials testing on soils, aggregates, and asphalt mixtures. Our services included:
By combining laboratory testing with field verification, we delivered accurate data to guide the project’s construction phases.
Our engineering services went beyond testing, providing actionable recommendations for contractors and ADOT representatives. Deliverables included:
These studies provided contractors and engineers with the data needed to build a safe, compliant, and long-lasting roadway.
The SR195 Phase I & II project was successfully completed, delivering a new interstate connection between SR195 and US 95. With GTS’s support in geotechnical engineering and materials testing, the project achieved:
This project demonstrates GTS’s ability to provide high-quality engineering services across Arizona, supporting transportation infrastructure with precision and reliability.
