Superpave’s origins came from simple questions that ballooned into complex, numerous offshoots as time passed and funding permitted. In this blog post, we discuss the impact of Superpave from the perspective of mix design, construction materials testing, and equipment for the lab.

A multilayer asphalt design must perform as a single unit to withstand heavy traffic loads. In our latest blog, we’re taking a look at how asphalt tack coat is used to strengthen pavements, and how shear strength is tested to ensure optimal performance.

A basic load frame offers flexibility to become a multi-functional testing apparatus simply by adding or removing individual components designed for specific soil tests – and your testing needs. This blog post explores what to consider in determining the right type of load frame, as well as components and fixtures to select from that, can adapt it for different tests and ensure efficiency in the materials testing lab.

The Asphalt Rice Test is commonly used in determining theoretical maximum or asphalt specific gravity in accordance with ASTM and AASHTO standards. This blog post covers what you should know about the test and equipment available to help ensure testing in compliance with ASTM D2041 and AASHTO T 209.

Over the past several months, we have explored various materials testing technician certifications and what it takes to achieve them. This final summary blog in the series includes what’s new, schedules for 2018 programs and testing, and a downloadable PDF Resource List. As any additional information becomes available, we will update the blog series accordingly.

Gilson continues its series of blog posts on what to know when preparing for and taking a technician certification exam. This third post covers asphalt technician certifications, and includes information and resources designed to help you with the process.

An ever-increasing number of regulations, project requirements and even individual test methods require that laboratory and field personnel undergo specific training and pass certification examinations before they can perform certain tests for the record. This, and the wide array of training and certification programs available from different organizations, underscore the importance that the engineering and construction communities place on expertise, competency and accuracy in all areas of construction materials testing.
