Asphalt binder is a fundamental and surprisingly complex component in the design of modern asphalt pavement mixes. Of the many properties of bitumen that affect its performance in a modern asphalt paving mixture, two are crucial to the long-term success of pavements, viscosity, and rheology. This blog post will explore binder viscosity tests and rheology tests, their applications, benefits, and testing equipment.

With a little thought and planning, you can avoid duplicating the equipment needed to perform many sample preparation tasks. Many ASTM and AASHTO soil tests performed follow similar techniques and use the same or similar equipment to set up samples for your soil testing.

Measuring the permeability of asphalt mixes is a powerful tool to predict and improve the service life of flexible pavements. In this blog post, we will discuss methods and the testing equipment needed for two basic asphalt permeability tests to mitigate pavement problems over the long term.

The amount, type, location, and movement of moisture in a concrete slab need to be clearly understood to avoid problems when placing a flooring system over it. In this blog, we take a look at the various methods and equipment to use for testing concrete for moisture.

In this blog post, we focus on the specialty large volume splitters. These sample dividers you may not see every day. They have unique features that could solve a problem for you when sample dividing coarse aggregates.

This blog post will focus on the core drilling method and the core sampling equipment. We discuss why and how core samples are taken from asphalt and concrete. Lastly, we touch on some of the different lab tests performed.

In this month's blog post we discuss the equipment and procedures that are used to perform the ASTM and AASHTO test method for Specific Gravity of Soil Solids.

Does the particle size analysis of coarse aggregates always require a testing screen with large screen trays? In a situation where larger testing equipment is not available, there may still be ways to get the job done. Using conventional round test sieves for large particle sizes is less efficient, but still acceptable if done properly. We discuss test requirements, sieve capacities, and tips to help with equipment selection.

Advances in technology continue to refine concrete cover meters and rebar locators, which have been around for decades and used to locate and identify concrete reinforcing steel accurately. They are integral to nondestructive evaluations of reinforced concrete structures and pavements to prevent damage to the reinforcing steel within the structure when drilling or cutting reinforced concrete. This blog post explores the features and capabilities of some of these popular instruments.

This blog provides an informative guide on why direct shear testing is essential, and we guide you on what equipment you need to perform the test based on ASTM D3080 and AASHTO T 236.
