Portable Field Scales: A Guide to Features and Selection

Some test methods must be performed on the spot to ensure that the best products are being produced or placed following specified procedures. Portable weighing devices are especially important to operate accurately and conveniently in remote locations. In this blog post, we’ll discuss what to look for when choosing one.

Balanced Mix Design: A New Way Forward

Balanced Mix Design is a practical and common-sense approach to constructing long-lasting asphalt pavements. The design of asphalt mixes traditionally follows a prescriptive, volumetric path. Materials are selected and combined to meet the requirements of the specification with little evidence of what their real performance will be in a localized application or a certain environment. Researchers and practitioners alike have concluded that just mixing the specified ingredients in the stated volumes is a poor predictor of long-term asphalt pavement performance. As one prominent paving engineer put it, “Let’s stop using the recipe to determine if the cake is good.”

Corrosion of Steel Reinforcement in Concrete: Detecting, Mapping, and Monitoring

The corrosion of reinforcing steel is a significant and preventable problem that shortens the useful lifespan of concrete structures. The mechanisms for its development and how it eventually damages the concrete structures it was designed to protect have been well-known for over 100 years. Similar to progressive disease, early detection and monitoring are the most effective strategies to minimize problems. Fortunately, innovative nondestructive instruments are making it easier and more efficient to find, follow, and repair corrosion before extensive damage occurs.

Laboratory Test Sieves: What You Should Know

Test sieves are simple devices, but they are still scientific instruments and the most cost-effective and widely used particle sizing and gradation testing method. This blog article will cover the accuracy verification of sieves, agitation and sieve shakers, accessories, and wet-wash sieves.

Ground Penetrating Radar for Concrete Evaluation: What's the latest?

Ground Penetrating Radar (GPR) is a powerful tool for the nondestructive testing and evaluation of reinforced concrete. Next-generation refinements featured on these versatile new models from Gilson simplify the location and mapping of reinforcing steel bars, tendons, and other embedments while assessing homogeneity, measuring thickness, and detecting cracks, voids, and other discontinuities. GPR units connect wirelessly to Apple iPad® tablets for potent computing power, live 3D and Augmented Reality (AR) rendering, high-resolution display, and fast, easy upgrades. Encrypted Wi-Fi connection stores data in the cloud for instant sharing and collaboration.

Rheology and Viscosity Tests for Asphalt Binder: Methods and Equipment

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.

Soil Sample Preparation: Saving Money in Your Geotechnical Lab

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 Asphalt Permeability, The Methods and Equipment Needed

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.

Concrete Moisture Testing: What Equipment Works for Your Application?

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.
