Asphalt Testing Equipment

Called asphaltic concrete, bituminous concrete or just asphalt, it is the most widely used construction material for development of paved roads. Using asphalt bitumen as a binder, along with fine and coarse aggregates, mix designs are formulated in the lab, then carefully tested to produce hot-mix asphalt for a wide variety of paving applications. Performance of asphalt pavements must continuously improve to meet the demands of today’s transportation infrastructure.

Asphalt Testing Equipment

Modern asphalt pavements must resist rutting, thermal variations, high load cycles, hydraulic pressures from water, and more. Testing asphalt for characteristics such as air void content, density, shear strength, stiffness and fatigue resistance provides assurances that this construction material is up to the task.

Producing pavement mixes with long life and low maintenance costs begins with extensive testing in the lab. Aggregates, binder types, and additives are evaluated separately before finding the correct proportions for blending. Once a suitable mix design has been established, quality control and quality assurance testing guarantees installation of a quality pavement.

Gilson's complete line of asphalt testing equipment offers an extensive selection of products for testing asphalt binder, hot-mix asphalt aggregates and pavement quality. using both Marshall and Superpave® design methods.

  • Asphalt Mix Design – This is the process of designing a complete paving mixture to meet the needs of a specific project using popular methods such as Marshall or Superpave®. This includes selection and proportioning of aggregates, asphalt bitumen and additives. There may be unique requirements for rut-resistance, wear-resistance, aggregate type, or temperature performance. Gilson offers a variety of items for Marshall testing, Superpave design, Asphalt Extraction, and more. Popular products include our Asphalt Binder Ignition Furnace, Hamburg Wheel Tracker, and the Gilson QuarterMaster Asphalt Sample Divider.
  • Asphalt Binder Testing – Encompasses a variety of tests to evaluate properties of the bitumen, or binder fraction of the paving mix that will affect performance of the hot-mix product. Equipment for asphalt viscosity, softening point, penetration resistance, ductility, and asphalt bulk specific gravity includes Rolling Thin Film Ovens, Bending Beam Rheometers, Pressure Aging Vessels, along with Brookfield Rotational Viscometer/Rheometers and Dynamic Shear Rheometers.
  • Pavement Quality Testing – The final step in testing begins with laydown of the hot-mix asphalt mat. These tests ensure that quality control requirements are met. Gilson features FLIR® Thermal Imaging Systems, making it easy to monitor and visually record asphalt properties during paving operations. Core Drilling Machines with Diamond Core Bits, NCAT Asphalt Field Permeameters, and Benkelman Beams allow complete evaluation of the finished pavement.

Gilson’s family of asphalt testing equipment offers the widest range of products with the performance, features, and capacities you require. Gilson equipment meets your needs for fast, accurate, and reliable material analysis, compliant with ASTM and AASHTO standards.
