Double Wheel Tracker:

To assess the rutting propensity of pavement under wheel load. This involves measuring the pavement’s ability to resist the formation of ruts caused by repeated heavy wheel loads, which can affect the serviceability and safety of the road.

Penetrometer:

To determine the penetration grade of bitumen. The penetrometer measures the depth to which a standard needle penetrates the bitumen sample under known conditions, providing an indication of its softness and ability to flow.

Universal Testing Machine (UTM-25):

To conduct the Resilient Modulus Test and to determine the Tensile Strength Ratio. The Resilient Modulus Test measures the stiffness of asphalt pavements under dynamic loads, while the Tensile Strength Ratio measures the fracture properties of asphalt mixtures, providing critical information for the design, construction, and maintenance of high-quality pavements.

Rolling Thin Film Oven (RFTO)

To simulate the short-term aging of asphalt binders due to exposure to heat and other environmental factors, allowing engineers to evaluate the performance of the asphalt mixture over time and make informed decisions about its suitability for different road paving applications.

Marshall Machine

To formulate the Job Mix Formula (JMF) for a given paving application, which includes the proportions of asphalt binder and aggregates for the mix, and the resulting job mix formula is used to produce consistent and high-quality asphalt pavements.

Softening Point Apparatus

To measure the temperature at which a bituminous material softens and deforms under controlled conditions, providing information on the material’s suitability for different applications.

Rotational Viscometer

To measure the viscosity of the bituminous material at different temperatures and shear rates, which is critical in determining its performance in asphalt mixtures and other applications in the transportation industry.

Los Angeles Abrasion Machine

To determine the resistance of coarse aggregates to fragmentation and abrasion, which is important in evaluating their suitability for use in construction and transportation projects.

Large Capacity Automatic Sieve Shaker

To accurately and efficiently separate and classify different sizes of aggregates used in transportation and construction, in order to ensure they meet the required specifications for their intended use.

Impact Value Machine:

To determine the impact resistance of aggregates used in construction and transportation, which is important in evaluating their ability to withstand sudden impact loads, such as those experienced by road surfaces.

Gyratory Compactor:

To compact cylindrical asphalt specimens to a specific height and density using a controlled and repeatable process, which simulates the behavior of asphalt pavements under traffic loading and environmental conditions.

Flash And Fire Point Apparatus

To determine the lowest temperature at which a bituminous material gives off flammable vapors that can ignite in the presence of an external flame. This information is important in evaluating the safety and potential fire hazards of the material during handling, transportation, and storage.

Flakiness And Elongation Gauges

To determine the shape and size characteristics of aggregates used in construction and transportation, by measuring the percentage of particles that are elongated or flat, which can affect their performance and suitability for specific applications.

Ductilometer

To measure the ductility of bituminous materials, which is the distance a sample will stretch before breaking at a specific temperature and rate of deformation.

Lab California Bearing Ratio (CBR)

To measure the load-bearing capacity and strength of subgrade soils and base course materials used in road construction, by determining the penetration resistance of a soil sample under controlled conditions.

Buoyancy Balance

To determine the specific gravity of aggregates used in construction and transportation, by measuring their mass submerged in water. This information is important for determining their water absorption properties and specific gravities.

Automatic Asphalt Mixer

To prepare and mix asphalt samples with various aggregates, additives, and bituminous materials, using a controlled and standardized process.

Asphalt Binder Analyzer

To establish the asphalt binder content of hot mix asphalt/bituminous mixtures by loss on ignition method. The machine includes a furnace and weighing system that continuously measures the weight of the bituminous mixture during combustion. Through this process, the binder content is automatically calculated at the end of the test.
