This dual purpose oven is designed to determine the loss in weight of bitumen and flux oils (Loss on Heating test) and the effect of heat and air on asphaltic materials (Thin Film test). The unit is heavily insulated and has a double glass door for viewing the test chamber thermometer and samples. Temperature is controlled at 163° C ± 1° C by means of a variable temperature controller and thermostat. Two rotating platforms are supplied with each oven: One accepts 9 standard penetration cups for the loss on heating test, the other accepts two140mm diameter test pans for the thin film test. The platforms are rotated at 5 to 6 rpm by an external motor.

The Semi-Automatic Penetrometer for Liquid Limit consists of a cast iron base with coarse and fine leveling screws, a digital penetration measurement gauge 0.01 mm resolution/readability and an automatic penetration timer unit. The is equipped with a digital, 99 second timer, which can be set to the standard 5 second free-fall time or to some other setting for customized tests. When engaged the timer will allow the needle to free fall into the sample for the specific time interval and then lock the needle from advancing while providing a direct reading of the test results.
320 g weight should be added to the 30° angle cone to get a total weight of 400 g for the shear strength test.

The super pave PG binder specification looked for tests which would closely simulate field performance. Hotmix asphalt binder experiences significant aging during the manufacturing and laying process. Investigating this phenomenon within a laboratory environment, with a repeatable and simple test is very useful within the design process. The rolling thin film oven (RTFO) test is used to measure the effect of heat and air on a moving film of semisolid asphalt binder. The results of this treatment are determined from measurements of the binder properties before and after the test. Repeatability of the test is directly related to the accuracy with which the oven temperature can be maintained and the reproducibility of the thermal rise time of the system. Super accurate P.I.D. Controller.

The Automatic Compactor For Bituminous Mixes eliminates the laborious process of manual compaction and an even degree of compaction is achieved. The driven mechanism lifts the weight of 4.5kg and drops it through a correct height of 457 mm. The rammer foot is removable, which facilitates preheating. A compaction pedestal with specimen holder is fixed to the base. An Automatic Blow counter enables the number of blows to be present before each test and automatically stops the machine on completion.

The Automatic Electronic Penetrometer is used for determination of the needle penetration according to EN 1426, ASTM D5 and AASHTO T49 standards. The penetration depth of the needle is determined with a pulse type electronic measuring system, which is separated from the plunger during the test, this allows the free guidance of the plunger which virtually eliminates friction during the test. Before each start of the test the measuring system automatically resets, and then the penetration needle moves down to the sample by using the electric drive, the needle position can be finely adjusted by using the joystick located on the front panel. A magnifying glass and an ultra- bright LED lamp are supplied to assist the operator; the plunger is then automatically released onto the sample and raised automatically after the testing period. The test result is displayed on the digital display. The plunger can easily be removed to calibrate its weight.

The Automatic Electronic Penetrometer is supplied complete with:

• Penetration Needle, 1 piece
• Transfer Dish
• Sample Cup, 55x35 mm, 6 pieces, stainless steel
• EN 1426; ASTM D5; AASHTO T49

We are the manufacturer of PRD Mould BS 590:10. This mould, vertically split on one side foreseen of clamp attachment to the box plate. Plated against corrosion, is utilized for determining the degree of compaction of Bituminous pavements for quality control purpose.
