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

• The equipment is in accordance with EN 12697-1, EN 13108
• Centrifuge is designed for proper separation of the filter quickly without fillers or binders containing suspended sediment mixtures

• Solution is poured into a funnel and falls in container dia test. 70x200mm that rotates, due to centrifugal effect, the liquidrises vertically, leaving the pot filler and mineral particles
• The centrifuge is supplied complete with aluminum tank, two sites of 2mm and 0.063mm

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.
