Automatic mixer is an indispensable mixer when preparing asphalt-sand-stone mixture or cement-sand-stone mixture samples. At present, it has been widely used in laboratories of scientific research, construction and supervision departments of highway systems.

The aggregate impact tester is used to determine the impacting times, to assess. The performance of resisting temporal impacting or vibrating for all kinds of aggregate,(including coarse or thin aggregate material).

The density of asphalt pavement is directly proportional to the dielectric constant of the measured material.The gtj-2701 USES an innovative, spiral-shaped magnetic field detector to test the dielectric constant in the presence of a magnetic field generated by the sensor plate. The electronic components of the gtj-2701 convert the field signal into a material density reading displayed on the screen.Once the instrument is calibrated, the density can be read at once.

GD-0334 ASTM D2419 Sand Equivalent Apparatus is designed and made as per T 0334 Sand Equivalent Test for Fine Aggregate in JTJ 058-2000 Specification and Test Methods of Aggregate for Highway Engineering. GD-0334 ASTM D2419 Sand Equivalent Apparatus is used to determine the cohesive soil content or impurity content in fine aggregates. The sand equivalent is expressed by SE. The maximum particle diameter shall be less than 4.75mm(The diameter of the sieve is 5mm).

Used in conjunction with a suitable electronic balance for specific gravity determination of fresh and hardened concrete and aggregates. A purpose built robust frame designed to support the electronic balance.The lower part of the frame incorporates a moving platform, which carries the water container allowing the test specimens to be weighed in both air and water. The balance is included in the apparatus. Any type of electronic balance fitted with an under-bench weighing facility can be used. The diameter of the stainless steel mesh basket is 200mm, and the mesh is 3.35mm, it also can be customized.

The Thickness Gauge is used to determine if the aggregate particles are to be considered as flaky, i.e. their thickness is less than 0.6 of their nominal size. The aggregate to be classified is separated into seven sieve fractions from 6.3 to 63 mm, and each fraction is examined separately. The Length Gauge (Elongation Index BS), is used to measure the elongation index of aggregates. When the length of the particle is more than 1.8 of the midsize of the sieve fraction, it is considered elongated. The aggregate to be classified is separated into six sieve fractions from 6.3 to 50 mm and each fraction is examined separately
