The continuous eight-wheel flatness meter is applicable to the important data indexes of highway, urban road, airport runway and other pavement construction inspection, completion acceptance, and road maintenance. It has the functions of collecting, recording, analyzing and printing, etc. 6.5-inch LCD, wireless data collector, main controller in the car, using on-board power supply. It can calculate and print flatness value, average value, out-of-tolerance times, out-of-tolerance accumulation, area and other data.

Cleveland Open Cup is designed and made as per standards GB/T3536-2008 Petroleum Products - Determination of Flash and Fire Points - Cleveland open cup method and ASTM D 92 Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester. It is applicable to all petroleum products with flash points above 79℃ and below 400℃ except fuel oils.

The Los Angeles Abrasion Machine is used for determination of the aggregates resistance to fragmentation. The machine consists of an electronic control unit and a rolled steel drum having an inside diameter of 711 mm and internal length of 508 mm. The drum is rotated at a speed of 30-33 r.p.m. The machine is equipped with an automatic counter, when the preset revolution count is reached, the machine will stop automatically. The drum is equipped with an interlock device which allows the operator to lock the drum into position for easy loading/unloading of the sample.

The double-end face grinder machine is the main equipment necessary for the production of standard samples for mechanical testing of various rock, mineral, concrete and other non-metallic solids. This machine works with the coring machine and rock cutting machine produced by our factory to process the high-precision cube or cylinder test samples you need. It is suitable for departments such as colleges and universities, water conservancy and hydropower, geology and minerals, transportation, and construction. The machine is composed of a base table, a grinding power head, a variable speed transmission system, and an electric control device. The whole machine is easy to operate, and the automatic feed performance is stable.

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).

This series of testing machine takes hydraulic pressure as power, USES electro-hydraulic servo control technology to test the compressive mechanical properties of cement, mortar, brick, concrete and other building materials, and shows the loading force value, loading speed and loading curve. Test data is processed, stored and printed automatically.
