For determining the amount of carbon residue after evaporation, pyrolysis of oil, and to provide some indication of relative coke forming propensity.

Operated (AIM 563-1 ) The new design of centrifuge extractor is compact with in-built dimmerstat for speed variation from 0 rpm to 3600 rpm. Each unit is supplied complete with a set of 25 Filter Paper Discs.

High quality and versatile compression testing machine with certification of a UKAS accredited calibration.The CRT-CTM250-II was developed to perform a variety of compressive strength tests including Duriez, Indirect Tensile Strength and Marshall Stability. A rigid floor-standing test frame with bench-height working surface, twin columns and adjustable height cross-head houses a hydraulic cylinder with a load capacity of up to 300kN.

A high quality machine with which the user can easily and safely obtain accurate, repeatable results day after day.Gyratory compaction is considered to be one of the best methods of laboratory compaction for the assessment of compactibility and the manufacture of test specimens.Compaction is achieved by the application of a vertical stress (normally 600KPa) via end platens to a known mass of asphaltic mixture within a 100 or 150mm internal Ø mould.

The European Standards EN 13808 and EN 15322 demand this test according to EN 13588 as a basis for the CE marking of all polymer-modified binders for the intended use of surface treatment.Vialit Cohesion Pendulum by Cooper CRT-VCP is a testing device to analyse the cohesion of bitumen in road construction. The cohesion is one of the measures of the performance of a bituminous binder.

Easy-to-use, fast and accurate sawing systems. Best in class for safety features.Cooper Research Technology has developed easy-to-use sawing systems for fast, accurate cutting of beams for asphalt prisms (prepared in Cooper Research Technology’s Roller Compactors – small and large models) to be used for Four Point Bending Beam Testing in CRT-SA4PT-BB and CRT-LH4PT-BB, for Two Point Bending Beam testing in CRT-2PT, and cutting & dressing round cores and large & small wheel tracked slabs.

Designed to test three specimens simultaneously. The machine consists of a carriage moving over a lead screw. An electric motor driven reduction gear unit ensures smooth constant speed and continuous operation. The entire assembly is mounted with water bath completely encased in metal bound hardwood.

The most popular Roller Compactor worldwide is robust, reliable and the industry standard.The Roller Compactor is considered to be the method of laboratory specimen compaction that results in slabs of asphaltic paving materials with properties that most closely simulate those of materials in the highway.

Film stripping device is used to measure the resistance of bituminous mixtures to stripping of asphalt from aggregate particles. It is generally used to evaluate mineral aggregates & to judge the adhesion of the bituminous materials. The device consists of a disk on which 4 bottles are mounted. The disc rotates at a speed of approx. 100 rpm.

For determining the flash and fire points of petroleum products, except for fuel oil and those products which have open cup flash point below 79° C (175° F).
