Instron 4465 Testing System is used for racing surface material triaxial shear strength test (ASTM D4767). A latex tube is used to build a test sample in an aluminum mold first, and then the test sample is placed in a cell filled with water. By varying the confining pressure and temperature of the water, track loading by the hoof during the propulsion phase of the gait is replicated. The axial load is applied and the displacement is measured by the equipment. The digitized data is then transferred to a computer connected to the testing system. The data is processed for four different confining pressures and the shear strength, friction angle and cohesion of the testing sample are calculated. These mechanical properties will be used to evaluate the behavior of the material at a range of moisture content and temperatures..
Thermo Scientific Digital Controlled Water Bath is used to control the confine temperature of the triaxial test cell during the triaxial shear strength tests. The water temperature ranging from 0.40C to 500C in the cell is insured by the water bath. The digital controller attached to the water bath allows the water temperature to be controlled in the accuracy of one decimal place.
Lab Line Digital Controlled Vacuum Oven is the key equipment for the moisture removing before any test and for solvent evaporating during the wax separation test of the synthetic racing track material. The sample is dried fast and complete by the vacuum environment inside the oven; the possible error of the test result is then eliminated.
Temperature Control Lab Oven is used to dry dirt racing track material in order to test the moisture content and prepare the dirt sample for the further testing (ASTM D2216). The external thermal couple is used to control the temperature accurately. The capacity of simultaneously running multiple testing projects is granted by the employment of multiple ovens.
Jelenko Muffle Furnace is used to remove the organic content completely in the dirt racing track surface material by heating the sample up to 4400C. By comparing the weight of the sample before and after the heating into the furnace, the organic content is calculated (ASTM D2974). The samples with the organic content burned off can then be used to perform other tests.
Flow Sciences Chemical Hood is used for wax separation of the synthetic racing track surface material. The toxic and flammable chemical solvent is handled safely inside the hood by the forced air ventilation. Two ultrasonic cleaner are used to vibrate the synthetic material in the beakers filled with chemical solvent to insure the complete dissolving of the wax into the chemical solvent.
Hydrometer is used to determine the percentage of particles of different size in the dirt (ASTM D422). During the test, the density of the dirt and water suspension is measured at several time points; the percentage is then calculated based on the measurements.
TDS Testr11 Probe is 
used to determine the salt content of the racing track surface dirt materials. By measuring the Total Dissolved Solid (TDS) and the temperature of the suspension, the salt content is calculated by a computer program.
Panasonic Digital Microscope is used to observe the Micro structure of the fiber and detailed the shapes of the sand in the racing track surface material. The digital signal is obtained by the computer connected and the images can then be stored in the computer or printed by a printer.
strong>Sieve Separation System is used to separate the dirt material and the de-waxed synthetic material to determine the percentage of the particles and fibers with different size. During the test, several standard sieve screens with different sieve numbers are used; the percentage of different particle or fiber size is obtained by measuring the weight of each sieve screen contains.
Falling Head Permeability Testing Setup is used to test the permeability of the racing track surface material (ASTM D5856). A test bar is built first in permeameter connected to the lower end of the burette. The speed of the water running through the test bar is measured. The permeability of the sample is then calculated based on the measurement, the environment temperature and the forming moisture of the testing bar.
Sartorius GE812 Digital Scale is used to weigh the racing track surface sample with the capacity of 810 grams. Two decimal places accuracy is essential for the tests based on the change of the weight during the test.
Ohaus Scout-Pro 4000g Scale is used to measure the weight of the racing track surface sample up to 4.0 kilograms when a large amount of the material is needed in the tests.
Centrifuge will be used to determine the composition of the synthetic racing track surface material.
