This method has been designed to eliminate the inherent guess work built into ASTM C128 and AASHTO T84— the cur- rent cone and tamper methods in use today. This is easy to perform, easy to understand and easily reproducible between technicians and labs. The test is very easy to run and can be reliably run in the field. This can be especially helpful in asphalt operations where specific gravities can make a big impact on pay factors. This test lets the contractor check specific gravities on the material he is cur- rently using, not lab tests, which may not be cur- rent.

The system con- sists of a low pressure vessel fitted with a pressure gauge and an electronic scale and test accessories. Moisture measurements are made by mixing a weighed sample of the material with a calcium carbide reagent in the sealed pressure vessel. The reagent reacts chemically with water in the sam- ple, producing acetylene gas that in turn increases the pressure within the vessel. The pressure increase in the vessel is proportional to the amount of water in the sample, the moisture con- tent can be read directly from the calibrated pres- sure gauge. The tester is supplied complete with heavy-duty plastic carrying case, electronic bal- ance, beaker, cleaning cloth, cap, washer, scoop, steel pulverizing balls and cleaning brushes.

When used on aggregate of a known size, the void content provides the user with an indi- cation of the angularity, sphericity and surface texture as compared to other coarse aggregate of the same grading. In operation, the aggregate is allowed to free-fall 115mm from the funnel bot- tom into a 154mm diameter by 160mm high cylin- drical measure. The excess heaped aggregate is struck off using the included bar, the mass is measured, and the void content is computed. The apparatus consists of a stainless steel hopper, stand, measure and strike-off bar and a 170mm square glass plate for calibration of the measure.

Particle is elongated when its length (longest dimension) is more than 1.8 of the mid-size of the sieve fraction. Aggregate to be classified is separated into seven sieve fractions from 63 to 6.3mm, and each frac- tion is examined separately. Six labeled openings between pairs of metal pins measure particle from each of the six sieve cuts below 50mm. The mass of all elongated particles (failing to pass between pins) as percent of the sample is the elongation index.

Abrasion, Slake Los Angeles Abrasion Machine ASTM C131, C535; AASHTO T96 The LA abrasion machine is used to measure the degradation of mineral aggregate of standard gradings resulting from a combination of actions including abrasion or attrition, impact and grind- ing in a rotating steel drum containing a spec- ified number of steel spheres. The test is widely used as an indicator of the relative quality of var- ious sources of aggregate having similar mineral compositions. Humboldt’s design follows the ASTM-preferred design: • Features a welded, structural-steel frame, fab- ricated .5"-thick (913mm) abrasion-resistant steel drum, a removable shelf, bolted to the drum and a balanced drum assembly for easy rotation by hand. • The enclosed chain drive rotates the drum without a conventional slip clutch. This positive drive delivers greater testing accuracy. • The self-contained worm-drive, motorized speed reducer has anti-friction bearings and sealed lubrication. • The 1hp, electronically-controlled motor is equipped with large, push-button controls and an automatic overload cutoff. • The controls can be removed from the Abrasion Machine and mounted outside a sound enclo- sure or mounted on a nearby wall. Unit includes user-configured, revolution counter, a material catch pan and one abrasion charge consisting of 12 hardened-steel balls. Dimensions: 39" x 29" x 37" (991 x 737 x 940mm).

The apparatus consists of a base-mounted, motor- drive unit with two mesh drums and two water tanks with quick-release drive assemblies. The drums rotate at a speed of 20 revolutions per min- ute.

An aggregate sample is placed in a sealed stainless steel jar with an abrasive charge of up to 5,000g of 9.5mm diameter stainless steel balls and water, then rotated at 100rpm for two hours. Aggregate quality is determined by percentage loss in gra- dation results at completion. The micro-deval’s smaller size, smaller sample quantities and sim- pler procedure make this test method easier and less costly to perform than traditional methods. The micro-deval meets current ASTM, AASHTO, and Canadian test methods, as well as more strin- gent Texas DOT requirements. This contemporary version of the micro-deval test should not be con- fused with older versions originating in Europe which use different equipment and test protocol. A sophisticated electronic controller with optical sensing system accurately tracks test time, total revolutions and rpm of jars. Test duration may be controlled by either elapsed time or total revolu- tions. Jars stop within a fraction of one revolution at test termination. Jar revolution and speed data may also be used as a verification of machine performance. Sample jars revolve behind polycarbonate doors equipped with safety interlocks, so no moving parts are exposed during operation as opposed to older designs, which used unguarded open rollers. The micro-deval machine is a two-tier unit with sturdy steel frame. Each tier carries one stainless steel 5 liter sample jar, which has a 194mm ID and a 170mm internal height with locking cover. Power to the rubber-covered rollers is supplied by a 3/4hp, electric motor through a gear transmis- sion and chain drive. The unit is supplied with two jars and two 5,500g abrasive charges. A mag- net is included to assist in removing the abrasive charge after the test is complete. For additional sample preparation capacity and greatly reduced testing times, it is recommended that additional sample jars and abrasive charges be used. Overall dimensions are: 20.5" x 13.5" x 38" (521 x 343 x 965mm).

Can be used for correlation to unconfined or uniaxial compres- sive strength (UCS); testing on weak rocks, porous rocks and those with thin weathering crusts; cores; rectangular blocks and investigations of hardness near edges of samples. The impact energy of the Device D is approximately 1/200th that of the Type N rebound hammer. This makes it very suitable for testing on historical sites, very soft types of rock that cannot be tested with a rebound hammer and also on brittle rock cores that would be damaged by a rebound hammer. The impact Device S features the same impact energy, but with a much more durable ceramic impact body that is more suited to heavy users on harder rock. The Basic Unit includes: Equotip Touchscreen incl. Battery, Power Supply, USB Cable, Surface Roughness Comparator Plate, DVD with Software, Documentation, Carrying Strap and Carrying Case. Order Device D or Device S separately. Both devices come with the appropriate calibration blocks. Equotip 550 Basic UnitH-3417 Shipping wt. 4.9 lbs (2.2kg) RockSchmidt ASTM D5873 The RockSchmidt is a variation of the Silver- Schmidt rebound hammer, which has been adapted specifically for rock testing applications, such as UCS correlations or the prediction of pen- etration rates for tunnel boring machines and rotary drum cutters. The following features of the hammer make it ideal for rock testing applications: Impact Angle Independence: The rebound value is independent of the impact direction. Optimized for Field Work: Tighter sealing against dirt and dust intrusion for longer life. Significantly lighter and more ergonomic than the classic Schmidt hammer. A large number of readings can be saved and downloaded later to a PC. Preset Statistics: Statistics methods recom- mended by ISRM and ASTM are implemented into the hammer for automatic calculation of the rebound number. The option is also there to define a user specific statistics method. Unconfined Compressive Strength: ISRM rec- ommends a correlation between UCS and the rebound value based on the formula UCS = aebR (where R is the rebound value). A correlation in this format may be defined in the PC software and downloaded onto the RockSchmidt. Young’s (E-) Modulus: ISRM recommends a cor- relation between elastic modulus and the rebound value based on the formula Et = cedR (where R is the rebound value). A correlation in this format may be defined in the software and downloaded to the RockSchmidt. Weathering Grade: Impacting on the same loca- tion twice can be used to correlate to weathering grade. The ISRM recommended method has been included in the device. RockSchmidt, includes bat- tery charger with USB cable, DVD with PC soft- ware, carrying strap, grinding stone, documenta- tion and carrying bag.
