TECHNICIAN QUALIFICATION PROGRAMThe Arkansas State Highway and Transportation Department (Department) has contracted with theUniversity of Arkansas to conduct training for qualification of technicians at the Center for TrainingTransportation Professionals (CTTP).Qualification of technicians is in four areas of materials testing: 1) Basic Aggregates; 2) Soils/Aggregate;3) Hot Mix Asphalt; and 4) Portland Cement Concrete Testing. Before a technician may become qualifiedin Soils/Aggregate, Hot Mix Asphalt, and Portland Cement Concrete, the technician must first becomequalified in Basic Aggregates. The Center address is:Center for Training Transportation ProfessionalsUniversity of Arkansas at Fayetteville4190 Bell Engineering CenterFayetteville, Arkansas 72701(479) 575-3997Fax (479) 575-7639Qualification includes a demonstration of proficiency by the technician and a written test covering thearea of qualification. Upon acceptable completion of this program, the technician will be issued astatement of qualification showing the technician’s area of qualification. Technicians must recertify everyfour years for Soils and Hot mix asphalt. Concrete recertification is required every five years.The areas of qualification and the items included in each area are as follows:1) Basic AggregatesSampling by Random NumberSampling of AggregatesReducing Field Samples SizeMoisture ContentDeleterious MaterialsCrushed ParticlesParticle Size Determination (Gradation)Materials Finer Than #200 by WashingFine Aggregate Specific GravityCoarse Aggregate Specific Gravity2) Soils/AggregateSampling SoilsDry Soil PreparationWet Soil PreparationMoisture Content of SoilsMoisture Using Calcium Carbide TesterParticle Size Determination (Gradation)Atterburg LimitsProctors & Coarse Particle CorrectionIn-place Density & Moisture DeterminationNuclear MethodsAHTD 465AASHTO TAASHTO TAASHTO TAHTD 302AHTD 304AASHTO TAASHTO TAASHTO TAASHTO T2, AHTD 35248, AHTD 349255, AHTD 34827, AHTD 305118485AHTD 30AASHTO T 87, AHTD 35AASHTO T 146AASHTO T 265, AHTD 348AASHTO T 217, AHTD 347AASHTO T 88, AHTD 352AASHTO T 89 & T 90AHTD 353 & 354AASHTO T 99, T 224,T 180, & T 272AHTD 350, 356, 344, & 355AASHTO T 310, AHTD 330

IN-HOUSE PROCEDURE #PROCEDURE FOR VERIFYING SIEVESItem: SievesPurpose:This method provides instructions for checking the physical condition of laboratory test sievesranging in size from 75 mm (3 in.) to 0.075 mm (No. 200).Inspection Equipment Required:1. A caliper readable to 0.01 mm (Use for No. 4 sieve and coarser.)Tolerance:Sieves shall meet the physical requirements specified in AASHTO M 92.Procedure:(Step 1 applies only to sieves having openings greater than or equal to 4.75 mm)1. Select approximately 30 openings (or all square openings if less than 30), in segmentsof 3 or 4 openings along a 45-degree line. Measure and record both dimensions of eachsieve opening.2. Inspect the general condition of the sieve. Check the frame and solder joints for cracksor holes (check for pin holes in the finer sieves).3. Make sure the sieve has an appropriate label.4. Check for tightness of the wires on each individual sieve.

IN-HOUSE PROCEDURE #PROCEDURE FOR CALIBRATION OFSCALES OR BALANCES(AASHTO M 231)Purpose:This procedure provides instructions for checking the accuracy of scales and balances.Inspection Equipment1. Standard Weight Set of sufficient mass to reach 90% of scales capacity.2. A level is required to check the scale's level position, if one is not built into the unit.Procedure:1. Turn electronic scales on allowing for a warm up of approximately 30 minutes.2. Ensure that the scale base is seated on all comers and is level. (NOTE: Some leveling devicesare located under the scale pan.3. Be aware of excessive air movement during the calibration process. Document if airmovement appears to be excessive.4. Check for Off-Center Error. Measure this effect by placing the load (90 % of capacity) atvarious positions on the pan and observe any differences in indication. The difference betweenthe lowest and the highest indication is the maximum Off-Center Error, which should be withinthe accuracy range listed for the class of scale being checked.5. Set the zero point and the full-scale indication. Place weights on the pan in increasingincrements as indicated on calibration form. Observe and record the indications. The differenceat any point is the inaccuracy.
