AGGREGATE

Trainee: (2-4 months), 1 season, evaluated by PDOT and evaluated as a tester until formal class in fall. DME/DMM must sign application.

Technician: Applicant must successfully pass a written test (Penn Dot Central Lab in Harrisburg) and 1 season of documented testing, certification number will be assigned. DME/DMM must sign approval. Every 5 years, must be reevaluated by District materials unit.

Technician (training/education/job requirements)

AGGREGATE:
The trainee MUST be able to do basic math, some statistical analysis (PWL) along with basic computer skills. During the training period (typically 3-6 months), “testers” must learn the many test methods that apply to aggregate testing and how they fit into everyday work. There is also the SAFETY in and around the quarry. Every day there are many gradation tests done in order to develop a smooth operating routine of testing aggregate.

Good communication skills are an essential element of this job, as interaction with PDOT, PTC, and various consultant inspectors as well as quarry foreman/superintendent, dispatcher, and pay loader operator are all routine.

The basic test procedures are:
Sampling, reducing samples, moisture and gradation tests of anti-skid materials, sieve analysis, wash tests, order and releases from field inspector, truck weight and monitoring, fineness modulus, and long graded aggregates (2A and 2RC). These tests CANNOT be run with sloppy workmanship. Accuracy is crucial. Samples can weigh up to 50+ pounds depending on type of material.

As the “tester” improves upon their proficiency, there are then various Quality tests that need to be done for annual requalification of the quarry to be an approved PDOT source.

The more critical quality tests include:
Specific gravity of aggregates, absorption of aggregates, uncompacted void content, sand equivalency/clay content, wet-dry durability, flat and elongated aggregate particles, Los Angeles abrasion tests, and sodium/magnesium sulfate testing. These tests must have a great deal of attention paid to, as they are reliant upon accuracy.

The last discipline of an aggregate technician is the record keeping. It is MANDATORY for PDOT and PTC as well as New Enterprise. The record keeping is very critical, as our certification of compliance is done through this. The PDOT/PTC plant production book is a compilation of EXCEL worksheets and folders in a format per PDOT specification. It is kept for a period not less than seven years. (The certification of compliance and the record keeping CANNOT have a “tester” signature, only a certified Aggregate Technician) Most training on record keeping can be accomplished within 2 months.

After the trainee has worked through this learning period and has been evaluated by PDOT district materials inspection staff to have comprehensive knowledge, the area QC manager can apply for an admission into the 2 day class (TEST) at (Penn Dot Central Lab – Harrisburg) upon a passing score; the tester becomes a technician and is assigned a certification number.

Already approved technicians from surrounding states (Mid-Atlantic region) can skip the training period and can take the test for certification after a short 1 day update/refresher course.

The certification is for 5 years and MUST be renewed through the District Material Engineer with a written test in order to stay current.

BITUMINOUS

Trainee: (4-7 months), 1 season, evaluated by PDOT and evaluated as a “technician in training” until a formal class is available. DME/DMM must sign application.

Level 1

Technician: Applicant must successfully pass a written test and 1 season of documented testing, certification number will be assigned. DME/DMM must sign application.

Level 2

Technician: Applicant must be a certified Level 1 technician and attended an approved hands-on SuperPave volumetric design course with 3 seasons of documented testing. DME/DMM must sign application. Every 5 years, must be reevaluated through documented work history.

Technician (training/education/job requirements)

BITUMINOUS: (LEVEL 1 & 2)

The trainee should already be aggregate certified, or at the least, very experienced. A trainee MUST be able to do intermediate math, statistical analysis along with intermediate computer skills. During the training period (typically 5-8 months), “technician in training” must learn the many test methods that apply to bituminous testing and how they fit into everyday work. The environment around the bituminous plant is possibly more dangerous than a quarry. The equipment (pay loaders, tri-axles, and Euclid’s) are moving at a faster pace. Safety in the laboratory is another concern as ignition oven temperatures exceed 1000 F. Also Bituminous Technicians MUST be able to work very unusual hours, as mixing to fill silos can start as early as 1:00 AM and sometimes Sundays and holidays.

Excellent communication skills are an essential element of this job, as interaction with PDOT, PTC and various consultant inspectors as well as the plant operator, pay loader operator, job foreman, and the area QC manager are all routine

The basic testing includes:
Aggregate gradations, RAP gradations, moistures, order and release from field inspector, truck weight/monitoring , scale checks, setting up PTM #1 (random numbers prior to testing each type of material) and setting up blends of aggregate, all before mixing the material. These tests CANNOT be performed with sloppy workmanship. Accuracy is very critical. As the “technician in training” improves their proficiency, there are many more decisions to make within a very short time frame.

The more critical decisions include:
Blend changes, and hot bin sampling and bin pull changes.

The most critical testing includes:
Sampling, quartering (reducing sample size), asphalt content and washed gradation, volumetric samples, and maximum theoretical specific gravity are the tests that are the most crucial and require special attention to detail. The details are: correct asphalt correction factor in ignition oven, correct wash #200 sieve correction factor, correct weight of sample, correct sample weight for volumetric samples, correct sample weight for maximum theoretical specific gravity, and regular maintenance on the ignition oven as well as the gyratory compactor. The “technician in training” MUST know what all of the values they achieve through the testing and what they represent as well as the specifications for each particular mix design.

The last discipline of a bituminous plant technician is the record keeping. It is MANDATORY for PDOT, PTC as well as New Enterprise. The record keeping is very critical, as our certification of compliance is done through this. The PDOT/PTC production book is a compilation of EXCEL worksheets and folders in a format per PDOT specification along with a web-based program for Penn Dot. Records are kept for a period of not less than seven years. (The certification of compliance and the record keeping CANNOT have a “technician in training” signature, only a certified bituminous technician). Most training on record keeping can be accomplished within 3 months, as the amount of record keeping is nearly twice that of aggregate and concrete. The record keeping/paperwork annual mix design submittal process takes typically 2-4 weeks.

Typically after one construction season, a “technician in training” who has worked in the presence of a PDOT materials inspector, can apply to become a Level 1 Bituminous Plant Technician. The area QC manager enrolls the prospective plant technician in a 3 day class (TEST) at Penn State University transportation center (NECEPT). Upon successful completion of the written test, the bituminous technician will be assigned a certification number.

The certification is good for 5 years and MUST be renewed with either a complete course or have enough work experience (500 hours/year) during the construction seasons along with updates (PAPA technical meetings). When a certified Level 1 technician has their first 3 years of service, the area QC manager can send the certified technician to a Volumetric SuperPave design course (5 day course at the NECEPT center), upon successful completion of the written test, the plant technician can apply for Level 2 status. The Level 2 Bituminous technician is the ONLY person who can submit, and design bituminous mixes. Every 5 years, the Level 2 Bituminous technician MUST submit their 5 year work history which includes; tonnage, hours worked, and the particular SR/Sec. of each job to the District Materials Engineer to sign off for a renewed certification.

CONCRETE

Plant

Trainee: (3-6 months), 1 season, evaluated by PDOT.

Plant

Technician: Applicant must successfully pass a written test. PDOT uses SS# for certification number. DME/DMM must sign approval.

Field

Trainee: (1-2 months), 1 season, evaluated for season only until ACI and PDOT class.

Field

Technician: Applicant must first take and pass ACI written and performance test. Upon passing, PDOT module is a written test only, certification number will be assigned. DME/DMM must sign approval. Every 5 years, must be reevaluated by taking both classes again.

Technician (training/education/job requirements)

CONCRETE: (PLANT/FIELD)

The trainee should already have aggregate testing experience or already be aggregate certified. A trainee MUST be able to do basic math, some statistical analysis along with basic computer skills. During the training period (typically 4-7 months), “technician in training” must learn the many test methods that apply to concrete testing as well as data sheets from cement, pozzolan and admixture suppliers (PLANT) and how they fit into everyday work. The knowledge to design a concrete mix for the proper application and also ACI/PDOT specifications is a more advanced discipline of this certification that generally takes several years to develop. The safety around a concrete plant or in the field is as important as a quarry. The equipment (mixers and pay loaders) is moving at a faster speed. Concrete testing can be as little as 15 loads per day (PLANT) to as many as 60 loads (FIELD).

Excellent communication skills are an essential element of this job, as interaction with PDOT, PTC and various consultant inspectors as well as the panel operator, dispatcher, area QC manager and pay loader operator are all routine.

The basic testing (PLANT) includes:
Aggregate gradations, moistures, aggregate temperatures, order and release from field inspector, scale checks, preparing of the batcher mixer slip, sampling of fresh concrete from the mixer truck, concrete temperature, plastic air test, slump test and casting test cylinders/beams. These tests CANNOT be performed with sloppy workmanship, accuracy is very critical. The sampling, temperature, air test, slump test and casting test cylinders/beams are the primary AND critical points of the (FIELD) technician. As the “technician in training” improves their proficiency, there are much more responsible decisions to make in a very short time frame.

The most critical (PLANT) decisions include:
Increasing or decreasing the air-entraining admixture, increasing or decreasing the water reducer/retarder, anticipated slump loss to jobs, using the plant water chiller/water heater to control the temperature, and moisture control of the aggregates. Those quick decisions are needed to control the concrete mixture, their consequence determines if the load is accepted or rejected.

All concrete technicians MUST have the specific knowledge of strength requirements of the mix they ship, this in turn leads to testing of concrete cylinders or flexural beams.

The last discipline of a concrete technician is the record keeping. It is MANDATORY for PDOT, PTC as well as New Enterprise. The record keeping is very critical, as our certification of compliance is done through this. The PDOT/PTC production book is a compilation of EXCEL worksheets and folders in a format per PDOT specification. It is kept for a period not less than seven years. (The certification of compliance and the record keeping CANNOT have a “technician in training” signature, only a certified Concrete technician). Most training on record keeping can be accomplished within 2 months.

After a “technician in training” has worked in the presence of a PDOT materials inspector for typically 3 + months, they’ll be EVALUATED as a Concrete Plant Technician by a staff member of the PDOT district materials unit. The evaluation includes proficiency in the physical testing as well as a 100 question test. Upon passing both tests, the “evaluated technician” becomes a certified PLANT TECHNICIAN.

The evaluation and certification for a (FIELD) technician is entirely different. The prospective technician must have 3 weeks experience in field testing. Then the area QC manager will enroll them in the ACI Grade 1 Field Testing class. Passing the written test and the physical tests is a NATIONAL certification. The area QC manager will then enroll them in the PDOT module which is another written test administered by PDOT Quality Assurance staff. Upon passing this written test, the FIELD technician is now certified and assigned a certification number.

Already approved technicians from surrounding states (Mid-Atlantic region) can skip the training and can take the test for certification after a short 1 day update/refresher course.

The ACI certification is good for 5 years and MUST be renewed with the complete course. The PDOT module is good for 5 years also and MUST be renewed through the District Materials Engineer with the complete course to stay current.
