3 We want to build quality roadways but what is quality? Who is the customer? If you are an aggregate or binder supplier your customer is the asphalt producer. If you produce asphalt mix and sell it to a paving contractor your customer is the paving contractor. If you are an CEI inspector, your customer is the FDOT. But who is the ultimate customer? The taxpayers and the traveling public who pay for and use your pavements. 1-3

4 If you define it from the traveling public s point of view these would be the definition of quality. Smooth surface Quiet ride Minimization of traffic delays Adequate skid resistance Minimization of overall costs These are what customers expect out of each and every project. 1-4

5 If you define it from an asphalt contractor or a DOT point of view these might be the definitions of quality. But, are they? If the mix is not constructible, the chances of success are lower than one that is. Obviously the mix must conform or meet the specifications, and the finally, mix must satisfies functional requirements, e.g., carry the intended load it was designed for. A Traffic Level A mix is going to be different than a Traffic Level D mix. 1-5

6 Uniformity and consistency are important qualities for both asphalt mix production, as well as, paving. The percent within limits specification rewards uniformity and consistency as well as meeting the specification limits. 1-6

7 But, the big question is how to produce quality? Quality is produced when everyone on the project from the common laborer on the job to the company president or the FDOT Secretary pays attention to the details and does those things needed to ensure everything is done correctly in the best way that it can be. That is the purpose of this course and the other courses in the CTQP process to show you ways to do things right. 1-7

8 Quality for an asphalt pavement starts with the materials that will ultimately make up the mix. For the aggregates it starts at the quarry including the source of natural rock from which the aggregates are produced by drilling and blasting, excavating, crushing, and screening operations. If the material going into the asphalt is variable or of poor quality, so will the asphalt be when its made. All materials have inherent variability. It is up to the contractor and the materials suppliers to work together to make sure the final product is in good quality and falls within the specification limits. 1-8

9 Good materials management is necessary for the aggregates and the asphalt cement. You can see in the photo that although there are dividers separating the different stockpiles of materials, if the piles are not managed properly, one could spill into the other causing contamination. 1-9

10 If you enroll in Plant Level 2 you will learn details of plant calibration. The plants need to be calibrated and well maintained. All devices must be calibrated to known values to ensure accuracy and repeatability. The plants need to be calibrated and well maintained. Calibration today is much easier than it used to be as the plant computers do most of the work. 1-10

11 . The asphalt plant needs to be properly operated. Plants being sold today are highly automated and sophisticated, but the basic operation has not changed much. 1-11

12 Properly equipped labs with well calibrated and maintained equipment are crucial. A part of the CTQP program includes Plant Level 1 qualification and it stresses importance of running the tests correctly (no shortcuts) on properly calibrated equipment. People who work in the labs need to be well trained (CTQP qualified) to run the necessary tests. They need to have accredited and qualified laboratories that are properly equipped with calibrated and well maintained equipment. 1-12

13 Follow through and the attention to detail must continue throughout the paving operation. This course starts once the trucks are properly loaded and the temperature of the mix is taken. Remember that the job is not finished until the mix is delivered to the job site and placed in place at the proper thickness, texture, density and smoothness. If the mix properties vary during production, it could make achieving those objectives very difficult. And the attention to detail must continue through the paving operation. 1-13

14 You need to be aware and follow all safety requirements and wear all required personal protective equipment (PPE). Be highly cautious around both paving equipment and traffic moving through the work zone. Do not get caught between moving equipment. Class 2 safety vests are the minimum requirement for paving projects. No matter what - when you are around an asphalt plant or an asphalt paving operation the first priority is safety. It has been reported that one of the most dangerous jobs in the United States is road maintenance and construction. Many times you are working on roadways that have a significant volume of traffic. You need to look out for yourself and for your coworkers on the project. SAFETY IS NUMBER ONE!!!! 1-14

15 We will be looking at what the specifications call for in addition to what is considered best construction practices. These are the main topic areas we will be covering in this course. We will be looking at them from the same perspective as they are addressed in the specifications and what is considered best construction practices. 1-15

16 The difference between being qualified and experienced - 90 days is not enough time to make you an expert that will take a lifetime. For a first time Paving 2 qualification, the requirement is passing the Paving Level 1 proficiency AND written examinations. If Paving 2 qualification is kept current (not allowed to expire) Paving 1 would not have be taken again. Construction Training/Qualification Manual Asphalt Paving Level II Qualification Requirements The objective of this qualification is to assure that personnel responsible for inspecting asphalt pavement construction (paving and compaction) are familiar with Department specification requirements, good construction practices and equipment operation necessary to place and compact a Superpave mixture which will meet requirements for smoothness, texture, density, cross slope and thickness. All trainees seeking Asphalt Paving Level II qualification must: (1) Pass the Asphalt Paving Level II written examination. (2) First time qualifiers must possess an active Asphalt Paving Level I qualification at the time of taking the Asphalt Paving Level II written examination. (3) Have 90 days experience in asphalt paving operations or asphalt roadway testing. After a trainee has successfully met all of these qualification requirements, the trainee's qualification date will be added to the training database. Qualification shall be for five (5) years (60 months) from the date the last qualification examination requirement was satisfied. 1-16

17 The instructor(s) will be available before and after class to help answer additional questions, but once the exam starts they will be unable to help. Construction Training/Qualification Manual Asphalt Paving Level II Training Course This is a three (3) day course with a written examination on the last day (approximately 4 hours, multiple choice). This class emphasizes the need for uniformity and consistency of the mix, placement and compaction operations in achieving the specification requirements for texture, smoothness, density, cross slope and thickness. Equipment operation of pavers and rollers are presented. Balancing of delivery, milling, paving and compaction operations are demonstrated. Proper pavers operation for smoothness is emphasized. Proper roller operation is emphasized in order to achieve specific density. Department specifications for acceptance of mix on the roadway are reviewed. The basics of the statistical approach behind the specifications are presented in order to input data. The trainee will understand and be able to recognize problems and make suggestions for corrections in the paving operation. Random number table for sampling for density and thickness is explained. Identification and possible causes of pavement problems and the solutions are presented. The need for uniformity and consistency is explained. 1-17

18 An important note is the last bullet on this slide. This course is based on the January 2015 Standard Specifications for Road and Bridge Construction. You may be working on projects with specifications from a different date. It is very important to always check which set of specifications are on the job you are working on. Construction Training/Qualification Manual Training Course Written Examination An open book written examination (usually 4 hours, usually multiple choice) is administered at the end of the course. The examinations are electronically graded by the CTQP. The passing grade for this examination is 70%. Two weeks should be allowed for grading and posting of the examination results. 1-18

19 The CTQP Administrator was changed to a private vendor in 2005 and the qualification database is handled by them. Check the website above for more information about the CTQP program and how to look up your qualification and exam scores. The FDOT has approved a list of providers who teach various classes. There is a link to all courses and providers on this website. 1-19
