SECTION 401
(n) Procedure for fine grading the top of the surface to be paved.
3.17.1.3 The Plan shall include the following personnel performing the described functions and meeting the following
minimum requirements and qualifications:
A. Plan Administrator shail hold certification as NETTCP OA Technologist and meet one of the following qualifications:
(a) Professional Engineer with one year of highway experience acceptable to the Department.
(b) Engineer-In-Training with two years of highway experience acceptable to the Department.
(c) An individual with three years highway experience acceptable to the Department and with a Bachelor of Science
Degree in Civil Engineering Technology or Construction.
(d) An individual with five years of paving experience acceptable to the Department.
B. Process Control Technician(s) (PCT) shail utilize test results and other quality control practices to assure the quality
of aggregates and other mix components and control proportioning to meet the job mix formula(s). The PCT shall
periodically inspect all equipment used in mixing to assure it is operating properly and that mixing conforms to the mix
design(s) and other Contract requirements. The Plan shall detail how these duties and responsibilities are to be
accomplished and documented and whether more than one PCT is required. The Plan shall include the criteria utilized
by the PCT to correct or reject unsatisfactory materials. The PCT shall be certified as a Plant Technician by the New
England States Technician Certification Program or be a Materials Testing Technician in Training, working under the
direct observation of a NETTCP certified Plant Technician.
C. Quality Control Technician(s) (QCT) shall perform and utilize quality control tests at the job site to assure that
delivered materials meet the requirements of the job mix formula(s). The QCT shall inspect all equipment utilized in
transporting, laydown, and compacting to assure it is operating properly and that all laydown and compaction conform
to the Contract requirements. The plan shall detail how these duties and responsibilities are to be accomplished and
documented, and whether more than one QCT is required. The Plan shall include the criteria utilized by the QCT to
correct or reject unsatisfactory materials. The QCT shall be certified as a HMA Paving Technician as certified by the
North East Transportation Training and Certification Program or be a Materials Testing Technician in Training, working
under the direct observation of a NETTCP certified HMA Paving Technician.
3.17.1.4 The Plan shall detail the coordination of the activities of the Plan Administrator, the PCT and the QCT. The Plan
shail also detail who has the responsibility to reject material, halt production or stop placement.
3.17.1.4.1 All issues agreed to at the Pre-Paving meeting shall be considered to be part of the Plan.
3.17.1.5 Asphalt pavement shall be sampled, tested, evaluated and recorded by the Contractor in accordance with the
minimum process control guidelines in Table 401-3.
3.17.1.5.1 Cross slope shall be measured on every pavement lift using the method described in 3.17.3.5.1 prior to
placement of subsequent lifts. Particular emphasis on the first pavement lift shall be required when correcting existing
substandard cross slopes. Cross slope measurements exceeding 0.5% from the specified cross slope for that location shall require
an adjustment in ongoing or subsequent paving operations to correct the deficiency. Iftwo or more consecutive measured sublots
are greater than 0.5% from the specified cross slope, paving operations shall cease until the Contractor submits a corrective action
satisfactory to the Engineer.
