Frequently Asked Questions
How many questions are on the NICET CMT-Asphalt exam?
NICET publishes the exam as 110 questions in 170 minutes for Level I, 165 in 365 minutes for Level II (includes a 30-minute scheduled break), 138 in 335 minutes for Level III, and 88 items in 245 minutes for Level IV.
How much does the CMT-Asphalt exam cost in 2026?
Per NICET's standard-model CMT fee schedule, exam fees are $230 (Level I), $315 (Level II), $370 (Level III), and $425 (Level IV). Rescheduling more than 24 hours before the appointment within the testing window is generally free.
Who delivers the CMT-Asphalt exam?
NICET owns the certification and Pearson VUE delivers the computer-based exam at approved test centers. Register with NICET, receive an eligibility notice, and then schedule with Pearson VUE.
What work experience is required for each level?
Per NICET certification requirements, Level I requires 6 months of CMT experience (3 in asphalt), Level II 24 months (12 in asphalt), Level III 60 months (36 in asphalt) plus a personal recommendation, and Level IV 120 months (60 in asphalt) with a senior-level recommendation.
Which AASHTO standards should I focus on?
Prioritize AASHTO T 168 (sampling), T 27/T 30 (gradation), T 209 (Gmm), T 166 (Gmb), T 308 (ignition), T 312 (Superpave gyratory), T 245 (Marshall), T 283 (TSR), T 324 (Hamburg), and Superpave binder tests (T 240 RTFO, T 315 DSR, T 313 BBR).
How is in-place density verified for acceptance?
Nuclear gauges (backscatter for thin HMA surfaces, direct transmission for thicker lifts) are commonly used with core correlation to establish accurate Gmb-equivalent density. Non-nuclear gauges also require correlation. Most DOTs require 92-94 percent of Gmm, with joint density within ~2 percent of mat.
What is Superpave Ndesign?
Ndesign is the number of Superpave gyratory compactor gyrations at which the mix is designed for 4.0 percent air voids. It varies with 20-year design ESALs (traffic level) from ~50 to ~125 gyrations, with Ninitial and Nmax constraints to limit tender or overly stiff mixes.
How often do I recertify my NICET CMT-Asphalt credential?
Every three years through Continuing Professional Development. Technicians log CPD from technical training, industry participation, and supervised experience, then submit the record before the cycle ends.
