NICET Construction Materials Testing (CMT) Soils Level II Certification Exam Bank: Newest Comprehensive Practice Questions, Step-by-Step Math Calculations, ASTM/AASHTO References, and Detailed Answer Explanations (2026 Edition) Overview Pass your NICET Level II Construction Materials Testing (CMT) Soils certification exam on your first attempt with this complete Question All-In-One Practice Exam Bank. Engineered specifically to align with the latest NICET Work Element and Content Outlines, this study guide provides rigorous preparation across all core technical domains, laboratory testing protocols, field inspection practices, and safety regulations. Key Features:  High-Yield Multiple-Choice Questions: Structured into 8 sequential parts (25 questions each) covering realistic exam scenarios.  Full Answer Explanations: Every question includes a detailed breakdown explaining why the correct answer is right and why distractors are incorrect.  Worked-Out Engineering Calculations: Complete step-by-step math derivations for phase relationships, dry density, relative compaction, sieve analysis ($C_u$ and $C_c$), Atterberg limits ($PI$, $LI$), and strain calculations.  Standard-Aligned: Grounded in active ASTM, AASHTO, and OSHA standards (e.g., ASTM D698, D1557, D6938, D2487, D4318, and OSHA 1926 Subpart P). Coverage This question bank delivers complete coverage across the following key domains: 1. Field Testing & Inspection (30% of Exam Bank)  Nuclear Density & Moisture Gauges (ASTM D6938): Direct transmission vs. backscatter modes, standard counts, trench corrections, depth limits, and radiological safety/US DOT transport rules.  Sand-Cone & Drive-Cylinder Testing (ASTM D1556 / D2937): Calibration of Ottawa sand, cone correction factors, and field density determinations.  Compaction Control & Subgrade Inspection: Proof-rolling procedures, lift thickness limits, moisture-density evaluation, and recognizing non-conforming fills. 2. Laboratory Testing & Material Characterization (35% of Exam Bank)  Moisture-Density Relationships (Proctor Tests): Standard Proctor (ASTM D698) vs. Modified Proctor (ASTM D1557), rammer drop heights/weights, blow counts, and oversized particle corrections (ASTM D4718).  Soil Classification & Index Properties (ASTM D2487 / AASHTO M145): Unified Soil Classification System (USCS) charts, A-line rules, dual symbols, and AASHTO group index calculations.  Atterberg Limits (ASTM D4318): Liquid Limit (Casagrande cup vs. fall cone), Plastic Limit, Plasticity Index ($PI$), and Liquidity Index ($LI$).  Particle Size Analysis (ASTM C136 / D6913 / D1140): Sieve analysis, wash loss over No. 200 sieve, hydrometer testing, and gradational parameters ($D_{10}, D_{30}, D_{60}, C_u, C_c$). 3. Soil Mechanics & Geotechnical Fundamentals (20% of Exam Bank)  Phase Relationships: Void ratio ($e$), porosity ($n$), degree of saturation ($S$), water content ($w$), wet density ($gamma_{text{wet}}$), and dry density ($gamma_d$).  Permeability & Consolidation: Constant-head vs. falling-head permeameters, preconsolidation pressure ($sigma'_p$), and rate of consolidation ($c_v$).  Shear Strength & Bearing Capacity: Unconfined compression ($q_u$), direct shear, triaxial testing (UU, CU, CD), and California Bearing Ratio (CBR) mechanics. 4. Safety, Standards & Site Operations (15% of Exam Bank)  Excavation & Trenching Safety (OSHA Subpart P): Soil classification (Type A, B, C), maximum allowable slope ratios, benching, and protective systems.  Sampling Protocols (ASTM D75 / D1587 / D1586): Disturbed vs. undisturbed sampling, Shelby tubes, Standard Penetration Test (SPT) N-value execution, and sample preservation.
