Which option is a factor that contributes to poor pavement quality?

• A. Adequate Compaction
• B. Lack of Training
• C. High-Quality Materials
• D. Proper Drainage

Answer: (B)

The main factor this question tests is how important trained personnel are to achieving good pavement quality. Even with good materials, proper drainage, and the right compaction equipment, quality hinges on people correctly executing the paving process. Training covers essential practices such as selecting and handling materials, maintaining the correct asphalt temperature, applying and measuring compaction properly, conducting density and quality control tests, recognizing moisture issues, and ensuring joints and drainage are correctly constructed. When workers lack this training, they’re more prone to mistakes like improper mix temperature, incorrect compaction timing or effort, inadequate density, and poor QC, all of which can lead to defects and reduced pavement life. So, the absence of training directly undermines pavement quality, making it the factor that contributes to poorer results.
