An Interactive Webbook on Bases, Subbases, Pavement, and Misc. Construction

We have all driven on roadways. This surface is usually asphalt or concrete. Did you know that there are layers of materials under the roadway driving surface that are engineered to carry the load of vehicles traveling on them? Those underlying layers include the base and the subbase. Pavements are typically classified as either flexible or rigid.  Asphalt concrete is considered a flexible pavement and Portland cement concrete is considered a rigid pavement. They are named in this manner for the reason you are likely thinking – one of these pavements flexes under load, and the other really does not.

This webbook unit covers the general aspects of base and subbase construction, general aspects of pavement construction, and the general aspects of miscellaneous construction. In addition the webbook provides comprehensive discussion of 21 typical items of work related to those three scopes of work, focusing on the ‘what and how.’ This in-depth knowledge will give the reader a solid foundation for real-world applications in the field.

To effectively and safely construct an item of work related to those scopes of work, one must learn to characterize base and subbase construction, pavement construction, and miscellaneous construction.

One must know how to identify the scope of work for related items of work, learn how to identify the applicable work tasks, and know how to conduct work planning and cost estimating analyses. One must also know how to integrate and sequence the work tasks to develop the project schedule, understand the related testing and sampling, and field inspections for overseeing the specific items of work, and the related performance analyses during construction.

Technology is transforming the learning environment, but one thing that remains the same is that learners want engaging, real-world content. To that end, we have gamified learning in this webbook unit by incorporating several interactive and engaging elements throughout. We hope this will help focus and engage the learner. We are aware that people’s attention spans have become shorter in recent years, and it is essential to provide meaningful real-world tools for work and for learning to meet the needs of today’s learners, which is exactly what we have done in this webbook unit.
