(Audio) An Introduction to Asphalt Concrete Pavement Recycling (1 PDH Credit)

Instructor: PDH Direct

Credits: 0

Format: Online

This time-based course contains guidance for preparing plans and specifications and for ensuring the quality of recycled bituminous concrete. In addition, this publication provides useful information to production, and laydown of recycled pavement mixtures. The emphasis is on airfield pavements, however, the concepts also apply to other pavements. Recycling pavement materials has proved to be a feasible process to rehabilitate worn-out pavements. Since recycled pavements will not always be cost-effective, recycling should be considered as an option when repairing or rehabilitating existing pavements. Upon successful completion of this course, participants will be able to: -Learn about the technology and equipment employed in pavement recycling -Learn about surface recycling -Learn about cold-mix recycling -Learn about hot-mix recycling -Learn advantages and disadvantages of asphalt concrete and Portland cement concrete pavement recycling -Learn about the application of rejuvenators -Learn about heater planning scarifying

(Audio) An Introduction to Cathodic Protection Concepts (1 PDH Credit)

Instructor: PDH Direct

Credits: 0

Format: Online

This course provides the basic concepts of cathodic protection, together with important criteria and precautions to be observed. Corrosion of metals is a result of electrochemical reactions. An electrochemical reaction is a chemical reaction accompanied by a flow of electrical current. The driving force for the corrosion of metals through electrochemical reactions is the free energy of the metal atoms in their metallic form. All chemical systems tend to change so that the free energy present is at a minimum. This is analogous to the flow of water downhill to minimize the free energy due to gravity. Most engineering metals are found in nature in a form with low free energy. These metal ores are chemical compounds consisting of the metal atoms combined with other atoms such as oxygen or sulfur. The process of breaking up these ores into their metallic and non-metallic atoms involves an addition of energy in order to free the metal atoms from the natural, low energy content chemical compounds. The corrosion process is driven by the tendency of these metal atoms to revert to their natural state. If corrosion products are analyzed, their chemical composition is usually identical to the ore from which the metal was originally obtained.

(Audio) An Introduction to Cathodic Protection Inspection and Testing (2 PDH Credits)

Instructor: PDH Direct

Credits: 0

Format: Online

This time-based course includes criteria and inspection actions that, when used either separately or in combination, will indicate whether adequate cathodic protection of a metallic piping system has been achieved. The effectiveness of cathodic protection or other corrosion control measures can be affirmed by visual observation, measurements of pipe wall thickness, or by use of internal inspection devices. Because such methods sometimes are not practical, meeting any criterion or combination of criteria in this chapter is evidence that adequate cathodic protection has been achieved. When excavations are made for any purpose, the pipe should be inspected for evidence of corrosion and/or coating condition. Apply sound engineering practices to determine the methods and frequency of testing required to satisfy these criteria. The criteria in this discussion have been developed through laboratory experiments and/or verified by evaluating data obtained from successfully operated cathodic protection systems. Situations may exist where a single criterion for evaluating the effectiveness of cathodic protection may not be satisfactory for all conditions. Often a combination of criteria is needed for a single structure.
