Contained information relating to asphalts, uses, brief history, definitions, tests, and specifications. This reference is no longer published by the Asphalt Institute. This book is a great study aid for electrical exams and is specially designed to increase your speed by getting you familiar with those hard to find references in the NEC.
100% recommended, It worked for finding the really specific and obscure code references as well as helped me verify the ones that I felt confident about.Joanna Gonzalez
