Excerpt from Elements of Highway Engineering III, containing, in detail, methods for determining physical and chemical properties of bituminous and non-bituminous highway materials, will be found of value to professors who wish to elaborate upon the subject of essential properties of materials and their determination. For a course constituting one hour a week for a half year, it is suggested that the subject matter might be reduced in amount by the omission of the text covering examples of state legislation, pages 31 to 36; surveying and mapping, pages 64 to 7 5; mining and manufacture of bituminous materials, pages 196 to 210; interpretation of tests of bituminous materials, pages 214 to 222; descriptions of machines, pages 98 to 111, 241 to 247, and 288 to 293; sidewalks, curbs, and gutters, pages 406 to 420; and highway structures, pages 421 to 450. The total number of pages thus eliminated amounts to about 110. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
