Abstract
SINCE the advent of the motor-car the use of bituminous materials in road-making has become more and more widespread, and a definite knowledge of the chemical and physical characters of these substances is of increasing importance to the road constructor. In the United States a number of the leading universities have instituted courses of instruction in highway engineering, which include laboratory practice in the testing of bituminous materials, and the manual under notice has been prepared by the author to meet the wants of students and instructors attending such courses. The first part of the book deals with the definition and classification of the various bituminous substances used by the highway engineer, and also with general matters such as the sampling and preparation of the bitumens for analysis. In the second and main division the author describes the methods of applying—the various tests—chemical, physical, and mechanical-by which the materials are assayed and evaluated. The de-scriotions are lucid and concise; they have evidently been drawn up by a writer who has first-hand knowledge of the special difficulties attending this class of analytical work. In the concluding part of the book the characteristics of the more important bituminous substances are discussed, including those of the fluid, semi-solid, and solid petroleum products, tars, asphalts, pitches, creosote oils, and bituminous aggregates. Typical analyses are given, and these are carefully I dissected in order to bring out clearly the proper I interpretation of the results. The book should 1 prove of value to municipal and other chemists who may have to deal with the substances in question, as well as to the students for whom it is especially written.
