Excerpt from Dust Preventives and Road Binders The object of this book is primarily to furnish road engineers with a working knowledge of the characteristic properties of dust preventives and road binders now in use, and to develop certain fundamental principles relative to their selection and application. During the past few years there has been a rapidly growing demand for such information, which has so far been met in a not altogether satisfactory manner. The subject of dust prevention and road preservation is at present in a transitional state, and there is unquestionably much yet to be learned regarding the effect of certain properties of road binders upon the results obtained in practice. It is hoped, however, that this work may serve as a basis for further development and that it will prove of some assistance to those who are interested in the use of such materials. The conclusions as presented are based upon experience which the author has acquired both in the laboratory and in the field in the past five years of his service with the United States Office of Public Roads. During his connection with this office he has had under his personal supervision the examination of practically all varieties of road binders and their use under varying conditions in many parts of the United States. Throughout this book the mention of trade names as applied to the results of examination of road binders has for the most part been purposely avoided for the reason that different lots of these products have not as a rule shown definite and uniform characteristics. The ideas of producers, with reference to the manufacture of their materials, are undergoing a process of evolution, and in spite of the present lack of uniformity it must be admitted that a general tendency is being exhibited toward the improvement of these materials.
