This is a manual written for those who direct or physically construct asphalt seal coats. The text is based on field experiences. The manual contains: the reasons for seal coating; each type of seal coat discussed as to the purposes of the seal and how it is constructed; and particular emphasis on chip seals and the factors which can affect obtaining consistently good seal coats. Some of these factors are the weather, the road surface on which the seal is laid, the type of asphalt used, the handling and storage of the asphalt, the choice of cover rock, how to control the uniform distribution and application of the asphalt and rock, the coordination of the seal coat operation, and the post-seal inspection and possible immediate correction. This manual is concise but detailed in the appropriate areas with liberal use of graphics.
