DEVELOPMENT IN ASPHALT ENGINEERING
This paper contains discussion of seven aspects of asphalt engineering--asphalt production, recycling of reclaimed pavements, cleaning of road surfaces, spraying of bituminous binders, laying of bituminous pavings, compaction of bituminous surfacings, and staff training for road working sites. There is an extensive discussion of asphalt production. The two methods of production--batch mixing and continuous mixing--are described, and there is a comparison of the advantages and disadvantages of the corresponding mix plants. Also, there is a discussion of the benefits derived from the latest technological improvements such as: stricter control conditions, relatively lower production costs, sites with more hygenic and comfortable working conditions, and easier erection and transportation of plant facilities. The other subject areas, with the exception of compaction of bituminous surfacings, contain only brief discussions. The different types of compacting equipment are described. The most advanced machines used for base courses are vibratory rollers and rubber tire rollers; and for surface courses, they are static rollers and rubber tire rollers.
