The Asphalt Binder Handbook is a comprehensive manual that is devoted entirely to information about asphalt binders or bitumen. It is a compilation of the information in numerous other AI publications including the SP-1, MS-4, MS-5, MS-19, and MS-25 manuals, melded with previously unpublished information on topics such as the Multiple-Stress Creep Recovery (MSCR) test, testing variability and resolution, and the generation of mastercurves. Fully illustrated.
My wife has been married to an engineer for over 15 years. In that time, she has become somewhat accustomed to my engineering habits. One of the habits that she will never quite understand is my casual reading of technical manuals.
Chapters five, six and seven cover emulsions and cutbacks, air-blown asphalts and modified asphalts. Product histories, uses, production and testing methods are outlined in the same appropriate but not overly technical detail. The book also includes a section on the safe handling of liquid asphalt.
MS-26 can be read from cover to cover or used as a quick reference guide. For those of us that are familiar with the liquid asphalt industry, but not in the liquid lab every day, it is an excellent and concise point of reference for all things binder related. Because of the way it is written and organized, it is also a great source to help those with a limited understanding of our industry gain critical knowledge.
This course is a hands-on training program intended to introduce the student to the testing of roofing asphalt binders. Learn the test procedures, calculations and criteria involved with grading roofing asphalt binders. Develop and hone your skills during intensive hands-on labs including sample preparation and testing including softening point (Ring & Ball, Mettler Cup and Ball), penetration, flash point (Cleveland Open Cup), ductility, and rotational viscosity. Observe demonstrations of the solubility and stain index tests. Review rheological testing procedures using the dynamic shear rheometer (DSR). Learn about aging, testing variability, and modification of roofing asphalt binders.
Although the course is aimed specifically at technicians who will be testing roofing asphalt binders, other technologists, engineers, consultants, and scientists involved in the asphalt roofing industry should also benefit from the course.
Reclaimed asphalt pavement (RAP) is gained from road reconstructions; however, its usage is less optimised in Hungary and neighbouring regions, since on the project level the proportion of RAP in the asphalt mixes is only 10-15%. This is less than the recommended level in other EU countries. The higher usage of RAP provides economic and environmental advantages, decreasing the need for new materials, the transport cost, and the carbon footprint. The composition of the resultant bituminous binder blend is a critical element in the asphalt mix design with high RA content. This paper discusses the design of the resultant bituminous binder blend to provide performance and compliance characterisation. This paper also presents the complex rheological analysis of the base bitumen, the bitumen extracted from the RA and the bituminous binder blend, applying the dynamic shear rheometer (DSR) device. It was shown that for paving grade bitumen (B), polymer modified bitumen (PmB) and rubber modified bitumen (GmB), the addition of higher proportions of RA content is possible without compromising on the performance of the binder blend. With a carefully chosen paving grade bitumen it is possible to utilise up to 40% RA content. For the polymer modified bitumen, the limit of the RA content is 20%. For the rubber modified bitumen, the various proportions of RA contents showed no or negligible changes in the characteristics of the bitumen and the RA content can reach 30% in this case.
