Special Issue Information

Dear Colleagues,

Asphalt or bitumen is the principal element of almost 95 percent of road pavements in all countries. Although the quantity of asphalt binder in a mixture is only 4–6 percent, it greatly influences the mechanical and performance properties of the bituminous mix. Asphalt has been used so extensively in roads that researchers are now developing alternative binders as the natural asphalt originates from non-renewable and exhaustible resources. Many new methods of reducing the consumption of natural binder are being explored. These include the development of bio-binders, the utilization of RAP, the emulsion-based construction of roads, and many more.

This Special Issue on Sustainable Binders for Roads aims to collate original research and review articles on sustainable asphalt binder in the fields of highway engineering and pavement technology. Research articles on a wide variety of subjects, including the development of bio-binders, the characterization of new binders, the field performance of pavements constructed with new binders, the use of recycled asphalt binder, the chemistry of alternative binder, and morphological characterization of binder, are invited for this issue. All papers should conform to the theme of the sustainability. 

Potential topics include, but are not limited to, the following:

  • The rheological properties of bio-binders for asphalt pavements;
  • The chemistry of alternative binders relevant to pavement performance;
  • Asphalt Mix design with alternative binders;
  • Field studies with high amount of RAP;
  • Pavement performance;
  • Testing protocols for new binders and asphalt mixtures.

The study presented in this paper investigates the application of asphalt bitumen modification using a fast-reacting SBS polymer at a low modifier percentage. The hypothesis is that a fast-reacting styrene–butadiene–styrene (SBS) polymer that composes only 2% to 3% of the weight of the bitumen modification could extend the life of the pavement surfacing and pavement performance at relatively low input costs, increasing the net present value produced by the pavement during its life cycle. To confirm or refute this hypothesis, two types of road bitumens CA 35/50 and 50/70 were modified with low amounts of fast-reacting SBS polymer with the expectation of attaining properties similar to a 10/40–65 modified bitumen. For each type of unmodified bitumen, bitumen modification and comparative 10/40–65 modified bitumen, the following tests were conducted: needle penetration, softening point—ring and ball test method, and ductility test. The second part of the article focuses on a comparison of asphalt mixtures with different compositions of coarse-grain curves. For each mixture, complex modulus with varying temperatures and fatigue resistances are represented by the Wöhler diagram and compared. Based on in labo testing, the impact of the modification on pavement performance is evaluated. Life cycle changes for each type of modified and unmodified mixtures are quantified as road user costs, and attained benefits are compared with increased construction costs. Full article
