Abstract. In Canada, sustainable transportation strategies such as changes in vehicle technology, travel patterns and fuel have been made to reduce vehicle emissions and their impacts on human health and the environment. However, recent studies show that pavement surface condition can have significant effect on transportation fuel consumption and emissions. The rolling resistance effect that...
Abstract. The Lifecycle Cost Analysis (LCCA) is an essential tool highway officials use to evaluate the merits of different pavement design alternatives and make suitable transportation investment decisions. However, the LCCA uses inputs that are inevitably highly uncertain. The deterministic LCCA approach is easy, uses average input values, and is straightforward to determine the low-cost...
Abstract. In the context of sustainable road construction, this study con-ducts a Life Cycle Assessment (LCA) to evaluate the environmental impact of an innovative asphalt mixture incorporating Steel Slag Aggregate (SSA) and Reclaimed Asphalt (RA), with a specific focus on the production phase. The research compares this innovative mixture with a conventional one uti-lizing Natural Aggregate...
Abstract. The use of titanium dioxide (TiO2) nanoparticles on asphalt pavements as surface coating has been the subject of study since these coatings can degrade air pollutants through a photocatalytic process. However, the environmental impacts associated with the functionalization of nanoparticles on the pavement are still unknown. Therefore, this research aims to perform a Life Cycle...
Waxes have long been used as rheological modifiers in warm mix asphalt, reducing viscosity at high temperatures and improving workability. Vari-ous percentages of Sasobit (S) and two types of Polyethylene waxes (PEQ and PEG) were used, ranging from 1% to 5% by mass. The rheological prop-erties of the binder were evaluated by mechanically blending the binder at speeds ranging from 1000 to 2000...
This study delves into a novel area of research, exploring the implications of zeolite in Warm Mix Asphalt (WMA) on compactability indices and moisture damage. The investigation focuses on the impact of aging time and workability properties on WMA mixtures, utilizing compactability to determine production temperatures. Two distinct approaches were employed to assess workability properties:...
