Challenges and solutions for crack sealing in asphalt

Surface cracking in asphalt concrete is a major failure mechanism that develops over the pavement service life. In general, surface cracks are primarily caused by traffic loading and temperature variations [1]. It is well recognized that water infiltration through cracks may accelerate pavement deterioration resulting in major problems such as moisture damage, base failure, and potholes [2; 3].

Rubber modified binders as an alternative to cellulose

Abstract The introduction of fibers in SMA mixtures to prevent binder drainage complicates work in the mixing plants and generates additional costs. It is therefore interesting to define techniques in order to dispense with the fiber without taking further risks concerning binder drainage during construction or plastic deformation during road life service. In this research paper, two SMA 11

Rubberized asphalt mixtures: a novel approach to pavement

Rubberized asphalt pavements have increased viscosity, or stiffness, at high pavement temperatures to reduce permanent deformation. The increased flexibility of rubberized asphalt at lower pavement temperatures minimizes cracking as a result of low temperatures. Increased durability of rubberized asphalt pavements comes from an increase in
