Porous asphalt paving is a modern design method that differs from the usual pavements' traditional designs. The difference structure of porous pavements allows free passage fluids through their layers, which controls or reduces amount runoff water accumulated in area by allowing flow rain and surface runoff. cross-structure this type works as suitable for managing rainwater representing groundw...

Abstract The performance of the asphalt mixture is affected by characteristics and gradation aggregate. Polymer-modified has been widely used to overcome road pavement damage such as cracking, spalling, yielding, due deformation grooves, curling, or rutting. used, both from plastomers elastomeric types. Elvaloy modification resulted conventional mixing process 60/70 with additives Dupont that a...

The environmental impacts of producing asphalt mixtures with different percentages of asphalt binder replacement (ABR) are assessed using the technique of life cycle assessment (LCA). In this paper, only the material production phase of the pavement life cycle is considered. To improve the quality of the LCA, a regionalized life cycle inventory (LCI) database for the Northern Illinois region is...

Purpose : Identification of deformation presence or absence, fiber destruction in manufacturing asphalt concrete mixes contain ning polymer fiber. Methodology Initial dispersed reinforcing made thermoplastic fiber-forming and mineral thread, extracted from concrete, exposed to weather conditions are investigated using a weatherometer IP-1-3. Аn MIM-10 metallographic microscope is used for the a...

This report evaluates the effectiveness of rubber-asphalt and ebonite-asphalt mixes based on a review of published literature and unpublished reports. It discusses in detail various aspects of these mixes, including: diffe ent applications, physical properties, experiences of state highway agencies, and claimed advantages and problems associated with their use. The addition of ground tire rubbe...
