The ability to classify asphalt surfaces is an important goal for the selection of suitable non-variant targets as pseudo-invariant targets during the calibration/validation of remotely-sensed images. In addition, the possibility to recognize different types of asphalt surfaces on the images can help optimize road network management. This paper presents a multi-resolution study to improve aspha...

The use of recycled materials in pavement construction has seen, over the years, a significant increase closely associated with substantial economic and environmental benefits. During the past decades, many transportation agencies have evaluated the effect of adding Reclaimed Asphalt Pavement (RAP), and, more recently, Recycled Asphalt Shingles (RAS) on the performance of asphalt pavement, whil...

To determine the behavior of hot mix asphalt including different penetration grade bitumen has been a major subject of paving engineering. In this study the effects of different penetration grade binders on the mechanical properties of hot mix asphalt were investigated with four different tests. The specimens prepared with AC-5, AC-10, AC-20 and SBS modified AC-10. The stiffness modulus, creep ...

The Indirect Tension Test (IDT) is frequently used for evaluation of asphalt material viscoelastic creep properties. With the increased use of finer aggregate gradations and polymer modified asphalt binders in asphalt materials, crushing can occur under the narrow loading heads. The new specimen configuration proposed has a trimmed area under the loading heads, creating a “flattened-IDT.” This ...

an experimental program was conducted to determine the effects of geosynthetic reinforcement on mitigating reflection cracking in asphalt overlays. the objectives of this study were to asses the effects of geosynthetics inclusion and its placement location on the accumulation of permanent deformation. to simulate an asphalt pavement overlaid on top of a crack in a concrete or asphalt pavement, ...

Permeability of an asphalt pavement is one of the most important parameters that have a direct influence on its design life. It is an intrinsic property that relates the average fluid velocity to a constant pressure gradient; however, the external pressures on a saturated pavement pore structure are often dynamic due to the repeated tire loading in the field. A dynamic permeability constant, th...

As a fair deck pavement material of its kind used in steel bridge, the epoxy asphalt concrete is considered much more superior to ordinary asphalt concrete in terms of road performance, while still greatly subject to the level of design and construction. Starting from a practical case of the epoxy asphalt concrete that has been applied in the deck pavement of Pingsheng Steel Bridge, this paper ...

this paper is a state-of-the-art in sulphur-asphalt (sa) design technology based on a comprehensive analysis of current practice and technical literature, in order to investigate the possible use of sa pavements in iran. in this paper, the major aspects(material, technology, properties, production, placement, quality assurance, design, and field varification) of sa pavements are considered. fer...

This research aims to define an efficient and fast quantification of bitumen removal on the road surface by Digital Imaging Processing (DIP) and spectral analysis. The retrieval of bitumen removal is an important issue for road management and environmental studies related to asphalt wear and environmental pollution. The calculation of the Exposed Aggregate Index (EAI), based on DIP, allows to q...

This chapter describes the methodology used in EPA’s Waste Reduction Model (WARM) to estimate streamlined life‐cycle greenhouse gas (GHG) emission factors for asphalt shingles beginning at the waste generation reference point. The WARM GHG emission factors are used to compare the net emissions associated with asphalt shingles in the following four waste management alternatives: source reduction...
