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 ...

Abstract In order to solve the problem of high-value utilization coal-to-oil residual direct coal liquefaction asphalt, it is compounded with SBS and aromatic oil modify matrix 9 compounding schemes are designed using orthogonal experimental methods. Dynamic frequency sweep tests DSR a simplified Carreau equation model fitted complex viscosity obtain its zero shear viscosity; creep recovery rat...

Asphalt is a kind of temperature-sensitive material. With the decrease temperature, deformation capacity an asphalt mixture will be significantly reduced. When temperature greatly reduced, layer produce large shrinkage tensile stress and strain, resulting in cracking. Therefore, cracking resistance behavior essential for asphalt. In order to study geosynthetics-reinforced under lower temperatur...

In this work, the objects of research are cement asphalt concrete obtained on basis binder and bitumen emulsion, using as mineral additives, waste from thermal power plants, in form fuel ash various types. The analysis foreign domestic literature topic is carried out. order to reduce amount inorganic (cement) consumed, well modification organic (bitumen emulsion), ashes two producers, CHP-2 CHP...

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 ...

Hot mix asphalt has various benefits such as good workability and durability. It is one of the most general materials used mixtures in road pavements. Asphalt binders can be improved by modifying them with additives. Gilsonite a natural hydrocarbon which may an additive to hot asphalt. binder modifier (wet process) mixture (dry improve properties mix. provides option rheological properties, sta...

Many factors influence a vehicle’s rate of fuel consumption. Among them are engine efficiency, speed, aerodynamics, and rolling resistance. When it comes to the influence that pavement characteristics have on fuel consumption, one of the major contributors is surface roughness which impacts rolling resistance; more energy is required to propel a vehicle over a rough surface than over a smooth s...
