In this paper, annoyance ratings from traffic noise recorded on cobblestones, dense asphalt, and open asphalt rubber pavements are assessed with regard to car speeds and traffic densities. It was found that cobblestones pavements are the most annoying; also while open asphalt rubber pavement imposes less annoyance than dense asphalt it is not significantly different. Higher car speeds always le...

The performance of Styrene-butadiene-styrene (SBS) modified asphalt is closely related to the content SBS modifier. In production process asphalt, a certain amount additive such as sulfur and rubber oil may be added reduce segregation promote swelling polymer, but effect these additives on determining in not yet clear. This paper presents calibration curves based rutting factor creep slope poin...

Stripping is one of the major distresses within asphalt concrete pavements caused due to penetration water interface asphalt-aggregate matrix. In this work, grade cement (40-50) was mixed with variable percentages three types additives (fly ash, fumed silica, and phosphogypsum) obtained an modified resist effect stripping phenomena .The specimens have been tested for physical properties accordi...

Warm Mix Asphalt (WMA) is a set of technologies that uses additives to reduce binder viscosity and increase mixture workability, which provides complete coating aggregates at lower temperatures around 100 °C 130 °C. Organic wax or Sasobit one the can be used for this purpose. It reduces melting point wax, allows production asphalt mixes temperatures. This attempt proposes new relationships elas...

The stability of asphalt concrete under the effects of freezing and thawing was studied experimentally, and the experimental test results were modelled using fuzzy logic and statistical methods. The stability was investigated experimentally using the Marshall and ultrasound methods. Asphalt core samples 10 cm in diameter were alternately frozen (–20°C for 16 hr) and thawed (16°C for 8 hr) for 5...

In China, the construction of asphalt pavement has a significant impact on the environment, and energy use and greenhouse gas (GHG) emissions from asphalt pavement construction have been receiving increasing attention in recent years. At present, there is no universal criterion for the evaluation of GHG emissions in asphalt pavement construction. This paper proposes to define the system boundar...

Waste utilization has gained more and more interest. In this study, crumb rubber and diatomite were used to modify asphalt binder and the short-term aging effects on the properties of modified asphalts were evaluated. Three kinds of modified asphalt were prepared; they are diatomite modified asphalt (DA), crumb rubber modified asphalt (RA), and diatomite and crumb rubber compound modified aspha...
