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...

Permeable pavements are a type of sustainable urban drainage system (SUDS) technique that are used around the world to infiltrate and treat urban stormwater runoff and to minimize runoff volumes. Urban stormwater runoff contains significant concentrations of suspended sediments that can cause clogging and reduce the infiltration capacity and effectiveness of permeable pavements. It is important...

Pavements always play a predominant role in transportation. Health monitoring of pavements is becoming more and more significant, as frequently suffering from cracks, rutting, and slippage renders them prematurely out of service. Effective and reliable sensing elements are thus in high demand to make prognosis on the mechanical properties and occurrence of damage to pavements. Therefore, in thi...

In this study, an artificial neural network was developed in order to analyze flexible pavement structure and determine its critical responses under the influence of standard axle loading. In doing so, more than 10000 four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, and subgrade soil were analyzed under the impact of standard axle loading. P...

Stone mastic asphalt (SMA) mix amended with sugarcane bagasse fibers (SBFs) as a stabilizer was investigated experimentally in the present study. The SBF content combination varied (0, 0.15%, 0.30%, 0.45% and 0.60%) to produce different mixtures. prepared mixtures were then assessed for properties, such Marshall stability, tensile strength, draindown, which are crucial performance of flexible/b...

A large amount of biomass waste is produced globally, and its production improper management are major environmental issues. Pavement industries consume amounts natural resources adversely impact the environment. Thus, utilization materials, such as biochar from biomass, has been prioritized an innovative sustainable strategy. However, there currently a paucity knowledge regarding performance i...

Abstract GPR (Ground Penetrating Radar) has been known as a tool used in non-destructive testing or other words can find out the conditions below surface without damaging layer above it. The method is generally applied to roads namely flexible pavements and rigid pavements. This properties because it utilizes electromagnetic waves its operation, such detecting presence of objects constituent la...
