The HDM-4 aids in estimating the deterioration of pavement as well intricate interactions between environment, vehicles, surface, and structure pavement. It predicts how roads will deteriorate over time due to increased traffic. current study was carried out at Hyderabad, particularly which are subjected heavy adopted for Dhulapally Bahadurpally (DB), Gandimaisamma Bowrampet (GB), Medchal (GM),...

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

The use of falling weight deflectometer—based backcalculation techniques to determine pavement layer moduli is a cost-effective and widely used method for the structural evaluation of an existing pavement. The nonlinear stress-sensitive response of pavement geomaterials has been well established, and mechanisticbased pavement design can be improved by inclusion of these nonlinear material prope...

To measure stiffness of the compacted pavement, practitioners use the Compaction Meter Value (CMV); a ratio between the amplitude for the first harmonic of the compactor’s acceleration and the amplitude corresponding to the vibration frequency. Numerous experiments show that CMV is highly correlated with the pavement stiffness, but as of now, there is no convincing theoretical explanation for t...

Among the urban societal burdens rolling noise generation from tire pavement interaction and waste stand apart. Many materials can be used in pavements with comparable mechanical performance. Noise-related characteristics such as porosity, sound absorption surface texture, were measured for semi-dense low mixtures using namely: recycled concrete aggregates, crumb rubber, polyethylene terephthal...

ABSTRACT: Most pavement maintenance management systems tend to be either non-analytical databases or statistical correlation models. However, pavement maintenance is part of a complex system (comprising the road pavement, the environment, diverse users, the maintenance authority and Local/State/Federal Governments) that has significant feedbacks, making it a suitable field for system dynamics e...
