Deterioration empirical modelling of asphalt to Malaysian weather and traffic in Plus Bhd / Mohd Zamir Mohd Zoraini

Highways are crucial for providing personalized and efficient passenger transportation services. Highways can increase traffic demand, promote socio-economic development, and enhance quality of life. Economic growth is rapidly increasing, but at the same time transportation patterns also change as the economy expands. Asphalt pavement deterioration can be caused by various factors, including traffic, construction, materials, environment, and age. These factors influence the pavement's condition and longevity. There is a lack of research on the condition of flexible pavement condition under influence of traffic loading in equivalent standard axle units and precipitation in highway. The purpose of this research is to determine deterioration empirical modelling of asphalt to Malaysian weather and traffic loading.2-year timeframe was chosen to provide a thorough and inclusive dataset that encompasses a wide range of meteorological and traffic variables that impact the pavement. The study's results also indicated that the condition of the pavement worsened as traffic volume grew, and the most significant climatic factors were precipitation, which aligns with previous studies. While previous research highlighted the significance of rain precipitation, the results of this investigation revealed that precipitation exerted a more substantial impact. Prior studies on pavement degradation have predominantly concentrated on the isolated effects of traffic or meteorological conditions on pavement conditions. The main objective of this research was to evaluate the separate and combined effects of traffic loads and precipitation conditions on the long-term condition of the pavement. According to this study, this study is crucial for accurately estimating the quality of pavements in metropolitan areas. This, in turn, allows for better anticipation and prioritization of maintenance and rehabilitation efforts. This research aims to assist highway administrations in transitioning from reactive maintenance practices on rural road networks to proactive maintenance practices on urban roads.
