“…This approach is known as "dynamical downscaling". A moderately complex approach, termed "statistical downscaling", is based on developing a statistical model built on historic data, which is then employed to resolve the coarse GCM future projection data (Qiao et al 2019(Qiao et al , 2020. A sketch of the steps involved is exhibited in Figure 1.…”

For the past few decades, researchers all over the world have agreed that the service life of civil infrastructure is significantly affected by climate change. Pavement is one of these significant infrastructures that can be easily affected by climate change. However, it is well known that predicting climate change is highly complex and dynamic. Hence, a review has been done on available climate change models and the uncertainties involved in climate change prediction. This review addresses various important questions such as (1) What is climate change? (2) How to use climate change models? (3) Uncertainties involved in using climate change models. (4) How does climate change impacts the pavement infrastructure? (5) What are the adaptation and mitigation strategies available? and (6) How do economic costs and emissions change due to climate change? This review is useful to understand climate change and its implications on pavement infrastructure.

“…It is a 20-year study to improve the on-site performance description of pavements [104]. Apart from this, the study introduced a new bitumen classification system called Performance Grading (PG) [105]. Consequently, the PG number helps road engineers to locate the minimum and maximum temperatures of pavement that have been selected.…”

“…The quantitative evaluation for prediction development of pavement temperature model allows for mechanistic-empirical modelling of pavement deterioration caused by climate change. However, qualitative or quantitative techniques to assess indirect impacts from climate variations, specifically to demography and traffic demand changes, should be considered in future studies [105].…”

Asphalt Pavement Temperature Prediction Models: A Review

The performance of bituminous materials is mainly affected by the prevailing maximum and minimum temperatures, and their mechanical properties can vary significantly with the magnitude of the temperature changes. The given effect can be observed from changes occurring in the bitumen or asphalt mixture stiffness and the materials’ serviceable life. Furthermore, when asphalt pavement layer are used, the temperature changes can be credited to climatic factors such as air temperature, solar radiation and wind. Thus in relevance to the discussed issue, the contents of this paper displays a comprehensive review of the collected existing 38 prediction models and broadly classifies them into their corresponding numerical, analytical and statistical models. These models further present different formulas based on the climate, environment, and methods of data collection and analyses. Corresponding to which, most models provide reasonable predictions for both minimum and maximum pavement temperatures. Some models can even predict the temperature of asphalt pavement layers on an hourly or daily basis using the provided statistical method. The analytical models can provide straight-forward solutions, but assumptions on boundary conditions should be simplified. Critical climatic and pavement factors influencing the accuracy of predicting temperature were examined. This paper recommends future studies involving coupled heat transfer model for the pavement and the environment, particularly consider to be made on the impact of surface water and temperature of pavements in urban areas.

“…Flexible road pavements account for the highest percentage of paved roads both in developed and developing countries. For instance, 94% of paved roads in the United States are flexible pavements [5] and in Kenya, flexible pavements account for 97% of all paved roads [6]. This implies the overall importance of flexible pavements in achieving effective road transport systems and asphaltic concrete is an integral component of these pavement types.…”

As the construction industry continues to evolve globally, there is a need to develop best practices geared towards achieving sustainable construction. Asphalt concrete’s demand has been increasing steadily with an estimated global demand of 122.5 million tons in 2019. This is driven primarily by the growth in construction activities in developing countries as each country works towards enhancing its transportation facilities to cater to the ever-expanding population. Hence, there are needs to develop newer and more efficient means of asphalt consumption. One of such is identifying cheaper or waste materials for use in Asphalt production. This study, therefore, examined the viability of waste marble dust (WMD), an industrial waste produced during the shaping and polishing of marble blocks and also during its extraction from the mines, as a mineral filler in Hot-mix asphalt (HMA) concrete. Engineering properties such as Marshall stability and flow, Void characteristics, Indirect tensile strength and Tensile strength ratio properties were examined. It was observed that the addition of WMD steadily increased the Marshall Stability and indirect tensile strength values and lowered the voids percentages. The study’s major finding is that waste marble dust is highly suitable as a mineral filler in HMA and a 3% by volume addition of WMD in HMA at 4.5% binder content produced the most optimal mix for use in road pavements.
