Article
The use of phase change materials (PCMs) to regulate pavement temperatures has been previously studied, with the most successful studies using porous aggregates to stabilize the PCMs. However, this technique can lead to issues with PCM leakage and low PCM content. A less studied method is the use of PCM microcapsules, which also presents challenges...
Article
The accumulation of snow and ice formation in asphalt pavement riding surfaces plays a critical role in the direct contact of the roadway with vehicle traffic. Considering the importance of this matter to vehicle transportation safety and other pavement performance concerns, Phase Change Materials (PCMs) have emerged as a potential solution to make...

Environmental conditions are considered an important factor influencing asphalt pavement performance. The addition of modifiers, both to the asphalt binder and the asphalt mixture, has attracted considerable attention in potentially alleviating environmentally induced pavement performance issues. Although many solutions have been developed, and som...
Chapter
The traditional Superpave mixture design method selects optimum asphalt binder content to yield 4% air voids content in asphalt mixtures, while anticipating approximately 7% air voids content at the time of construction. This approach can produce mixtures with high ageing and moisture damage potential. A recently developed mixture design method nam...

In spite of its economic and environmental benefits, the use of reclaimed asphalt pavement (RAP) is limited due to the impact of aged binder on the performance of asphalt pavements. Currently, one of the most popular methods to mitigate the aged RAP binder is the addition of a rejuvenating agent. Such an agent acts to restore life to the aged binde...

Potholes are a common pavement distress, particularly appearing during the spring freeze-thaw period in northern climates. Such holes reduce ride quality, and if left unrepaired can lead to rapid pavement deterioration. The reactive approach to repairing potholes can often be too late to prevent further pavement damage and also makes it difficult f...

Since 1996, warranted asphalt pavements have been placed on a trial basis in Indiana in an attempt to improve pavement performance, increase quality, and prevent premature failures. The initial capital costs of these pavements have been higher than those of similar nonwarranted asphalt pavements, however. Because of this, an assessment of the benef...

Low-volume roads constitute the vast majority of the U.S. road network. From an economic standpoint, preservation of low-volume roads costs more than $80 billion per year, or more than half the annual investment in roads. Although low-volume roads carry a small percentage of the overall traffic, their associated crash rates are considerably higher...

Major highways are designed to withstand heavy vehicles and high volumes of traffic year round. However, low-volume roads in seasonal frost areas are highly susceptible to damage from trafficking by heavy vehicles during spring thaw. Conventional practice is to place partial or full spring load restrictions on low-volume roads during spring thaw. T...
