Skateboards ride again Thanks to the parents who cruised and bruised themselves on pavements 30 years ago, the sport of the teenage dropout has come of age.
Since the American Association of State Highway Officials AASHOO) road test, the fourth power law has been widely used by pavement engineers to design highway and airfield pavement and to predict the remained life and cumulated damage of pavements [1, 2, 3].
Some researchers have even reduced the PSD curves to only two families: one for rigid (cement concrete pavements), and the other for flexible (asphalt concrete pavements) [25, 26].
In the United States, the Environmental Protection Agency has developed a three-prong approach of (1) cool pavements, (2) urban forestry and (3) cool roofs to mitigate the UHI.
Furthermore, the optimal low-impact development found for this case study includes 0.2 km2 of permeable pavements, 0.1 km2 of rain barrels and 0.7 km2 of green roofs.
A significantly greater percentage of light activity (24.1%) compared to moderate (20.0%) and vigorous (17.9%) was undertaken in buildings (p<0.001) equating to an average of around 15 min more per child per day, and on roads and pavements (13.2% vs 11.8% and 9.1%, p<0.001) equating to around 7 min more per day.
Mostly, streetlights, highway guardrails, and pavement markings [27, 28, 29, 30] have been investigated.
This can be a crucial element leading to a more precise dynamic analysis of pavement structures [54, 73, 74].
It has been concluded that modified asphalt by additive can significantly improve the asphalt pavement performance [8, 9, 10].
