Permeable pavement surfaces may be composed of; pervious concrete, porous asphalt, paving stones, or interlocking pavers. [1] Unlike traditional impervious paving materials such as concrete and asphalt, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below.

Pervious concrete was first used in the 1800s in Europe as pavement surfacing and load bearing walls. [3] Cost efficiency was the main motive due to a decreased amount of cement. [3] It became popular again in the 1920s for two storey homes in Scotland and England. It became increasingly viable in Europe after WWII due to the scarcity of cement.
It is the cetacean with the greatest appetite for human interaction and the most commonly used dolphin in dolphinariums. [31] Although the Bottlenose dolphin is the most abundant cetacean species in the Mediterranean, its population is in a slight decline. [32] It can be found along the coasts of the entire basin. [17]
Tarmacadam is a concrete road surfacing material made by combining tar and macadam (crushed stone and sand), patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 19th century.
