Fig.7: Swelling in Road Pavements. Types of Failures in Flexible Pavements due to Environmental Distresses 1. Bleeding in Flexible Pavements The phenomenon of formation of a film of asphalt binder over the surface of the pavement surface is called as bleeding. The occurrence of bleeding will give a shiny glass like reflecting surface.

5 Types of Asphalt Pavement. January 2017 Asphalt is the most recycled, reused and versatile pavement material. It is used on 94% of the 2.6 million paved roads in America. There are five different types of asphalt pavement that you might be driving over. Porous Asphalt. Porous asphalt has been around since the mid 1970s.

This advancement in asphalt technology makes roads safer to use and is more environmentally-friendly. This type of road can prevent flooding and returns water to local water tables. Porous asphalt can work through up to 70% of precipitation each year, allowing it to be highly functional in damp conditions and better for the environment.
