Scitus Academics Asphalt Pavements by Devendra Damale
Asphalt pavements are easy to maintain, quick to construct, and provide a safe, smooth, quiet ride. Simply put, asphalt pavements provide the greatest level of drivability at the most economical price. Asphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. Asphalt cement is heated aggregate, combined, and mixed with the aggregate at an HMA facility. Asphalt is America’s most recycled material. Reclaimed asphalt is not just reusable as a “black rock” – the asphalt cement in the reclaimed pavement is reactivated to become an integral part of the new pavement. The recycled asphalt cement replaces part of the new asphalt cement required for the pavement, reducing costs for road agencies.Recycling is just one reason that asphalt is the most sustainable pavement. Asphalt pavements that are designed and constructed as Perpetual Pavements never need to be removed and replaced. They are permanent structures. The only maintenance needed is infrequent replacement of the surface – and the material that is removed is recycled.This book focuses on asphalt pavement management, processes, operations, methods and techniques. Asphalt recycling also has been pointed out.
