Recycling asphalt pavement reduces construction costs, conserves aggregate and binder, preserves pavement geometry, protects the environment, and saves energy. The handbook compiles performance data, legislation limits, selection criteria, economic analysis, and structural design guidelines for recycled pavements, and serves as a resource for a two‑day workshop on state and local government recycling guidelines. It describes hot‑mix, surface, hot‑in‑place, cold‑mix, and full‑depth reclamation recycling methods, covering materials, mix design, construction techniques, equipment, case histories, and quality control.
Recycling or reuse of existing asphalt pavement materials to produce new pavement materials has the following advantages: (a) reduced costs of construction, (b) conservation of aggregate and binder, (c) preservation of the existing pavement geometrics, (d) preservation of the environment, and (e) conservation of energy. This document was prepared to provide the following information on recycling of asphalt pavements: (a) performance data, (b) legislation/specification limits, (c) selection of pavement for recycling and recycling strategies, (d) economics of recycling, and (e) structural design of recycled pavements. The following recycling methods have been included: hot-mix asphalt recycling (both batch and drum plants), asphalt surface recycling, hot-in-place recycling, cold-mix asphalt recycling, and full depth reclamation. Materials and mix design, construction methods and equipment, case histories and quality control/quality assurance have been discussed for all recycling methods. This participant's handbook was developed to support a 2-day workshop on pavement recycling guidelines for state and local governments.
