This project demonstrated that highway pavement recycling with a heater-scarifier-repaver, adding additional asphaltic material and new asphaltic concrete pavement to the mixture, can satisfactorily restore these surfaces. The proper design of new asphaltic concrete pavement material to be added was considered. The laboratory investigative work and necessary construction controls are discussed. Careful records of fuel consumption by the heater-scarifier-repaver machine were kept as were all costs attributed to the project for comparison with conventional resurfacing methods. This method of surface restoration compares very favorably economically with conventional methods.

Introductory technical guidance for civil engineers and construction managers interested in asphalt concrete pavement recycling. Here is what is discussed: 1. INTRODUCTION 2. SURFACE RECYCLING OF PAVEMENTS 3. RECYCLED COLD-MIX ASPHALT CONCRETE 4. RECYCLED HOT-MIX ASPHALT CONCRETE.
