The purpose of this manual is to serve the needs of the motoring public. Our system of paved roads and streets has developed steadily over the years. Still, the rapid increase in the number of vehicles has far exceeded the mileage of new roads added to accommodate them. Many of the older pavements are carrying motor vehicles whose volume and weight and speed are far in excess of those for which the pavements were designed. Sharp curves, steep grades, short sight distances, short vertical curves and narrow roadways are among the geometrical deficiencies that limit the pavements capacity and safety. In addition, many pavements, for various reasons, need strengthening; others need surface restoration. The objective of this manual is to propose an economical way to salvage, strengthen, and modernize deficient roads and streets with asphalt concrete.
