The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

The road across northern Spain to Santiago de Compostela in the northwest was one of the three major Christian pilgrimage routes during the Middle Ages, leading pilgrims to the resting place of the Apostle St. James. Today, the system of trails and roads that made up the old pilgrimage route is the most popular long-distance trail in Europe, winding from the heights of the Pyrenees to the gently rolling fields and woods of Galicia. Hundreds of thousands of modern-day pilgrims, art lovers, historians, and adventurers retrace the road today, traveling through a stunningly varied landscape which contains some of the most extraordinary art and architecture in the western world. For any visitor, the Road to Santiago is a treasure trove of historical sites, rustic Spanish villages, churches and cathedrals, and religious art. To fully appreciate the riches of this unique route, look no further than The Pilgrimage Road to Santiago, a fascinating step-by-step guide to the cultural history of the Road for pilgrims, hikers, and armchair travelers alike. Organized geographically, the book covers aspects of the terrain, places of interest, history, artistic monuments, and each town and village's historical relationship to the pilgrimage. The authors have led five student treks along the Road, studying the art, architecture, and cultural sites of the pilgrimage road from southern France to Compostela. Their lectures, based on twenty-five years of pilgrimage scholarship and fieldwork, were the starting point for this handbook.
