The damage to highway facilities followed by large earthquakes causes consequential socio-economic damage, since the damage spoils transportation systems. From this point of view, the repair of damaged highway facilities would be one of the most important factors for the social rehabilitation after eqrthquakes. In conducting countermeasures such as aseismic design, highway planning, and road administration, it is also important to cosider the indirect effects of damage to highway facilities. This report discusses the problems of rehabilitation of highway networks after earthquakes. And, some precedents for the damage to highway networks after earthquakes are surveyed minutely. Data from the Niigata Earthquake of 1964, the Izu-Ohshima kinkai Earthquake of 1978, the Miyagiken oki Earthquake of 1978, and the Urakawa oki Earthquake of 1982, are presented. From the study, a concept of countermeasures of rehabilitating highway networks with view of seismic damage, a definition of periods after the outbreak of an earthquake, and characteristics of highway traffic from each period, are clarified.
