The results of a research programme (1962-1974), sponsored by the Ministry of Public Works and carried out by the Institute of Engineering, UNAM, devoted to performance studies in three test roads, highways forming part of the national system and in a circular track for full scale road models are presented. The utilization is recommended of a criterion developed by the Institute for the evaluation of the structural strength of flexible highways, together with non-destructive deflection tests for road zoning in the case of reconstruction. The experimental basis of the recommendations is presented. The results of studies into performance vs maximum elastic deflections are analyzed and it is concluded that no adequate correlation between them exists. The inclusion of complementary information in the analyses is recommended, such as radius of curvature, structural characteristics, geotechnical aspects of the zone, and so on, to ensure theoretically more reliable correlations. /Author/
