PAVEMENT SURFACE QUALITIES /IN SPANISH/

A STUDY IS MADE OF THE CHARACTERISTICS REQUIRED OF A MODERN HIGHWAY IF IT IS TO OFFER SAFETY AND COMFORT TO USERS. SURFACE CHARACTERISTICS MUST BE ACHIEVED AT LOW COST AND LAST AS LONG AS POSSIBLE. SAFETY IS ENSURED IF A DRIVER CAN CONTROL HIS VEHICLE ON A CURVE ON A GIVEN TRAJECTORY. COMFORT WILL BE AT ITS MAXIMUM IF THE PROFILE OF THE HIGHWAY HAS NO IRREGULARITIES WHICH CAN CAUSE VERTICAL VIBRATIONS. THE LIFETIME OF THE HIGHWAY WILL BE LONG IF, UNDER DYNAMIC TRAFFIC CONDITIONS, BRAKING AND MANOEUVERS CAN BE CARRIED OUT SATISFACTORILY AND IF SUDDEN DEFORMATIONS OF THE PROFILE DO NOT OCCUR. SAFETY AND COMFORT DEPEND ALSO ON FACTORS SUCH AS GENERAL ALIGNMENT CHARACTERISTICS AND RAPID AND SATISFACTORY DRAINAGE. BRAKING IS CLOSELY RELATED TO THE COEFFICIENT OF FRICTION, MANOEUVERS TO THE COEFFICIENT OF MANOUVERABILITY, AND COMFORT TO GEOMETRIC IRREGULARITIES. SAFETY IS LINKED WITH ALL THE ABOVE PARAMETERS, AND LOSS OF ADHESION AND VARIATIONS IN THE MANOEUVERABILITY AND FRICTION COEFFICIENTS FROM ONE POINT TO ANOTHER. /TRRL/
