MANITOBA TEST HIGHWAY IS WIRED TO INVESTIGATE TRANSVERSE CRACKING OF ASPHALTIC PAVEMENT

A THREE-MILE SECTION OF THE TRANS-CANADA HIGHWAY IS SAID TO BE THE MOST HEAVILY INSTRUMENTED ROAD IN NORTH AMERICA. IT IS DESIGNED TO STUDY TRANSVERSE CRACKING, A PROBLEM THAT IS GENERAL ON ASPHALTIC SURFACES IN COLD CLIMATES. THE SITE WAS CHOSEN BECAUSE IT PERMITTED HALF THE ROAD CONSTRUCTION ON CLAY SUBGRADE AND THE OTHER HALF ON SAND SUBGRADE. ASPHALT MIXTURES, DEPTHS OF PAVEMENT, AND THE SUBGRADE DIFFER IN EACH 400-FT SECTION. AUTOMATIC RECORDING EQUIPMENT MONITORS THE SITE CONTINUOUSLY, AND READINGS WILL BE TAKEN FOR AT LEAST TWO YEARS.
