BITUMINOUS MIXTURES WITH TRINIDAD ASPHALT AS AN ADDITIVE. EXPERIMENTAL RESEARCH FOR AIRPORT PAVEMENTS

SUI CONGLOMERATI BITUMINOSI ADDITIVATI CON ASFALTO TRINIDAD. RICERCHE SPERIMENTALI PER LE APPLICAZIONI AI MANTI DI SOVRASTRUTTURE AEROPORTUALI

Trinidad asphalt has recently been used as an additive in bituminous mixtures for airport pavements (parking areas at the head of the runway at Munich and Bremen airports, Germany). A section of the Rome outer ring road which carries intense traffic containing a high percentage of heavy vehicles, has also been experimentally paved with this type of mixture. In comparison with conventional mixtures, results have shown an appreciable improvement in mechanical characteristics (stability and resistance to wear), and in resistance to the aggressive action of aircraft fuels. The mixes containing Trinidad asphalt maintain their stability and viscosity through temperature variations, and provide good skid resistance. This article gives an indication of the optimum percentages of Trinidad asphalt to be used, as obtained from the results of laboratory tests. /TRRL/
