Concrete, sulfur fatigue

In conventional asphalt concrete mixes, for which stability is a foremost consideration, the design asphalt content is generally close to the optimum asphalt content for fatigue life. In aggregate-asphalt-sulfur mixes the significant mix properties should be considered independently... 

Discussion of Results. The results of the relative fatigue life analysis of the four pavement sections are given in Table X. The analysis indicates that the 12-in. asphaltic concrete pavement (System 1) and the 1%-in. sulfur-asphalt over 10-in. asphaltic concrete base (System 4) were not able to withstand the 106 passes of an 18-kip axle load. For System 4, the iy2-in. S-A-S surfacing was adequate, but analysis indicated that...
