COMPARATIVE PERFORMANCE OF PAVEMENT MIXES CONTAINING CONVENTIONAL AND ENGINEERED ASPHALTS

Results of a comprehensive laboratory evaluation of asphalt and pavement mixes containing conventional and engineered paving binders are presented. Model pavement structures were constructed and tested under full-scale dynamic loads and high temperatures simulating field conditions for rutting evaluation. Pavement rutting was monitored over hundreds of thousands of load cycles simulating long-term performance. Comparative results on pavement temperature susceptibility and low-temperature behavior of various conventional and engineered asphalt mixes are presented. Pavement temperature susceptibility is evaluated by determination of resilient moduli at various test temperatures. Low-temperature performance is evaluated by determination of pavement stiffness values derived from direct tension tests carried out at very slow speeds. Conventional physical properties and the Strategic Highway Research Program's performance characteristics on test asphalts are presented and discussed in relation to actual measured performance. Analysis of test results identified three asphalt characteristics of particular importance for good performance; all are measured on the aged thin-film oven test residue including asphalt viscosity at 60 deg C, low-temperature penetration at 4 deg C, and asphalt temperature susceptibility.
