| dc.description | Summary: This report describes visual observations of the behavior of in-place rubberized-tar concrete pavements at fourteen Air Force bases, and results of laboratory tests on core specimens obtained from these pavements to determine their condition after exposure to traffic, jet heat and blast, jet-fuel spillage, and weathering in various climatic zones. The core specimens were subjected to density, stability, extraction, and gradation tests, and void relations were computed. The gradation and extraction tests cannot be considered entirely reliable as it was impossible to separate the binder and aggregate completely. Surface cracks and open construction joints were found at all of the sites investigated. Types of cracks noted were : (A.) reflection, (B.) shrinkage, (C.) crazing, and (D.) overload. The cracking varied from minor hairline to openings 1/2 in. wide. The pavements generally began to crack about the first or second winter after being placed. They usually had received little or no aircraft traffic by this time . At one site the cracking appeared to be retarded somewhat after application of traffic and, although cracking continued, the pavement did not reach a condition considered unsatisfactory for traffic. Fuel spillage apparently caused only insignificant damage, and the pavements were withstanding the blast from jet aircraft very well. Visual observations indicated little or no relative difference in performance of the three rubberized-tar binding agents used in the pavements, Flintbinder C-2, Surfa-aero-sealz, and Jetlock. The major defect in rubberized-tar concrete pavements is their tendency to harden rapidly and crack, apparently as a result of evaporation and sublimation of constituents of the binder. A seal coat applied soon after construction should alleviate this tendency. | - |
