“Improving the Performance of Highways and Airports Flexible Pavement to Resist the Effect of Octahedral Shear Stresses”
Abstract
It has been acknowledged that, the rheological properties of asphalt binder as aviscoelastic material, play an important role in regulating cohesion and internalfriction of hot mix asphalt (HMA), in integration with aggregates interlocking, toprotect the asphalt concrete pavement (ACP) surface layer against any inadvertentloads. Due to the recent worldwide increase in the combination of individualwheel load (IWL) and tire pressure of the new-type aircraft, shear relateddistresses have been observed in some Egyptian airfields. Top-Down cracks(TDCs) have been also reported as one of the most surface deterioration in thisperspective. Moreover, creep has been arising in ACP especially, in southernlatitude airports, where surface layer is exposed excessively to high temperatureambient. In this decade, the criterion of admissible octahedral shear stresses(OSSs) in the flexible surface layer, has been used successfully as a judiciousdesign tool, for the accurate assessment of ACP performance. Consequently, theaim of this work, was to study the impact of using bitumen products throughdifferent two Egyptian companies (Alex and Suez), modified by recycled lowdensity polyethylene (LDPE), on the OSS resistance of ACP surface layer. OSSrelated rutting and cracking criteria of HMA have been subject to intensiveevaluation in the light of mechanistic-empirical (M-E) methodology. In thiscontext, a number of simple performance tests (SPTs) such as, flow number (FN)test, dynamic modulus (E*) test and tri-axial compression test have been appliedon typical dense-graded HMA samples, “which were designed by MarshallMethod”. The obtained E* results were compared to other data estimated byIII standard E* predictive mathematical models such as Hirsch, Witczak (1-37A) andWitczak (1-40D), to evaluate their capabilities of simulating the virgin andmodified HMA at the design level. Master curves analysis of OSS parameters, hasrevealed a significant enhancement of performance grade (PG) as well as ACPsurface significant resistance to OSS and rutting, after LDPE modification, inagreement with the traditional empirical and rheological indices.
