One of the objectives within European research project CoRePaSol (supported CEDR Transnational Program) was to summarize assessment and stiffness modulus cold recycled mixes determined according repeated indirect tensile stress test (IT-CY). In most cases values were compared strength (ITS), which is currently commonly used characteristic for proving quality a mix. The first part experimental measurements focused on standard mixes, thus whose aggregate skeleton formed entirely by RAP contain...
The influence of different aggregate skeleton matrices, as well volumetric composition and mixture stiffness, on the resistance SMA to permanent deformation was assessed. Nine with optimised studied elsewhere, were now evaluated wheel tracking. results statistically analysed concerning relationship specimens' characteristics, Marshall properties stiffness. Aggregate dry rodded compaction tend produce asphalt mixtures similar designed pre-established grading envelopes. Proctor steel roller...
This paper presents the concepts for application of space vector modulation to two-level unidirectional pulsewidth (PWM) rectifiers, and a methodology use this is proposed applied in three different groups rectifiers. For each group converter switching stages are analyzed determine switch control signals modulation. One sequence all rectifiers order minimize number commutations reduce losses. Duty cycle functions determined, desired sequences performed by simple PWM, without need present...
Traditionally Stone Mastic Asphalt (SMA) is empirically designed, which could not guaranty an adequate stone-on-stone effect. To overcome this drawback, a research study was carried out having in view to develop new SMA mix design approach for the optimisation of effect, based on findings. end, included only evaluation volumetric characteristics test specimens, but also coarse aggregates (CA) prepared using different aggregate compaction methods: (i) bulk particles' specimens (compaction...
This work presents a methodology to apply space vector modulation three-phase three-switch two-level Y-connected unidirectional PWM rectifier. Converter switching stages are analyzed determine switches control signals for modulation. A sequence is proposed minimize the number of commutations. Rectifier models and structure also described. In order validate modulation, experimental results presented 20 kW prototype.
Bitumen is the most common binder used in production of bituminous mixtures for road paving, having a fundamental influence on performance pavement. However, it not yet fully understood which bitumen properties have significant behaviour mixtures. In this context, FunDBitS project was developed. Its main objective to prepare recommendations be specified order obtain suitable mixtures, namely what concerns its resistance permanent deformation (rutting), stiffness, low temperature cracking,...
The paper describes the uncertainty evaluation related to dynamic measurement of deflections using a falling-weight-type impulse load device. This equipment is used in road and airfield pavements in-situ testing, contributing for assessment their performance analysis characterization. study aims at determination deflection uncertainty, following GUM approach, where quantities are considered constant time, its comparison with results obtained from recently developed approaches dedicated...
