Considerable attention has also been paid to measuring resilience but connecting measures of resilience to decisions has received little attention. Using the concept of resilience also raises many questions. What does resilience mean for life cycle cost? Is resilience just another level of service, or performance measure? How does resilience recognize the number of users affected by a disruption? Is resilience an appropriate metric for an objective function or is resilience part of multi-attribute decision making? How does resilience relate to sustainability? Is resilience the complement of vulnerability? Drawing on case studies that apply pavement performance as a measure of resilience, the results show that different measures and indicators are applicable for different types of decisions.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115737070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pursuing these goals, this study investigates innovative and green extended bituminous binders. The new binders are obtained replacing different percentages of neat bitumen, up to 44 wt.%, by combining different amounts of three recycled products: Re-refined Engine Oil Bottom, powdered rubber from End-of-Life tyres and a waste bentonite filler. At first, a rheological characterisation of these binders was performed using a Dynamic Shear Rheometer. Subsequently, they were used to manufacture asphalt mixtures. The Indirect Tensile Stiffness Modulus, Indirect Tensile Strength and volumetric analysis of samples were carried out to evaluate their potential performance in road applications. The experimental program has allowed to understand how changes in constituents materials affect the rheological responses of binders and the mechanical properties of asphalt mixtures, providing promising results.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115342745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is caused by horizontal tensile strains generated at the tire-pavement contact area. This paper, adopting the principal of Foundation Surface Modulus (FSM), determines the thickness of the asphalt layer having a uniform stiffness modulus or two different stiffness moduli (surface course and rest of asphalt layers), above which TDC will be the predominant deterioration mechanism in comparison to the bottom up cracking. The findings concluded that, in the case of uniform asphalt stiffness, when the thickness of the asphalt layers is greater, or less than, depending on the magnitude of FSM and asphalt stiffness, approximately 210 mm, 250 mm, 220 mm and 330 mm, for the above-mentioned axle loads respectively, the flexible or semi-flexible pavement will fail due to top-down cracking and not due to bottom up cracking. Different behavior exists when the stiffness of the wearing course (S1) varies in comparison to the stiffness of the rest of asphalt layers (S2). In this case when the ratio S1/S2 is less than 1.0 the TDC is the most likely type of failure in almost all cases.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124569870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the engineer must have a global knowledge of the technologies not only to reduce maintenance costs, that can cause an accident risks, but also to deal with a foreign regulation. This paper aims to discuss permanent deformation and irregularities on asphalt pavements of runways, highspeed exit, taxiways, and aprons. When the pilot use pedals to apply the wheel brakes, all kinetic energy is transferred to the pavement, which can damage the flexible surface resulting on rutting and roughness. Rutted areas accumulate rainwater, more often in tropical regions, and pose hydroplaning hazards. Finally, the longitudinal joint of an asphalt pavement can generate cracking and failure if positioned within the path of landing gear wheels. Hence, this paper presents the causes and the possible ways of avoiding airfield accidents, while still in the design phase.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129229204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several laboratory aging methods have been developed in order to examine the effect of aging to the properties of asphalt mixtures. This study examines the effect of oxidative aging to characteristic properties of a semi-open asphalt concrete with blast furnace slag aggregate using three types of bitumen. The bitumens used were a 35/50, a 50/70 penetration grade bitumens and an SBS modified bitumen. Short and long-term oxidative aging of the three resulted asphalt concrete mixtures has been carried out on loose mixtures. The mixtures characteristic properties examined were: stiffness, indirect tensile strength and indirect tensile strength ratio. Penetration and softening point were also determined before and after oxidative aging. Results showed that oxidative aging had lesser effect on the characteristic properties of the AC mixture with the SBS bitumen. The water sensitivity of the mixtures was not affected by oxidative aging in all cases. Oxidative aging had lesser effect on penetration and softening point of the SBS modified bitumen in comparison with the other two types of bitumen.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131376851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equation for the calculation of the stiffness includes the Poisson ratio and it could be demonstrated that the influence of this value on the stiffness result is very significant. The Semi Circular Bending test (SCB) is used for the determination of fracture and fatigue properties of asphalt mixtures. In this paper, the SCB configuration was adopted for the determination of the dynamic modulus of asphalt mixtures. The main advantage of this configuration is that the influence of the Poisson ratio on the dynamic modulus calculation is practically non significant. A 2D-FEM model has been used for the development of an equation for the calculation of the dynamic modulus. An asphalt mixture was tested according to this proposed procedure for its validation and the obtained results are presented and discussed.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130872087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also being explored by various roadway agencies as part of performance related mix-design specifications.

As a result, several performance indicators have been proposed to describe the behavior of the mixtures tested. The objective of this study was to compare SCB-based indicators against the results obtained from a uniaxial tension-compression fatigue test using the viscoelastic continuum damage (VECD) approach. Three dense graded asphalt mixtures were tested at different temperatures under monotonic loading (AASHTO TP 105) and uniaxial tension-compression fatigue test. VECD-based predicted number of cycles to failure (Nf) were then compared to various SCB performance indicators.","PeriodicalId":234012,"journal":{"name":"Bituminous Mixtures and Pavements VII","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114960443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LTPP weather data over a year-long period, were analyzed for each location using the computer model TEMPS. It was concluded that the higher the coefficient of thermal conductivity, the heat capacity and the albedo of the pavement surface layer, the lower the average and maximum surface temperatures are during the summer months.
