Eleventh International Conference on the Bearing Capacity of Roads, Railways and Airfields: Volume 1

Description

Innovations in Road, Railway and Airfield Bearing Capacity – Volume 1 comprises the first part of contributions to the 11th International Conference on Bearing Capacity of Roads, Railways and Airfields (2022). In anticipation of the event, it unveils state-of-the-art information and research on the latest policies, traffic loading measurements, in-situ measurements and condition surveys, functional testing, deflection measurement evaluation, structural performance prediction for pavements and tracks, new construction and rehabilitation design systems, frost affected areas, drainage and environmental effects, reinforcement, traditional and recycled materials, full scale testing and on case histories of road, railways and airfields. This edited work is intended for a global audience of road, railway and airfield engineers, researchers and consultants, as well as building and maintenance companies looking to further upgrade their practices in the field. cover Half Title Title Page Copyright page Table of contents Preface Organizing committee Asphalt materials Comparing asphalt modified with recycled plastic polymers to conventional polymer modified asphalt Possibilities of surface protection on road and airport pavements Developing high performance asphalt mixtures with considerable amounts of recycled asphalt with a new chemical bitumen additive Study on low-temperature crack resistance of zirconium tungstate modified asphalt mastic and asphalt mixtures Evaluation air void content of drilled porous asphalt mixture cores using non-destructive X-ray computed tomography Experimental investigation on rheological property of bitumen influenced by preheating process Skid resistance properties against RAP content change in surface asphalt mixture Generation and propagation of reflective cracking and thermal cracking of asphalt pavement in cold regions of China Validation of national empirical pavement design approaches for cold recycled asphalt bases Ethylene-Octene-Copolymer as an alternative to Styrene-Butadiene-Styrene bitumen modifier Exploring correlations between the compressive modulus and the flexural modulus of asphalt concrete mixtures Viscoelastic characterization and comparison of Norwegian asphalt mixtures using dynamic modulus and IDT tests Granular materials Evaluating the effect of mineralogy and mechanical stability of recycled excavation materials by Los Angeles and micro-Deval tes Freeze-thaw performance of granular roads stabilized with optimized gradation and clay slurry Stabilization and geogrids Evaluating the cost effectiveness of using various types of stabilized base layers in flexible pavements Measurement of modulus of subgrade reaction for geogrid stabilized roadways Waste paper ash as an alternative binder to improve the bearing capacity of road subgrades Experiences with the use of stabilisation geogrids in demonstrating an improvement in bearing capacity of recycled materials Airport design Introducing dynamic asphalt modulus to the design of flexible aircraft pavement structures Practical implications for the implementation of the new international airport pavement strength rating system Analyzing the bearing capacity of materials used in arresting systems as a suitable risk mitigation strategy for runway excursio Road design Impact of introducing longer and heavier vehicles on the bearing capacity of pavement subgrades Post-Modern Pavement: Theory, concept, performance and challenges Concrete pavements Crack behavior of continuously Reinforced Concrete Pavements (CRCP) in Germany Modelling A model for the permanent deformation behavior of the unbound layers of pavements Development of simplified models to assess pavement structural condition on network level Predicting asphalt pavement temperatures as an input for a mechanistic pavement design in Central-European climate Stress random distributions on railway subgrade surface under train loads considering irregular shapes of ballast Modelling and predicting asphalt deflection values with artificial neural networks Analysis and modelling of the main causes of unsatisfactory quality of transportation infrastructures Influence of acceleration and deceleration of Super Heavy Loads (SHLs) on the service life of pavement structures Analytic analysis of a grid-reinforced asphalt concrete overlay Calibration of fatigue performance model for cement stabilized flexible pavements Case study Stone mastic asphalt as an ungrooved runway surface: Case study on Emerald airport Field investigation of the deterioration of flexible polymer modified pavements: A case study in northern New England NDT and APT Traffic speed deflectometer measurements at the Aurora instrumented road test site Unbound pavement materials’ response to varying groundwater table analysed by falling weight deflectometer FWD quality assurance in Germany Identifying weak joints in jointed concrete pavements from TSD measurements by basis pursuit Assessing the usefulness of the outer-area method in quantifying the structural capacity of full-scale composite pavement sectio Prediction of subgrade soil density using dielectric constant of soils Traffic speed deflectometer measurements at Copenhagen airport Field performance assessment versus asphalt pavement design considerations Using non-destructive test to validate and calibrate smart sensors for urban pavement monitoring Author Index Author Index
