State-of-the-Art Review on Sustainable Design and Construction of Quieter Pavements-Part 2: Factors Affecting Tire-Pavement Noise and Prediction Models
( MDPI AG , 2016 , Article Review)Traffic noise is a combination of noises produced from a number of sources. Of all the traffic noise sources, tire-pavement noise, which is emitted as a result of the interaction of rolling,slipping, or dragging tires and ... -
Diaphragm shear strength and stiffness of aluminum roof panel assemblies
( Elsevier Ltd , 2016 , Article)A diaphragm is an assembly of planar structural elements interconnected to each other to provide in-plane bracing system and transmit in-plane forces. The diaphragm geometry, supporting frame, type of the panel profiles, ... -
Reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers
( Elsevier Ltd , 2016 , Article)A trench can act as a barrier to ground vibration and is a potential mitigation measure for low frequency vibration induced by surface railways. However, to be effective at very low frequencies the depth required becomes ... -
Fatigue characterization of lightly cementitiously stabilized granular base materials using flexural testing
( American Society of Civil Engineers (ASCE) , 2016 , Article)The fatigue characteristics of a lightly stabilized granular material under traffic loading are important considerations for the design of a pavement containing such material. This paper examines the use of flexural testing ... -
Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
