Development of Updated Specifications for Roadway Rehabilitation Techniques, May 2011 [PDF]
As our nation’s highway system continues to age, asphalt maintenance and rehabilitation techniques have become increasingly important. The deterioration of pavement over time is inevitable.

ABSTRACT Fatigue cracking is a major distress limiting asphalt pavement service life, and Paris law–based fracture mechanics offers a more mechanistic understanding than conventional fatigue testing. However, systematic characterization across diverse modifiers, dosages, notch depths, and temperatures remains limited.

Laboratory Performance Evaluation of CIR-Emulsion and it Comparison Against CIR-Form Test Result from Phase II, Final Report TR-578 Phase III, December 2009 [PDF]
Currently, no standard mix design procedure is available for CIR-emulsion in Iowa. The CIR-foam mix design process developed during the previous phase is applied for CIR-emulsion mixtures with varying emulsified asphalt contents.

Influence of the Skid Resistance of Ultrathin Wearing Course with Various Types of Asphalt Binders
Ultrathin wearing course (UTWC) has been widely applied in both asphalt pavements preventive maintenance and functional overlay. This study’s objective is to evaluate the influence of different modified asphalt binders with warm mix additives on the skid

Slow Infrastructural Violence: The Lived Experiences of Urban Essential Workers
Abstract We examine how non‐healthcare urban essential workers constitute a vital yet undervalued social infrastructure that enables everyday life in Switzerland. Drawing on 37 (walking) interviews, the study foregrounds the lived realities of those whose reproductive labour sustains the city while remaining largely invisible.

The Zr‐doped coralloid μSi encapsulated within an N‐coordinated dual‐carbon network is fabricated by an Al‐Si melt modification integrated with in‐situ interfacial strategy, consequently improving the ionic diffusion behaviors. Micro‐scale silicon (μSi) anodes are promising candidates for enhancing energy density of lithium‐ion batteries, yet their ...

Performance of sasobit modified asphalt binder in warm-mix asphalt technology [PDF]
Road maintenance is widely recognized, but not adequately maintained due to economic crisis of countries. Besides, increasing emission of greenhouse gases is an environmental issue, and it is a great concern to curb this problem from further harm to the ...

Material Characterization of Lignin‐Filled Polypropylene Composites
Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a
