New innovations in pavement materials and engineering: A review on pavement engineering research 2021

Sustainable and resilient pavement infrastructure is critical for current economic and environmental challenges. In the past 10 years, the pavement infrastructure strongly supports the rapid development of the global social economy. New theories, new methods, new technologies and new materials related to pavement engineering are emerging....

Fabrication of Nanoslits with <111> Etching TSWE Method

In this paper, we report a modified three step anisotropic wet etching (TSWE) method to fabricate solid-state silicon nanoslits. The slit-opening process is performed by &lt;111&gt; crystal plane etching. The etching rate of the &lt;111&gt; crystal plane is reasonably slow as it is only 1/45 of the &lt;100&gt; etching rate, thus allowing and...

Study on the aging resistance of polyurethane precursor modified bitumen and its mechanism

As an environmentally friendly alternative for the production of high-performance modified asphalt by chemical reactions, a liquid-state polyurethane-precursor-based reactive modifier (PRM) was developed and employed in the asphalt modification. In contrast to the traditional solid bitumen modifier, for example, rubber and thermoplastic...
