In order to investigate the effect of polyurethane (PU) modifier on the anti-UV aging ability of
asphalt, in this study, the base asphalt and PU modified asphalts were subjected to short …

In order to investigate the effect of nano polymer materials on the UV aged performance of
asphalt binder, a nano PA modifying agent was selected to prepare modified asphalt. Under …

To solve the problems such as poor storage stability, easy segregation and aging for
polymer modified asphalt, the polyurethane (PU) was used to chemically modify the asphalt …

In this reported work, thermoplastic polyurethane (TPU) was used as a reactive polymer
modifying agent to prepare a modified-asphalt, using a high-speed shearing method …

The ultraviolet (UV) aging of asphalt is an important factor affecting the long-term
performance of asphalt pavement, especially in high altitude cold regions. The current …

Waste engine oil (WEO) and waste polyethylene (WPE) are two common wastes, which are
easy to pollute the environment. As the primary material in road construction, natural asphalt …

To analyze the effect of polyol on polyurethane (PU)-modified asphalt, three different soft
segments of polyurethane were synthesized, and we utilized the reaction of MDI …

To study the rheological and aging properties of vegetable oil–based polyurethane (V-PU)
modified asphalt, V-PU terminated with an–NCO group was synthesized from renewable …

Polyurethane (PU), with excellent physical and chemical properties and high designability,
is one of the ideal materials for asphalt modification in the future. In this paper, based on the …

The high cost and high dosage of polyurethane (PU) used in asphalt modification limit its
application in asphalt pavement construction. To address these problems, two novel PUs …
