POE-g-MAH flexible bridging enhances the compatibility of rubber plastic composite modified asphalt

Research Overview: Volume 547 of Construction and Building Materials published a study on the improvement of compatibility of rubber plastic composite modified asphalt. The authors were Mengkai Sun, Zhaoyi He, Guannan Li, Hongbo Liao, and Yifan Cheng. The paper was published on November 14, 2026. The research focuses on the compatibility issues between different components in rubber and plastic composite modified asphalt systems, and proposes a solution approach using POE-g-MAH as a flexible bridging component.

Core facts and technical route

Rubber and plastic composite modified asphalt has potential applications in the fields of road and building materials, but the interface compatibility between the rubber phase, plastic phase, and asphalt matrix directly affects the modification effect and material stability.

. This study focuses on the flexible bridging effect of POE-g-MAH, and explores the interfacial behavior of this component in the composite modified asphalt system through compatibility enhancement and mechanism analysis. From the title and source information, the focus of the research is on two aspects: “compatibility enhancement” and “mechanism”: on the one hand, evaluating the improvement effect of POE-g-MAH on the compatibility of rubber plastic composite modified asphalt, and on the other hand, explaining its bridging effect from a mechanism perspective. The source did not provide specific dosage, performance test values, and microscopic characterization details. The relevant quantitative conclusions should be based on the full text of the paper.

Significance for the polymer additive industry

Asphalt modification is an important direction for asphalt and concrete modification in building and home decoration materials.

. The rubber plastic composite modification system introduces both rubber and plastic components, making the interface problem more complex. Therefore, improving compatibility has become a key step in formula design. POE-g-MAH, as a maleic anhydride grafted polyolefin additive, provides a flexible bridging approach that can be used as a reference for interface control of modified asphalt. For polymer additive companies, this research direction suggests that in the application of building materials, the value of additives is not only reflected in their single function, but also in the interfacial synergy of multiphase systems. The similar approach is similar to the method of using antioxidants and light stabilizers to ensure weather stability in PVC profile formulations – both improve the performance stability of materials under long-term use conditions through additive design. The synergy between compatibility and weather stability in asphalt modification may also become a focus of attention in subsequent formulation development and testing evaluation.

Uncertainties to be concerned

The source only provides the paper title, journal issue, and author information, and does not disclose the specific dosage, preparation process, compatibility evaluation indicators, and mechanism characterization methods of POE-g-MAH.

. The applicability of the research conclusion, its compatibility with existing modified asphalt processes, and its weather resistance and aging performance under actual engineering conditions all need to be further verified based on the full text of the paper.
