1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Microorganisms are increasingly recognized as biological factors that may influence asphalt materials performance and pavement service behavior. This review integrates petroleum biodegradation mechanisms, petroleum asphalt composition, and direct asphalt evidence to examine microbial effects in asphalt systems. The results show that microbial effects mainly depend on preferential fraction transformation and environmental regulation. Light and bioavailable fractions, especially saturates and some aromatic compounds, are more easily utilized, whereas resins and asphaltenes are more resistant but may still undergo limited transformation. Environmental factors regulate microbial activity, substrate availability, and mass transfer. Direct studies show microbial action may consume light fractions, enrich heavy fractions, change surface and molecular features, weaken adhesion, increase viscosity or stiffness, and reduce water stability, thereby promoting asphalt deterioration during service. Controlled microbial processes may support asphalt modification, recycling, regeneration, and sustainable maintenance. Future studies should clarify asphalt-specific microbial mechanisms and assess their sustainable potential in asphalt recycling and maintenance.
