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

This study addresses the high mixing temperatures, high viscosity, and low-temperature cracking of rubber-modified asphalt (AR) and evaluates the modification performance of a domestically developed USP warm-mix technology. USPA-R and USPA-C2 are used to prepare warm-mix rubberized asphalt, and corresponding mixtures are designed with AC-13 and SMA-13 gradations. Penetration, softening point, ductility, viscosity, BBR, DDT, fluorescence analysis, and three-point bending tests are conducted in accordance with relevant standards, and ABAQUS simulations are integrated to elucidate mechanisms and quantify performance responses. The results show that both warm-mix additives improve the conventional properties and low-temperature deformation resistance of asphalt concrete (AC), with USPA-C2 exhibiting superior performance. In three-point bending, AC-13 generally outperforms SMA-13; relative to AC-R, USPA-C2 increases the maximum flexural strain by approximately 252 µε, whereas USPA-R yields an increase of about 142 µε. When fibers are incorporated, crack resistance is further enhanced, with basalt fiber providing the greatest benefit (≈ 16.8% improvement at - 10 °C). Mechanistically, the warm-mix agents are understood to promote binder mobility and energy dissipation by modulating asphalt-fraction distribution and intermolecular interactions. Overall, low-temperature crack resistance is substantially increased while required construction temperatures are reduced, thereby extending service life, decreasing curing demands, and delivering energy-saving and emission-reduction benefits.
