Compressive Strength Gain Behavior and Prediction of Cement-Stabilized Macadam at Low Temperature Curing

Abstract

For cement-based materials, the curing temperature determines the strength gain rate and the value of compressive strength. In this paper, the 5% cement-stabilized macadam mixture is used. Three indoor controlled temperature curing and one outdoor natural curing scenarios are designed and implemented to study the strength development scenario law of compressive strength, and they are standard temperature curing (20°C), constant low temperature curing (10°C), day interaction temperature curing (varying from 6°C to 16°C), and one outdoor natural temperature curing (in which the air temperature ranges from 4°C to 20°C). Finally, based on the maturity method, the maturity-strength estimation model is obtained by using and analyzing the data collected from the indoor tests. The model is proved with high accuracy based on the validated results obtained from the data of outdoor tests. This research provides technical support for the construction of cement-stabilized macadam in regions with low temperature, which is beneficial in the construction process and quality control.

Laboratory Evaluation of Strength Performance of Full-Depth Reclamation with Portland Cement Material

“…Kim et al [28] investigated the UCS development under curing temperatures of 5 • C, 20 • C, and 40 • C. The findings suggested slight differences during the initial process, while appearing nearly indistinctive with time. Xu et al [29] simulated local air temperature fluctuations and found that the UCS of 5% CSCS increases with prolonged curing time, with the rate of gain being lower at low temperatures compared to standard temperatures. Marzouk et al [30] conducted experiments over three months at five temperatures ranging from −10 • C to 20 • C, revealing a proportional relationship between UCS and temperature.…”

Influence of Asphalt Emulsion Inclusion on Fly Ash/Hydrated Lime Alkali-Activated Material

“…During the rainy season, the relatively high water can establish premature cracks in road pavement structures, allowing liquids to access and penetrate capillary and air voids, decreasing the durability of cement-based materials and AAMs [16][17][18]. Stabilizing materials with high moisture sensitivity decrease stiffness caused by excess moisture from an external environment [19,20], negatively impacting crucial pavement properties [21,22]. This problem results in redundant maintenance costs and cannot be resolved in many countries.…”
