This paper carries out a systematic study on the influence of various factors on the crack resistance of asphalt mixtures using a semicircular bending test. The specific results are as follows: At low temperatures (0°C and below), cracks develop rapidly after the asphalt mixture reaches its peak force, and the asphalt mixture shows brittle damage. Basalt asphalt mixtures have significantly better LTC resistance than limestone. The smaller the maximum nominal size of the aggregate, the better the LTC resistance of the asphalt mixture. The LTC resistance of SBS-modified asphalt mixtures is significantly better than that of Pen.70 virgin asphalt mixtures. The cracking resistance of asphalt mixtures increases after water saturation under non-low-temperature conditions, while water saturation significantly reduces the LTC resistance of asphalt mixtures. The aging can significantly reduce the LTC resistance of asphalt mixtures. Based on the random forest method, it is concluded that temperature, asphalt binder type, and aging are the key factors affecting LTC, the normalized importance score is 39.59 %, 21.91 %, and 11.8 %, respectively. Developing modified asphalt binders with low-temperature sensitivity, aging resistance, high toughness, and high adhesion is the key technology to improve the LTC resistance of asphalt mixture from the material itself.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"485 ","pages":"Article 141937"},"PeriodicalIF":7.4,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144139726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the P-removal rate increases with the increase of flocculant polyaluminum sulfate (PAS) content. Chemical adsorption is the main P-removal mechanism according to adsorption kinetics. The addition of PAS is beneficial to increase the average pore size and total porosity of FFA, especially for the volume proportions of >1.6 mm pores, which is attributed to the high hydrolysis heat of PAS promoting H<sub>2</sub>O<sub>2</sub> foaming.

Firstly, the atmospheric components aging test was designed to obtain the aged asphalt binder samples under the conditions of pure nitrogen, oxygen, carbon dioxide and noble gases (helium), and to compare their macro morphological characteristics. Subsequently, the micro effects of different atmospheric components on asphalt binder were analyzed by asphalt SEM testing, and the evolution mechanism of its micro-morphology was revealed.

Results show that different atmospheric components have different effects on the aging behavior of asphalt binders, in which the contribution of oxygen is more obvious, while helium plays a delayed effect.

This study comprehensively investigates the effect of different contents of biochar referred to as micronized vegetable carbon (MVC) as cement substitute, water and SP, on the hydration, setting, workability, microstructure and strengths of mortars. Isothermal calorimetry revealed that, up to 10 wt% MVC, increasing both MVC and water contents improves cement hydration due to the nucleation effect, that counterbalances the dilution effect. A Vicat test-based specific method showed a slight acceleration of setting with increasing MVC content (reduction in setting time of 13 and 41 min for 5 and 10 wt% MVC) due to its water absorption. Mini-slump tests with and without SP showed that MVC has a direct impact on rheology but not on the fluidizing effect of SP. A stable microstructure is created when the water to cement ratio remains constant while the cement content decreases, resulting in higher-than-expected strengths (6 % increase at 28 days for 10 wt% MVC).
