Study on Crystallization Mechanism of Asphalt Mixture in Bridge Deck Pavement
نویسندگان
چکیده
This study focuses on unknown crystal precipitates from an asphalt mixture used in bridge deck pavement layers. X-ray fluorescence spectroscopy was to analyze the composition and source of crystals pavement, infiltration tests, porosity splitting tests multi-wheel rutting were carried out determine precipitation area non-precipitation explain influence road performance pavement. A nuclear-free densitometer 3D ground-penetrating radar (3D GPR) detect thickness uniformity whole section formation mechanism crystals. The results showed that main components water molecules, while rest mainly came machine-made sand, there no significant difference areas where precipitated. caused by rainwater penetrating into through coarse segregation collecting depression lower bearing layer. Under high temperature, solution precipitated formed

Study on Performance of Epoxy Asphalt Concrete Applied in the Deck Pavement of Pingsheng Steel Bridge
As a fair deck pavement material of its kind used in steel bridge, the epoxy asphalt concrete is considered much more superior to ordinary asphalt concrete in terms of road performance, while still greatly subject to the level of design and construction. Starting from a practical case of the epoxy asphalt concrete that has been applied in the deck pavement of Pingsheng Steel Bridge, this paper ...
متن کاملEffects of Warm-mix Asphalt Additives on Asphalt Mixture Characteristics and Pavement Performance
The primary objective of this research is to evaluate the feasibility of several WMA mixtures as potential asphalt paving mixtures for Nebraska pavements. To that end, three well-known WMA additives (i.e., Sasobit, Evotherm, and Advera synthetic zeolite) were evaluated. For a more realistic evaluation of the WMA approaches, trial pavement sections of the WMA mixtures and their HMA counterparts ...
