In order to prepare a kind of high‐performance asphalt pavement pit repair material and extend the service life road, this paper starts from microscopic view raw materials, uses infrared spectrum, four component analysis method, lying drop column wick technology principle, etc. select materials determine initial amount cold patching mixture, optimizes formula through orthogonal test design adhesion, cohesion, stage strength, later residual stability, other performance indexes, determines...
Cold recycling mixtures with foamed asphalt is one of the green and environmental-friendly construction technology in pavement rehabilitation. Most materials could be utilized this kind technology. Water, cement, aggregate will added into at room temperature during production cold mixtures. However, adding water may have a negative effect on adhesion among asphalt, new materials. Especially regions, existence excessive introduce freeze-thaw durability issues winter-spring cycle. Therefore,...
Warm mix asphalt mixtures have the advantages of energy saving, emission reduction and good road performance. Zeolite mixtures, as a warm mixing technology, been applied in world. To understand mechanism zeolite mixture, mesoscale structure is studied. Micro computed tomography (CT) utilized to obtain internal image zeolite-modified mixture. The quantity volume voids are used void distribution evaluation indexes. results indicate that with respect asphalt, increase temperature, there an...
In order to explore the construction performance of zeolite asphalt mixture, microproperties and macroproperties mixture were studied. The structure composition, surface properties, pore characteristics analyzed by infrared spectroscopy pressure pump method. structure, thermal stability differential scanning calorimetry thermogravimetry, mechanism moisture absorption loss water was explored, properties effect type amount on viscosity studied test. According mixing current compaction void...
With the increasing awareness of warm asphalt technology, it is imperative to study properties binders containing additives. However, there are few studies on meso-scale binders. This paper aims meso-structure zeolite-asphalt system. The mesoscopic features studied with scanning electron microscope, and pores’ characteristics zeolite analyzed mercury intrusion porosimetry test. stereo microscope X-ray CT technology employed conduct two-dimensional qualitative analysis three-dimensional...
