چکیده
In order to study the micro-aging mechanism of lignin-modified asphalt, different asphalt samples were prepared with lignin content 0% and 12% by mass. The conventional index test high-temperature dynamic shear rheological used analyze samples. change law performance modified thermal oxygen aging time. results show that adding appropriate amount each will increase penetration ductility base reduce softening point, significantly improve stability; comparative analysis before after DSR aging, complex modulus G * increases decrease phase angle δ indicates can properties asphalt.

15 صفحه اولResearch on Design Technology of TLA Modified Asphalt Mixture
Marshall Test design methods are used to design TLA modified asphalt mixture and base asphalt mixture respectively, and their pavement performance is tested. The results showed that there is a transforming coefficient of 1.15 between OAC of 40% TLA modified asphalt mixture and that of base asphalt mixture, and ultimate gradation of the TLA modified asphalt mixture is finer than previous gradati...
متن کاملShort-Term Aging Effect on Properties of Sustainable Pavement Asphalts Modified by Waste Rubber and Diatomite
Waste utilization has gained more and more interest. In this study, crumb rubber and diatomite were used to modify asphalt binder and the short-term aging effects on the properties of modified asphalts were evaluated. Three kinds of modified asphalt were prepared; they are diatomite modified asphalt (DA), crumb rubber modified asphalt (RA), and diatomite and crumb rubber compound modified aspha...

OBJECTIVE: Obesity is a worldwide health problem, with increasing prevalence associated with an increased risk of chronic diseases. Decrease in energy intake has been shown to lower the risk of coronary artery disease (CAD) in obese. The common form of dietary restriction is daily calorie restriction (CR). Another form is alternate-day fasting (ADF). The ability of modified ADF to facilitate we...
متن کاملPolymer Modified Asphalt Emulsion
In road paving industry, asphalt emulsion is used for cold mix application such as chip seal, slurry seal, microsurfacing, cold recycled mixture and etc. Asphalt emulsion has several advantages compared to normal asphalt such as eco-friendly, easy to handle at ambient temperature and energy saving material because it does not need any heating process in its application. The history of asphalt e...
