Photodegradation test of asphalt binder using pressed thin film samples
نویسندگان
چکیده
The photodegradation behavior of a straight asphalt was investigated using a new method “photodegradation test of asphalt binder using pressed thin film samples”. Although the photodegradation caused by outdoor exposure is limited to the near surface, the results confirmed that the degree of degradation during 1 to 2 months is more severe than that by the pressure aging vessel (PAV) test, which is designed to simulate the degradation that will occur in the asphalt pavement over 5 to 10 service years.

متن کاملModelling and Laboratory Studies on the Adhesion Fatigue Performance for Thin-Film Asphalt and Aggregate System
Adhesion between asphalt and aggregate plays an important role in the performance of asphalt mixtures. A low-frequency adhesion fatigue test was proposed in this paper to study the effect of environment on the asphalt-aggregate adhesion system. The stress-based fatigue model had been utilized to describe the fatigue behavior of thin-film asphalt and aggregate system. The factors influencing the...

The objective of this study is to evaluate the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica. In this study, the nanosilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binders. Superpave binder and mixture tests were utilized in this study to estimate the characteristics of the nano-modifed aspha...

Recycled asphalts were evaluated based on SHRP binder specification. DSR (Dynamic Shear Rheometer) and BBR (Bending Beam Rheometer) tests were carried out on samples of the recycled asphalts under three conditions: original binder, RTFOT (Rolling Thin Film Oven Test) residue and RTFOT+PAV (Pressurized Aging Vessel) residue. PG (Performance-Graded) classification was conducted. New straight asph...
