I would say I’m a hard working individual that has gained a lot of skills over the course of the five years I’ve been working in the PhD in asphalt technology.

The durability of asphalt pavements includes several aspects that can be related to the mechanical responses of materials, interactions between structural layers, and the influence of non-load related mechanisms such as oxidation, moisture effect, and severe weather conditions. The main purpose of this study was to characterise and understand the effects of ageing on the performance of Gap Graded Asphalt Mix (GGAM) at a range of moisture conditions. To assess the performance of mixture in terms of fatigue cracking and rutting potential, the experimental works were divided into two phases. In the first phase, the effects of CaCO3 with OPC or TPOFA as additives on the rheological properties of bitumen penetration grade 60/70 at high and intermediate temperatures was measured using the Brookfield Rotational Viscometer...

This paper focuses on a newly developed asphalt modifier named calcium carbonate (CaCO3) combined with Treated Palm Oil Fly Ash (TPOFA) to improve the properties of asphalt mastic. The rheological properties of mastic in terms of penetration, softening point, rotational viscosity and Superpave rutting factor using 60/70 asphalt binder blended with 5, 10, 15, 20 % of CaCO3+TPOFA were calculated to evaluate asphalt binder properties subjected to different aging conditions. The rotational viscometer (RV) was used to evaluate the properties of mastic at test temperatures from 120°C to 170°C. The dynamic shear rheometer (DSR) was used in temperature sweep test from 46°C to 82°C at 6°C increments at 10 rad/sec frequency to measure the G*, δ and Superpave rutting factor G*/sinδ. A one-way ANOVA statistical analysis was used to analyze the results .The test results showed that all asph...
