| dc.description | Using mineral additions to improve asphalt concrete properties has been widely adopted as an effective approach. Among the mineral fillers used, hydrated lime [Ca (OH)2] has been shown to offer outstanding benefits in terms of both effectiveness and cost. Earlier research at the University of Salford has revealed that replacing limestone dust, a conventional mineral filler, with hydrated lime at 2.5% of total aggregate weight optimised mechanical properties at three different temperatures. In addition to this, it is also widely reported that using hydrated lime as a partial mineral filler helps in improvement of asphalt concrete’s capacity to resist the three typical distresses of constructed pavements. | |
| dc.description.abstract | The flexible pavement suffers primarily from three types of distress: fatigue cracking, thermal cracking, and permanent deformation. Thermal effects from climate are a significant in distress and early aging of pavements, and particularly in extreme weather contexts. To facilitate durable pavement design and construction, a deep understanding of the temperature profile within pavement structures becomes essential in order to assess internal stress and strain conditions together with mechanical loading from traffic. Two major fields of research are important in evaluating thermal effects on pavement structures. One relates to asphalt concrete material properties, thermal and mechanical, and their interactions. The other concerns service conditions like weather and climatic variation, which affect energy exchange at the surface. Obtaining complete and accurate material property values and characteristics for variation under coupled thermo-mechanical loading is a primary task in asphalt materials research. | |
