【 摘 要 】

Quality control and assurance are essential in pavement construction. In general, the properties of bitumen change as it ages in bulk storage, transport, and storage on site. The minimization of bituminous hardening during storing, transportation and mixing depends on careful control of binder temperature. Hence therefore, bitumen should always be stored and handled at the lowest temperature possible, consistent with efficient use. The objective of the work is to monitor the quality of bitumen samples collected from mixing plant and quarry. Results showed that, samples modified bitumen which collected from quarry showed some adverse effects on rheological properties and physical properties after subjecting to high temperature storage within a period of time. The dynamic stiffness, elastic properties and other common binder properties were deteriorated too. The chemical changes that occurred during storage were analysed using Fourier transform infra-red spectroscopy (FTIR). Thus studies developed an understanding of bitumen ageing in storage.
