| dc.description.abstract | The effects of pavement temperature on pavement modulus, particularly the asphalt layer modulus, are quite
apparent. In the analytical design method, the effects of pavement temperature can be taken into account in term of
design temperature factor, as that proposed by the Nottingham method. Alternatively as proposed by the Asphalt
Institute method, Miner’s theory can also be applied to calculate pavement thickness design directly that satisfies the
cumulative effects of pavement modulus variation. For this purpose, traffic loading spectrum across the pavement
temperature differences ought to be known. A research had been conducted to determine design temperature factor from
FWD deflection data measured four times in the morning, afternoon, evening and in the night within the same day.
Pavement modulus values were estimated from back calculation processes on the FWD deflection data. This paper
outlines the analytical design procedure based on the Nottingham method by using program PastDean employing the
calculated design temperature factor and the Miner’s theory, respectively. It was found that the remaining life of the
existing pavement structure being analyzed would be dictated by the fatigue cracking criterion, and the resulting design
temperature factor was 1.55. Further analysis is then presented to simulate hypothetically the design temperature factor
suitable for permanent deformation criterion. | en_US |
