Special pavement test sections were selected to develop a distress prediction model on asphalt pavement of National Highway. Experimental design was conducted for the selection of LTPP sections on in-service pavement(new and overlaid pavement) using several variables affecting pavement performance. Preliminary sections that satisfied the design template were chosen from the national highway database, and final selection was fixed through field inspection. The number of monitoring section is 95 including 47 overlaid pavement. A pavement distress data such as crack and rutting were collected for two years. An interim pavement performance analysis was peformed to show feasibility of performance monitoring program. Data related pavement such as traffic, weather, material characteristic and crack etc. should be collected for next project years and distress prediction model will be developed through the statistical analysis.

Application of the foamed asphalt techniques in recycling the waste asphalt shows that large quantify of waste asphalt(60
70% of the total mix) can be used comparing with hot mix asphalt techniques and also is environmentally safe. However, the constant quality of the recycling foamed asphalt mixtures is not readily achieved and can not be applied to the heavy traffic road due to the characteristics of the conventional foamed asphalt mixtures. The semi-hot technique that the RAP and the aggregate is heated below
is adopted in this study and expected to solve the problems of conventional foamed asphalt mixtures. This study presents the viability of the semi-hot foamed asphalt mixtures when using the RAP. The semi-hot recycling foamed mixtures are tested and evaluated in the laboratory. The test results including coating rates, creep tests, resilient modulus tests, indirect tensile tests and the Marshall stability tests showed significant improvement.

This study was performed to estimate the high-speed direct tensile strength(DTS1), low-speed direct tensile strength(DTS2) , indirect tensile strength(ITS) resilient modulus(MR) and stiffness index(SI) of sand asphalt mixture based on the absolute viscosity, kinematic viscosity, penetration, softening point and PG grade of binder. DTS2 showed higher correlation with the physical properties than other properties of mixture, and the next was DTS1, ITS, SI and MR in order. Among binder properties, PG grade showed the highest relation with DTS2. Therefore. it was found that the high DTS mixture could be made when the binder with a high PG grade was used. However, since the individual physical property showed a relatively low correlation, various properties were used together in regression analysis. The estimation models of DTS and ITS were over 0.99, respectively. R2 of MR and SI estimation models were over 0.91 and 0.93, respectively. It was concluded that mechanical properties could be estimated with a high coefficient of determination from those physical properties.

This study is a fundamental research for recycling waste polyethylene film(WPF) in asphalt concrete for roadway pavement. The objective of this study is to develop technology of making waste polyethylene asphalt mixture and evaluate properties of the asphalt concrete containing WPF. Asphalt concrete for surface course of pavement was produced through an appropriate mix-design using dense-graded and gap-graded aggregates. Marshall mix design, indirect tensile strength test, wheel tracking test and tensile fatigue test were performed. Test result showed that some WPF asphalt mixtures had a high tensile property and good resistances against rutting and fatigue cracking, compared with normal asphalt mixture.

Guss asphalt used in pavement of a steel deck bridge may cause severe stress and displacement on the bridge as it is treated using very high temperatures ranging from 220oC to 260cC. Therefore, it is critical to estimate the thermal effect of Guss asphalt on the steel deck bridge before the width and pattern of the unit portion are decided in order to minimize impact. In this study, we have conducted a series of numerical analysis of the upper road of Youngjong Grand Bridge, verified the feasibility of numerical value analysis by comparing the results with the data measured, and studied the thermal effects of Guss asphalt on the steel deck bridge according to temperature changes.
