  • The combined waterproofing technique, which forms the waterproofing layer of two or more substances, is characterized by forming a waterproof layer, which is characterized by the formation of waterproof layers and the thickness of the waterproofing layer is inherently formed. In this study, it is intended to verify the integrity of the material through the manufacture of materials for special purpose waterproofing methods, primarily for the manufacture of composite waterproofing materials and composite waterproofing methods using cement materials and materials.

  • The pressure-sensitive adhesive(PSA) tapes are widely used as floor-sealing material in Korean constructive industry. However, the general PSA tapes can not seal the apertures completely. This is one of main reasons to cause imperfect finishing. In order to solve the problems, the asphalts were modified by FKM powder and SBS in this study. The physical properties of modified asphalts were examined by measuring the softening point, viscosity, tensile strength and adhesion strength of FKM and SBS modified asphalt. The softening point of SBS modified asphalt was increased greatly due to the formation of network structure in asphalt. Also, the change of adhesion strength of SBS modified asphalt with temperature was not so great comparing to those of pure asphalt and FKM modified asphalt. The best results of pressure-sensitive adhesion could be obtained by the SBS(linear) modified asphalt containing 6 wt.% of linear type SBS.

  • In this paper, overseas criteria and research results were reviewed to develop a rational criterion proper to domestic airport runways on measurement of friction coefficient and removal of rubber deposit. The friction coefficients of the runways of the Incheon International Airport were measured by the ASFT(Airport Surface Friction Tester) from August 2007 to July 2009 and the data at intensively landed points were analyzed. Variation of the friction coefficient due to accumulation and removal of tire rubber was analyzed and seasonal influence on the variation were investigated by pavement types. The friction coefficient steadily decreased over a long term despite periodical removal of the rubber deposits. The variation of the friction coefficient in summer was larger than other seasons and asphalt pavement was more sensitive to the seasonal influence than concrete pavement. The friction coefficient of the asphalt pavement with macro texture was even larger than that of early age concrete pavement with micro texture. The variation of the friction coefficient of the asphalt pavement due to the deposit and removal of the tire rubber was also larger than that of the concrete pavement.

  • Generally, asphalt binder modifier increases the viscosity at high temperature as well as at mixing and paving temperature, so that higher temperature is required to produce the hot-mix asphalt. Otherwise, wax is able to improve workability by means of decreasing the viscosity of asphalt binder. In this study, the effect of PE wax used to modify the asphalt binder was evaluated in laboratory. The properties of PE wax modified binder were compared with those of SBS and Crumb Rubber Modified binders. The results showed that wax type I has an effect on strengthening rut resistance as well as improving workability. However, wax type I weaken crack resistance due to making binder harder at intermediate temperature. The results also showed that wax type II has an effect on improving workability and on strengthening crack resistance due to making binder softer.

  • Rubber related geosynthetics(GS) as reinforcement and water barrier materials were manufactured by thermal bonding method and examined the their performance for applications to civil and environmental engineering fields. The spunbonded polyester nonwoven, fiber glass mat and fabric type geogrid of a high tenacity polyester filament were used as matrix and polyester film, elastomeric bitumen with SBS polymer and asphalt were used as reinforcements to manufacture the rubber related geosynthetics. A fiber glass mat and geogrid matrix GS showed more excellent mechanical properties and nonwoven and elastomeric bitumen matrix showed the more excellent permittivity. Softening points of rubber and asphalt mixture showed no difference and dimensional stability at high temperature, $120^{\circ}C$, represented no significant shrinkage. Resistance to ultraviolet of rubber related geosynthetics showed no visible alteration.

  • This work is about the development or asphalt sealant using the waste edible oil. Asphalt sealant has been used for crack filler and bridge deck joint sealer Several plasticizers such as aromatic or paraffin process oils, DOP, Bunker C fuel oil, and waste edible oil were compounded with the basic components such as asphalt(AP-5), a thermoplastic elastomer(SBS triblock copolymer), a tackifying agent(petroleum resin), and stabilizers. Penetration, softening point, ductility, and elongation by tensile adhesion of those asphalt sealant compounds were measured. Their properties were changed largely depending on both the type and content of plasticizers. Waste edible oil and DOP were the best plasticizers for the low temperature tensile adhesion characteristics. Penetration and elongation by tensile adhesion of asphalt sealant compounds increased with the increase of waste edible oil content and decreased with the increase of talc content. The manufacture of asphalt sealant with low penetration and excellent low temperature tensile adhesion was possible by the recipe optimization.
