13. Influence evaluation of some factors in the mechanical properties of binder mixtures using design and analysis of asymmetric fractional factorial experiments technique / Avaliação da influência de alguns fatores nas propriedades mecânicas de misturas asfálticas densas, à luz da técnica de planejamento e análise de experimentos fatoriais fracionários assimétricos
This work deals with the influence of some factors in the mechanical behavior of asphalt mixtures stability and flexibility. Three types of binders were tested, conventional one, modified with 4,5% of SBS and modified with 20% of recycled tire rubber. Two aggregate gradations were tested, center of B and C gradations of DNER (1997). Four binder contents were

14. A Practical Approach to Evaluation of the Germicidal Efficiency of a General Purpose Military Disinfectant
The bactericidal activity of a general purpose disinfectant consisting of 25% sodium-o-phenylphenolate and 75% sodium-4- and 6-chloro-2-phenylphenolate was evaluated by a simulated in-use, surface-square dilution method. Common floor (asphalt, rubber, and unglazed tiles) and wall (stainless steel tile, ceramic tile, and painted wood) surfaces of various poro
