This paper present the engineering properties of asphalt (AC 60/70) modified with different ratios of crumb rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 11% crumb rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 11% crumb rubber. For asphaltic concrete Marshall Stability increased and flow decreased with adding crumb rubber into asphalt. Comparing to ordinary asphaltic concrete (AC 60/70) the rutting resistance was increased 18% for crumb rubber modified asphalt respectively. Moreover the fatigue resistance of crumb rubber modified asphalt improved to be 1.59 times compared to AC 60/70.

This paper present the engineering properties of asphalt (AC 60/70) modified with different ratios of natural rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 6% natural rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 6% natural rubber. For asphaltic concrete Marshall Stability increased and flow decreased with adding natural rubber into asphalt. Comparing to ordinary asphaltic concrete (AC 60/70) the rutting resistance was increased 22% for natural rubber modified asphalt respectively. Moreover the fatigue resistance of natural rubber modified asphalt improved to be 2.06 times compared to AC 60/70.

The purposes of this research were : 1) to study the general information of the respondents and marketing mix factors 2) to study on purchasing behavior of fresh flowers from the invention business of consumers in Muang District Phuket Province 3) to study on relationship between general information of respondents and purchasing behavior of fresh flowers from consumer goods business in Muang District Phuket Province and 4) to study on the relationship between marketing mix factors and buying behavior of fresh flowers from the consumer invention business in Muang District Phuket Province. Samples were consumers living in Muang District Phuket and had purchased 400 fresh flowers from the invention business in Muang District Phuket Province. The instruments used is the statistical questionnaire used in data analysis include frequency value percentage value mean value standard deviation value and Pearson Chi-square. Statistical analysis using computer program. The results showed that : 1) most of the consumers are female between 20 and 29 years old. Have a bachelors degree. Most of occupation is private business such as trade or general contractor. Average monthly income is about 20001 - 30000 Baht. Most of consumers are living in Phuket. Consumers emphasize to the factor of marketing mix. Overall and individual aspects are at a high level 2) Consumers have a reason to buy fresh flowers for use in ceremonial or important events.
