Asphalt Mix

The main objective of this study was to investigate the effects of hot mix asphalt material properties on the performance of flexible pavements via mechanistic approach. 3D Move Analysis software was utilized to determine rutting and cracking distresses in an asphalt concrete (AC) layer. Fourteen different Superpave mixes were evaluated by utilizing results of the Dynamic Modulus (|E⁎|) Test and the Dynamic Shear Modulus (|G⁎|) Test. Results showed that with the increase of binder content, the tendency of rutting in AC layer increased. However, with the increase of binder content, the cracking of AC layer lessened. Furthermore, when different binder grades were evaluated, results showed that with the increase of the upper binder grade number, rutting decreased, and with the increase of the lower binder grade number, rutting increased. Furthermore, analysis showed that with the increase of the lower binder grade number, higher percent of bottom up cracks would result. As a result of the analysis, binder grade should not be solely considered for cracking in AC layer; binder content and aggregate structure play a big role. Finally, results illustrated that the mechanistic approach is a better tool to determine the performance of asphalt pavement than commonly used methods.

On the basis of test analysis, mix design of cement stabilized gravel powder, cement stabilized gravel powder mixed with 20% aggregates and cement stabilized gravel powder mixed with 40% aggregates were compared, their unconfined compressive strength were tested, and the mixed aggregates ratio and mix design were ultimately determined. The experimental results show that mixing a certain amount of aggregate can reduce cement dose and meet the design strength. Engineering project cost by mixing with a certain amount of aggregate was little higher than that of cement stabilized gravel powder. Comprehensively considering technical and economic factors, the recommended amount of aggregates mixed with 30% and cement dose of 2%.

Mineral Fillers

The rheology of asphaltic binders and their effects on asphalt concrete are discussed with the intention of improving the correlation between conventional mix design results and pavement performance. Test results show that mineral fillers increase the viscosity and pseudoplasticity of asphalts but do not always decrease the tan 8, except apparently at a lower frequency or at a higher temperature. Mineral fillers are also hard to mix homogeneously and quickly with asphalts. All these effects become more pronounced with a continuously increasing filler to asphalt (F/A) ratio, and uses are limited to a lower F/A range unless the processing temperature is adjusted properly. The abnormal drop in tan δ improves for some modified asphalts (e.g., air-blown or polymerized asphalt).

This study aims to determine the effect of product design and price on consumer interest in buying Jepara Teak furniture at the New Furniture Business Shop in Lubuk Alung. This type of research is associative quantitative research, the number of research samples were 100 people. Data was collected in the form of questionnaires and using analyzed SPSS software ver.21.0 for Windows. The conclusions from this study is the product design variable (X1) has a significant positive effect on purchase decision in Jati Jepara furniture at the New Furniture Business Shop in Lubuk Alung, as evidenced by t value > t table (10,400> 1,660) and a significant influence between price variables ( X2) purchase decision with t value> t table (2,015> 1,660). There is a positive and significant influence between product design (X1) price (X2), on purchase decision of Jati Jepara furniture consumers with an F-value 156,644> F- table (3,09) means that it affects together. The coefficient of determination (R²) results obtained a coefficient of 0.764 or 76.4%, while 23.6% is influenced by other variables.Keywords: Product design; prices; purchase decision.
