This research aimed to study the use of coarse aggregate obtained from removing old recycled asphalt pavement (RAP) in the production of the porous concrete paving block. Crushing and size separation of the coarse aggregate by using standard sieve size by selected the gradation size of the coarse aggregate that passed to sieve size 1/2” and retained on sieve size 3/8” and other that passed to sieve size 3/8” and retained on sieve size No.4 by mixing ratio 50 : 50 of the mass as replaced natural coarse aggregate. Portland cement quantity about 18% and 20% by weight of the aggregate. The water to cement ratio was 0.30 and 0.35 respectively. Compressive strength flexural strength and water permeability were investigated. The results showed that the cement content and water to cement ratio was influenced the strength properties and water permeability rate of the porous concrete paving block. The porous concrete paving block mixed with higher cement content (20%) had the compressive strength at the age of 28 days increased by 16-24% when compared with lower cement content (18%). On the other hand the water permeability rate decreased by 5.1-8.1%.

This research aims To study and collect tie dye pattern. And to provide general knowledge of dyeing and textile patterns. There is no way to conduct the research. Related information in the form and method of making tie-dye process. On tie dye patterns by collecting information from documents and online media. And experimental techniques to tie fabric from the design on paper and bound pattern onto the fabric and dye. Then the pattern came prepared Knowledge Base tie dye pattern. In the form of books reports and disc CD / DVD. The results revealed that the tie-dye patterns. Appearing in the textile pattern consisting of natural geometry in depend. There are 2 types of tie-dye pattern patterns and continuous. Discontinuous pattern (pattern) Single-binding motifs. The tied pattern gnarled and Captured and tied fold stitching. Swiping stitched Other materials included in the bundle. Technical tortuous highway triangle triangle stacked square square. Type of pattern is composed of Independent and creative nature geometric patterns. stacked square with 4 slots a rectangle a triangle rocket a two-page independent. Which patterned tied each in a different pattern. Tie a knot button Before capturing Ties And other related materials patterns cannot continue as a single pattern. Tied and folding sewing swiping before the tied is a pattern that continued throughout the fabric. Which can be used for the creations a pattern on the cloth as well. This saves time in Ties pattern. Tied motifs in small quantities But when spread the cloth out of the piece. Pattern appears full fabric. Dyeing has the dye color 2-color with more than 2 colors dip-dyed by whole piece dip dyed the color level. In addition the pattern appears to products that include product type 1. home decoration 2. products clothing. The study pattern with tie-dyed textiles textile products and found that two types of usage patterns of all kinds. Depending on the designer And the purpose of the use of that product.
