The mere presence of artwork can remind drivers that these are people-centered spaces. But beyond aesthetic appeal, many asphalt art installations also include significant safety enhancements like curb extensions to shorten crossing distances and slow motor vehicles.
The logical place to experiment with asphalt art assisted traffic calming would be along University Ave and 13th St., where legions of UF students dodge cars every day. But state traffic bureaucrats tend to be notoriously suspicious of creative, low cost solutions to deadly problems and would likely veto the idea.
Reclaimed Asphalt Pavement (RAP) is a paving stripping material with Cold Milling Machine. The RAP accumulation in East Java Province is estimated 50,000 m3 per-year. The RAP usage can decrease RAP accumulation, natural material, damage rate by mining or excavation. RAP mixture produced an optimum performances (workability, stability). RAP improved volumetric and mechanical properties of mixture. On the other hand, the usage of RAP increased the brittleness of pavement. It is necessary to support in microstructural aspect so the addition of RAP can produce better performance. The objective of this study is to obtain physical and mechanical properties of asphalt concrete contain RAP. Method used literature study. The result showed the physical properties of aggregate and asphalt RAP according the specification standard exception on gradation, penetration and ductility. The Asphalt Concrete with RAP include in specification standard, exception was in the range of 3.78-4.63%, the optimum in VIM PRD. The asphalt content in RAP RAP of 20-30%. RAP can be used as AC-WC, AC-BC, AC-Base. The strength of RAP depends on the source of RAP. The usage of RAP requires new or other material so it become the environment friendly material

3. Lower environment impact
Recycled RAP can reduce the use of new pavement materials such as aggregate and bitumen, thereby reducing CO2 emissions from the production and transportation of those materials. For example, bitumen, derived from fossil resources, can be obtained by refining petroleum and emits a huge amount of CO2, a by-product of the refining process. Asphalt recycling can reduce the use of straight asphalt, of which CO2 emission intensity is high, therefore contribute to lowering CO2 emissions.
The technology adopts a method in which asphalt mixtures are paved to roads whose degraded or damaged pavement have been removed when roads are repaired. This reclaimed asphalt pavement, the RAP, will be recycled for producing recycled asphalt mixtures to be used again to pave roads. More specifically, recycled asphalt mixtures can be produced by heating recycled aggregate, produced through the cutting and grading of grains of RAP, and adjusting and mixing with new pavement materials (e.g. aggregate, bitumen, additives) to match the quality and performance standards of the road pavement.
The asphalt recycling technology is widely used in Japan, the U.S., and Europe. In Asia, Singapore has already implemented the Technology. Even in developing countries where asphalt recycling is not adopted, this is considered to be possible by establishing the design mix formula that meets local standards through laboratory-scale tests using local RAP, etc. By implementing asphalt recycling, road repair costs and CO2 emissions are expected to be reduced.
The asphalt recycling technology can reduce road repairing costs and CO2 emission compared to the conventional road repairing method (asphalt mixtures produced from new pavement materials + the overlay method), meeting local quality and performance requirements for asphalt paving. Costs are expected to be cut by 5% and the CO2 emission reduction to be approximately 7kg-CO2/ton-asphalt, although the effect varies depending on the RAP transportation distance.
The quality and performance standards for asphalt paving are specified by each country, therefore it is necessary to establish a design mix formula for producing recycled asphalt mixtures that meet local quality and performance standards. In Indonesia, with the help of local research institutions and road construction companies, we have established the design mix formula for asphalt mixtures for surface and base layers with the recycle rate of 40% and 50%. Below is an example of a performance test result of recycled asphalt mixtures for surface layers with the recycle rate of 40%.
A few years ago, we started working with Indonesian universities and research institutions to consider optimal design mix formula for producing recycled asphalt mixtures from local pavement materials in Indonesia (e.g. considering the composition rate of recycled RAP and new pavement materials). In addition, we paved recycled asphalt mixtures to public roads on trial to verify the performance and quality of them. As a result, we were able to establish the design mix formula for producing recycled asphalt mixtures for surface and base layers with the recycle rate (i.e. the rate of recycled materials) of 40% and 50%, and we are now in the process of commercializing the production technology we have established.
We constructed an asphalt recycling plant in Karawang, West Java Province, Indonesia and have a track record of selling recycled asphalt mixtures mainly for paving roads to private premises such as industrial parks.
Direct Ivestment
We established a joint venture company, named PT. Sugawara Kadi Indonesia, with a local road construction company in February 2017, and constructed an asphalt recycling plant in Karawang, West Java Province, operated jointly by KADII and SKI, in an effort to build a sustainable asphalt recycling system. We are considering constructing our second asphalt recycling plant in order to expand our asphalt recycling business further in Indonesia.
Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass.
What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect).
This is a conceptual question, I do not require a specific shading language or framework. In real life, I use Cg with Ogre for rendering experiments. If I supply two textures and two different texture coordinate sets for the tarmac entity, I can analyze the second texture coordinate set in the fragment shader and do some blending depending on the .y component of the uv pair, but that requires the artist to hand-craft every asphalt/tarmac runway in the scenario and it looked to me that this is probably the wrong way to tackle the issue.
The distribution characteristics of air voids in ultrathin asphalt friction course(UAFC) samples with different gradations and compaction methods were statistically analyzed using X-ray computed tomography (CT) and image analysis techniques. Based on the results, compared with the AC-5 sample, the OGFC-5 mixture has a higher air void ratio, a larger air void size and a greater number of air voids, with the distribution of internal air voids being more uniform and their shapes being more rounded. The two-parameter Weibull function was applied to fit the gradation of air voids. The fitting results is good, and the function parameters are sensitive to changes in both mineral gradation and compaction method. Moreover, two homogeneity indices were proposed to evaluate the compaction uniformity of UAFC samples. Compared with the Marshall method, the SGC method is more conducive to improve the compaction uniformity of UAFC samples. The compaction method significantly influences the air void distribution characteristics and compaction uniformity of AC-5 sample, but has a less significant impact on OGFC-5 sample. The experimental results in the study provides a solid foundation for further explorations on the internal structure and mixture design of UAFC.
