Asbuton is a natural asphalt material that has greater resilience and elasticity compared to extraction asphalt. When exposed the sun rain, asbuton strong solid nature, texture also elastic so it less likely crack. One of wastes continues be used in field road pavement plastic waste this research, which type polyethylene terephthalate (PET). A lot generated every year but little can used. This ...

Bivariate semi-logistic and Marshall-Olkin bivariate semi-logistic distributions are introduced. Some properties of these distributions are studied. First order autoregressive processes with bivariate semi-logistic and Marshall-Olkin bivariate semi-logistic distributions as marginals are introduced and studied.

cotton aphid, aphis frangulae gossypii glover, is a major pest of cucumber in iran. one of the important parasitoids playing role in population control of this pest in the fields and greenhouses is lysiphlebus fabarum marshall. in this study, we investigated sensitivity of different instars of cotton aphids and pupal stage of l. fabarum to field recommended and half-recommended concentration of...

The fatigue cracks are observed in asphalt surfaces much more than ruts. This paper deals with the influence of carbon nano-tube on the fatigue life of asphalt mixtures. These samples are made up of the slabs cut by the asphalt cutting saw. Fatigue beams contain 0, 0.3, 0.6, 0.9, 1.2, and 1.5 percent of Carbon Nano-tube. The fatigue experiment was conducted using a 4-point semi-sinusoidal loadi...

For several years, the bituminous laboratory of the Joint High­ way Research Project has been concerned with the testing of bitu­ minous-aggregate mixtures and with the development of knowledge that would lead to an understanding of the properties of bituminous mixtures as satisfactory paving materials. At the Thirty-Eighth Annual Road School, a paper entitled, “Role of the Laboratory in the De...

The objective of the present paper is to examine effect Recycled Asphalt Pavement (RAP) on marshall properties and indirect tensile strength HMA through experimental investigation. A mixture with 0% RAP was used as a control mix evaluate mixes 5%, 10%, 15% RAP. One type brought from Bab Al-moadam’s road in Baghdad for this purpose. testing program included Marshall Indirect Tensile Strength tes...

This study is focused on investigating the effectiveness of low heat accumulation asphalt mixture and its impact on the urban heat environment. Infrared radiation experiments showed that the temperature of the asphalt mixture decreased with the increase in far-infrared radiant material. The results also revealed that, compared to asphalt with 0% far-infrared radiant content, the asphalt materia...

The utilization of stone dust waste produced from PLTU Ketapang coal combustion process is still below optimal level. Produced reached ± 23,13 ton /day which consists 99,5% fly ash and 0,5% bottom ash. As a result, the writer gained an idea using as filler in bitumen mixture, especially Hot Rolled Sheet – BASE (HRS BASE). study was aimed to compare if used BASE) mix marshall test including void...
