چکیده
Research on waste tire pyrolysis carbon black (PCB) in bitumen mixtures indicates that it has excellent high-temperature rutting resistance; however, the degradation of low-temperature crack resistance and water stability PCB-modified asphalt limits its wide application. Therefore, hot-mix (HMA) were enhanced by addition chicken feather (WCF). Based response surface methodology (RSM), a variance analysis (ANOVA) P-value test model coefficient carried out, performance prediction models percentage air voids (VV) bituminous mixtures, 30-min Marshall (MS), 48-h MS obtained. The interaction effects different independent variables analyzed. In addition, optimal solutions multiresponse obtained optimizer 0.20% PCB content, 0.36% WCF shearing time 5.78 min for WCF, 6.66% asphalt–aggregate ratio. corresponding index values 4.00% VV, 12.80 kN MS, 12.65 MS. road results demonstrated incorporating improved resistance, asphalt. This study provides precise adding to HMA.

Evaluation of Fatigue Properties of Asphalt Mixtures Containing Reclaimed Asphalt using Response Surface Method
This paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. Central composite method was used to design of experiments based on response surface method (RSM). Binder type (Pen 60/70 and Pen 85/100), reclaimed asphalt pavement (RAP) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...
Study of Compaction in Hot-Mix Asphalt Using Computer Simulations
During the process of compaction in Hot-Mix Asphalt (HMA) mixtures, the distance between aggregate particles decreases as they come together and eliminate air-voids. By measuring the inter-particle distances in a cut-section of a HMA sample the degree of compaction can be estimated. For this, a calibration curve is generated by computer simulation technique when the gradation and asphalt conten...
