The building material industry has the largest share in global environmental emissions. This research investigates the environmental impact of polymeric concrete compared to conventional concrete in the construction of a new clinic at Assiut University Hospital in Egypt. A life cycle assessment (LCA) was conducted from raw material extraction to production stage (cradle to gate stage) using SimaPro V9.5 software. All environmental impact has been investigated using the IMPACT2002+ method using the midpoint and endpoint results. The LCA results showed that polymeric concrete had a lower environmental impact than conventional concrete regarding global warming, acidification, and eutrophication potential. In terms of the single score outcomes, climate change had a significant impact on both ordinary and polymer concrete, with the former scoring 0.90 mPt and the latter recording a much lower 0.14 mPt , indicating a 75% reduction. Furthermore, when considering the weighting results (midpoint result), it was found that specific environmental impacts, such as global warming, respiratory inorganic, and non-renewable energy impacts, had a more significant effect overall. Specifically, the global warming potential was found to be 8.95 Kg CO 2 eq. and 1.38 Kg CO 2 eq. for polymer and ordinary concrete, respectively. Lastly, the endpoint result showed that human health was impacted the most, with a total reduction of 84.24%. The DALY recorded for ordinary concrete was 3.69E-06, whereas, for polymer concrete, it was 5.8E-07. The findings of this study suggest that polymeric concrete can be a more sustainable alternative to conventional concrete for specific applications. One of the main difficulties faced in applying polymer concrete in the construction industry is its higher cost compared to conventional concrete. The production process of polymer concrete requires specialized equipment and expertise, which can increase the overall cost of the material. Additionally, the use of polymer concrete may require changes in construction techniques and design specifications, which can be challenging for contractors and engineers who are used

Pavement performance prediction is widely considered as a significant element of road infrastructure asset-management systems or Pavement Management Systems (PMS) by pavement researchers and practitioners. Predicting pavement performance significantly reduces the huge costs of constructing roads, especially in the case of countries that made incredible investments in road construction. This study mainly focuses on the implementation of the mechanistic-empirical (M-E) analysis method using the AASHTOWare Pavement ME Design (AASHTOWare PMED) software for flexible pavement distress prediction-models generation. To achieve that four steps were followed. First, the most accurate assessment that shows the combined impact of the most important parameters that affect flexible pavement performance was used to perform the AASHTOWare runs. In which, 378 design combinations of (3 traffic speed levels × 3 traffic load levels ×3 climatic zones ×7 Surface HMA mixes widely used in Egypt) at two input levels of the AASHTOWare PMED hierarchy (levels 1 &2) that typically are required for binders and hot-mix-asphalt (HMA) were used. Second, a sensitivity analysis to study the combined effect and impact of the investigated parameters on AASHTOWare PMED-predicted performance (cracking, rutting, and roughness) was conducted at the two input levels. Third, a Multiple Linear Regression (MLR) was implemented as a modeling approach to develop five performance prediction models for flexible pavements based on the AASHTOWare PMED software results. The proposed MLR models predicted each distress as a function of climatic factors, the surface HMA properties, different regions' speed levels, and traffic volume levels. Finally, a validation process of the proposed MLR prediction models was conducted. Results indicated that the proposed models yield an overall good prediction, asserting the robustness of the proposed process. Proposed MLR prediction models can be perceived as a function of Average Annual Daily Truck Traffic, Traffic speed, mean annual air temperature, and the percentage of air voids. This study provides a procedure to develop the performance prediction models of flexible pavements based on the AASHTOWare PMED approach and in accordance with different regions’ input levels.
路面性能预测被路面研究人员和从业人员广泛认为是道路基础设施资产管理系统或路面管理系统(PMS)的重要组成部分。预测路面性能可以显著降低道路建设的巨大成本，特别是在道路建设投资惊人的国家。本研究主要利用AASHTOWare Pavement ME Design (AASHTOWare PMED)软件实现力学-经验(M-E)分析方法，生成柔性路面破损预测模型。为实现这一目标，采取了四个步骤。首先，对影响柔性路面性能的最重要参数的综合影响进行了最准确的评估，并用于AASHTOWare下入。其中，378个设计组合(3个交通速度级别×3个交通负荷级别×3气候带×7埃及广泛使用的地面HMA混合物)在AASHTOWare PMED层次的两个输入级别(1级和2级)中使用，通常需要粘合剂和热混合沥青(HMA)。其次，进行敏感性分析，研究两种输入水平下所研究参数对AASHTOWare pmed预测性能(裂纹、车辙和粗糙度)的综合影响和影响。第三，基于AASHTOWare PMED软件的结果，采用多元线性回归(MLR)作为建模方法，建立了5个柔性路面性能预测模型。提出的MLR模型预测了气候因素、地表HMA属性、不同区域的速度水平和交通量水平的函数。最后，对所提出的MLR预测模型进行了验证。结果表明，所提出的模型产生了一个整体良好的预测，断言所提出的过程的鲁棒性。提出的MLR预测模型可以被看作是年平均每日卡车流量、交通速度、年平均气温和空气空洞百分比的函数。本研究提供了一种基于AASHTOWare PMED方法，并根据不同地区的投入水平，建立柔性路面性能预测模型的方法。
