“…Having a softer base allows the slab to "push in" to the base and deform, reducing the amount of stress induced and ultimately the amount of cracking (Reddy et al 1963;Eisenmann and Leykauf 1990a). For the case of traffic loading on a curled or warped slab, it is best to have a stiffer base, which will reduce the stress due to traffic loading, even though the stresses due to the curl will increase (Dere et al 2006). A stiffened base, such as an asphalt treated base, will prevent deflections, but also induce more stress in the slab than an ordinary granular base (Beckemeyer et al 2002)…”

“…Even if these analytical models are valuable for getting basic information, they cannot completely describe the behavior of a square concrete slab-on-grade, especially in the cracked stage. Nowadays, in spite of the several available numerical approaches [13,[37][38][39], there is still a lack of relatively simple numerical models aiming at taking into account both the concrete post-cracking behavior and the frictional effects at the contact surface between the slab and the subgrade.…”

Industrial pavements are thin slabs on a continuous support subjected to restrained shrinkage and loads. The use of fibers as an alternative reinforcement to steel welded wire mesh and rebars is today an extensive practice for the reinforcement of concrete slabs-on-grade. Despite the widespread use of fiber reinforcement, the corresponding benefits in controlling cracking phenomena due to shrinkage are generally not considered in the design process of Fiber Reinforced Concrete (FRC) slabs-on-grade. The post-cracking performance provided by glass macro-fibers at low crack openings is particularly convenient in structures with a high degree of redundancy. Referring to service conditions, it is well known that concrete shrinkage as well as thermal effects tend to be the principal reasons for the initial crack formation in slabs-on-grade. A numerical study on the risk of cracking due to shrinkage in ground-supported slabs is presented herein. Special attention is devoted to the evaluation of the beneficial effects of glass fibers in controlling cracking phenomena due to shrinkage. The numerical analyses are carried out on jointless pavements of different sizes. Since shrinkage stresses in slabs-on-grade are considerably influenced by external constraints which limit the contractions, different subgrade conditions have been also considered.

“…The revisions of the new 2002 AASHTO 'Guide for Design of Pavement Structures' are based on mechanical-empirical procedures. There are several advantages of mechanical-empirical procedures over the traditional empirical procedures which mainly enable (Timm et al 1998, NCHRP 2002 Dere et al (2005) studied the failure prediction of skewed jointed plain concrete pavements using three dinemtional finite elements analysis. This research was performed to determine if the frailure of skewed joined plain concrete pavements could have been predicted using a 3D finite element analysis.…”

This paper presents a simplified design procedure, which depends mainly on finite elements analysis considering the same input variables used in the traditional AASHTO empirical design methodology. The multiple regression equation developed considered the subgrade resilient modulus (Mr), Equivalent Single Axle Load (ESAL) repetitions, and the dynamic behavior of flexible pavements by incorporating vehicle speed. The outputs of this model are given in terms of structural number (SN) making it easier for the designer to deal with the various pavement thickness as per the traditional AASHTO procedure. Based on the model developed for static loading, SN values were approximately -6 to 7 percent compared to those of AASHTO design methodology depending on number of 18 kips single axle load repetitions. In the analysis of the dynamic behavior of pavements, SN dropped up to 30 percent for the practical design speeds that could be considered for pavement design purposes. تمثل هذه الورقة العلمية تصميم مبسط للرصفات الإسلفتية باستخدام العناصر المحددة بالإضافة إلى المتغيرات المستخدمة بالطريقة التقليدية لتصميم الطرق حسب مواصفات الجمعية الأمريكية للطرق والمواصلات AASHTO. المعادلة التي تم استنتاجها لهذا الغرض متعددة المتغيرات، وتشمل استخدام معامل القوة للتربة الطبيعية ((Mr ومعاملات تحويل المحاور للمحور التمثيلي، وكذلك سرعة المركبات على الطريق المقترح للتصميم. وقد أعطيت مستخرجات المعادلة بدلالة المعامل الإنشائي SN للتسهيل على المصمم لإيجاد سماكات الرصفة بالطريقة التقليدية المتعارف عليها. يتبين من نتائج هذا البحث لحالة التحليل الاستاتيكي أن النتائج كانت بحدود -6 إلى 7% من تلك النتائج المستخدمة بإتباع آلية التصميم الخاصة ب AASHTO وذلك معتمداً على عدد المحاور الفردية من نوع 18 Kips. أما بالنسبة للتحليل الديناميكي، فقد أظهرت النتائج أنها أقل بمقدار 30%، وذلك اعتمادا على مدى السرعة المتوسط لأنواع الطرق المختلفة.
