Abstract AR
التشوه الدائم للترب السطحية هو تراكم التشوه غير المرن في الترب بسبب الأحمال المتكررة المستمرة الناتجة من حركة المرور.
الهدف الرئيسي من هذه الدراسة هو التحري حول بعض العوامل التي تؤثر في حدوث التشوه الدائم للترب السطحيه ألمعدله مثل : نوع المضاف، نسبة المضاف، محتوى الرطوبة، الإجهاد المسلط، وقت الإنضاج.
في هذا البحث تم استخدام نوعين من المضاف (سمنت، النوره المطفئه).
تم فحص مزيج تربه-نورة تحت تأثير ثلاث مستويات من الإجهاد المسلط kpa ) 42، 28،63)، ثلاث حالات انضجاج (٣ أيام تحت درجة حرارة C °٥٠،7 أيام تحت درجة حراره C ° 40، 28 يوم تحت تأثير درجة حراره C ° ٢٢)، ثلاث نسب من النوره (3 % هي النسبه اللمثالية لمحتوى النوره) ، ثلاث محتويات رطوبة مختلفة و كثافة جافه تمثل 95 % من الكثافة الجافة العظمى.
تم مراقبة التشوه الدائم خلال ٠ ٦ دورة متكررة و تم حساب التشوهات الدائميه المتراكمة.
Abstract EN
Permanent deformation of subgrade soil is the accumulation of plastic deformation due to continuous repeated loads from traffic.
The main objective of this study is to investigate some of the factors that affect the permanent deformation of stabilized subgrade soil such as additive type, moisture content, applied stress, curing time and additive percentage.
In this research soil samples were tested in the standard case without additive and with the additive, two types of additives have been used (cement and hydrated lime).The test procedure and test results conducted on original soil and treated soil are presented.
Soil-lime mixtures were tested under three levels of stress (28, 42, 63) KPa, three curing conditions (3days at 50°C, 7days at 40°C and 28 day at 22°C)with three percents of lime (3 % is the optimum lime content),at various moisture contents and dry density corresponding to 95 % maximum dry density .The permanent deformations are monitored during 60 load cycles, and the accumulated permanent deformations are determined.
