Ask ChatGPT about the research
يشكل الرصف المرن (Flexible Pavement) النوع الأكثر انتشاراً في انشاء الطرق في الجمهورية العربية السورية كما أنه يستخدم بشكل واسع في كافة مناطق العالم حيث تبلغ نسبة الطرق التي تعتمد في انشائها على هذا النوع من الرصف حوالي 93% في الولايات المتحدة الأمريكية ويعود ذلك الى سهولة وسرعة انشائه وصيانته . وهذا الانتشار الكبير للرصف يتطلب وضع منهجية للعمل في تصميم الخلطات الاسفلتية بحيث تحقق المتطلبات الفنية المتبعة في تنفيذ الطرق قادرة على مقاومة اجهادات التعب وحمولات المرور والعوامل الجوية . وفي بحثنا هذا قدمنا شرحا مفصلا عن مكونات الخلطة الاسفلتية وطريقة تصميم الخلطات الاسفلتية وفق خلطة مارشال . حيث قدمنا في الفصل الأول دراسة مفصلة عن الروابط البيتومينية وأنواعها وتصنيفها . أما في الفصل الثاني دراسة الخواص العامة للخلائط الحصوية المستخدمة في الطرق والتجارب التي تجري عليها وطرق دمجها . أما في الفصل الثالث والرابع تحدثنا عن مفهوم فلسفة الخلائط البيتومينية ومراحل تصميمها . وفي الفصل الخامس والفصل السادس ناقشنا الأسس النظرية لتصميم الخلطة الاسفلتية وفق طريقة مارشال . أما في الفصل الأخير تم تصميم خلطة اسفلتية تمثل المراحل التطبيقية لتصميم الخلطة الاسفلتية وجميع التجارب المنفذة على مكونات هذه الخلطة .

The Individual is the main entity of society, if he's in good health he's able to positively contribute to the development of the society, developed countries have recognized this fact, making it an interest in providing health care to the individual
, which is not limited to aspects of membership, but it also included the psychological aspects that become a most important aspect in health of the individual because of the increase of the destitute in the number of psychiatric patients, which coincided with technological progress and civilization so it led to a change in the concept of mental health care than it was previously, also led to changes in methods of treatment for psychiatric patients, and changes in the concepts of the place, which provides this health
care, the modern concept of building health care for psychiatric
patients must take into account the important role played by those buildings in the treatment, no longer seen as containers separating of these patients, but rather becoming more like living organisms that interact with them, they are affect them equally affected by them and through its behavior .
This study is devoted to the durability of bituminous mixtures,
including the effects of different gradations, compaction
temperatures and immersion time on the durability potential of
mixtures.
Playing is right for all children , and it's an important activity in their life, they
discover through it the world around them, and it was confirmed by philosophers,
psychologists and educators on the importance in children's lives and in their b
ehavior and
development. So we must provide spaces for children to play wherever they are, especially
in public parks, and must be given adequate attention and study according to international
design foundations, so check for children fun and interest together.
The research presents an analytical study of some of the children's playing spaces in
parks in the city of Damascus in order to verify the extent to which architectural elements
to the needs of recreational and development of children, from different age groups, and
through the analysis of the design elements of the samples studied and evaluated in
accordance with the recommended standards.
The recycled concrete aggregate RCA was able to take the place of the vierge &
natural aggregate NA, embankments elected,to implement the base&subbase road layaers
and airports in many country of the world.furthermore, there is almost consensus by
a large
of reshershers and scholars about the possibility of using RCA in mix cement concrete for
non-structural elements .whil,the using of RCA in the hot mix asphalt HMA still under
discussion and debate, due its high porosity , high water absorption, and its heterogeneity
which reflected negatively on the mechanical and physical properties of the HMA
This research discusses stadying the possibility of using the recycled concrete
aggregates in hot mix asphalt HMA, for the implementation of the bas layer bituminous
road , by the application of the marshall tests on hot mixtures asphalts have ben prepared
using different ratios of recycled concrete aggregates.
The results of marshall testes showed that the HMA prepared with amount of
recycled concrete aggregates less than 50%,can be used to implement the base layer
bituminous road,according to the general terms and specifications book for road works and
bridges in the syrien arab republic.
The study assesses the impact of economic factors in the geography
of services in terms of need, consumption and spatial organization are
topics and trends in a study in this new world.
These economic factors form a stand-alone system that belongs
to
the larger system that includes all the factors in the geography of services.
System of these economic factors is composed of the five factors that
constitute the elements of this system as follows :
1 - the geographical economic location.
2 - transport routes, and means .
3 - Capital .
4 - SOA (substructure of service) .
5 - economic resources and aspects of economic activity in urban
centers and regions.
Economic factors interact with each other within the system, and in
at the same time they interact with the system of human factors and the
system of natural factors for shaping the service sectors of the place by
showing the spatial variation in the needs of the population to services
and they use them, and its spatial organization of place in urban centers
and regions.
Economic factors are different in the strength of their impact in this
variation and spatial organization of the services sector of the population,
depending on different areas or trends in the study in of the geography of
services, and the first trend studies the needs of the population is services.
The quality of these to services, and the second trend studies
consumption of the population to these services, and the third trend
studies the spatial organization of the services sector of the population.
A system of economic factors forms inputs which interact together,
and at the same time interact with the system of natural factors and
human factors, to give outputs that show the nature of services for the
population and the characteristics of its distribution and development in
place .
