Cost Effective Designs for Low Volume Sealed Roads in Tropical and Sub Tropical Countries
نویسنده
چکیده
Since 1994, TRL in collaboration with a number of road authorities and consultant partners have been engaged in extensive studies of the performance of low volume sealed roads within Southern Africa (Greening and Gourley, 1999). The roads included in service primary and secondary roads with ages varying from thirty years old to relatively new roads and specially constructed experimental sections. The roads examined were located in Botswana, Malawi, Zambia and Zimbabwe. The primary objectives of the studies were:

The cost-effectiveness of antenatal malaria prevention in sub-Saharan Africa.
Antimalarial chemoprophylaxis during pregnancy significantly increases the birth weight of babies born to primigravidae, but coverage in sub-Saharan Africa is very limited. This analysis assessed whether increasing coverage is justified on cost-effectiveness grounds. A standardized modeling framework was used to estimate ranges for the cost per discounted year of life lost averted by weekly chl...
متن کاملControl of Engineering Properties of Asphalt Concrete Based on Permanent Deformation Constraint of Subgrade at Tropical Zones in Iran (TECHNICAL NOTE)
The permanent deformation pavement of roads and streets at tropical zones Abstract (if layers are sufficiently compacted) is due to increase of asphalt layers temperature and consequential decrease of modulus of elasticity. Therefore, the asphalt mixture moves aside of the wheels of heavy vehicles and cause permanent deformations without volume variation. On the other hand, if the asphalt layer...

Background Since the global economic crisis, a harsher economic climate and global commitments to address the problems of global health and poverty have led to increased donor interest to fund effective health innovations that offer value for money. Simultaneously, further aid effectiveness is being sought through encouraging governments in low- and middle-income countries (LMICs) to strengthen...

Background & Aims: Cutaneous leishmaniasis (CL) is a vector – borne disease and at present it is one of the important health problems in tropical and sub - tropical countries including Iran. Due to imposed expenses to the people and government, this study was performed to evaluate the cost – effectiveness of cutaneous leishmaniasis treatment in the years after the earthquake in Bam/Iran. Method...
متن کاملEffect of Failure Criteria on Stress and Strain Analysis of Asphalt Pavement in Tropical Areas
A review of pavement thickness designs shows that two kinds of failure criteria are used in most cases. They are: 1) The tension strain under the asphalt layer that causes cracking and 2) the vertical compression strain on the sub-grade that causes deflection. In this study, various factors affecting thickness design are first defined and more than 216 pavement conditions are introduced. Struc...
