Reasons for the Repeated Repairing of Nowshera-Peshawar Highway GT Road

Roads are designed for a specific volume of traffic and load and beyond which it may fail. By crossing the elastic limit of the materials used in the construction of the roads. Over loading by commercial trucks in Pakistan is a serious problem. The heavily over-loaded trucks stress the road structure beyond their safe bearing capacity. As a result of which roads break up. The

Maintenance of Surveying Equipment - Routine Care and Transportation

Surveying equipment is being used under most stressful conditions. The equipment is exposed to extreme weather conditions, used in dusty construction areas and is subject to bumpy transportation. Proper care in the method by which equipment is used, stored, transported, and adjusted is a major factor in the successful completion of the survey. Lack of good

Retrofitting Techniques for Existing Damaged Buildings

Primary aim of strengthening a structure is to increase its load bearing capacity with respect to its previous condition. Only those aspects related to flexure are discussed here. Established techniques which have been in use successfully for a number of years are recognized as follows: Over Slabbing Sprayed Concrete with Additional Reinforcement Steel Plate bonding External Prestressing

Methods of Surface Treatment of Roads and Highways

Although the best type of surface course is pre-mix carpet for highway maintenance. The surface treatment methods are employed when: Intensity of traffic is not very high. the pro-mix mixers are not easily available due to long transportation or technical reasons. when the cost is high.

Road Maintenance - Highway Maintenance

Preserving and keeping each type of roadway, roadside, structures as nearly as possible in its original condition as constructed or as subsequently improved and the operation of highway facilities and services to provide satisfactory and safe transportation, is called maintenance of Highways or Road Maintenance. Surface maintenance

Munda Headworks Reconstruction on River Swat

The recent floods in 2010 have badly destroyed the headworks and causing a huge loss the agriculture potential of the area and country as well but due to strong struggle and insists of the people of shabqadar ( Merzai, Katozai, Mahzara etc). It was reconstructed in record time. If in case it was not constructed in time it may have cause a huge loss to the agriculture

Corrosion in Concrete Reinforcement

The basic problem in Reinforced concrete structures is the corrosion of steel reinforcement. The main cause of this corrosion is intrusion of water inside the RC structures. The corrosion of steel reinforcement can be judged by peculiar cracking of concrete structures. At last stage of corrosion, the steel reinforcement becomes exposed and the extent of corrosion

Precautionary Measures for Dams

Dams are considered to be a vital element for the economic and energy growth of any country. As compared with other sources of energy the Hydel energy proves to be more cheap and environment friendly. Being massive structures dams are needed to be deal with intense care and precautions in order to avoid any unpleasant event.
