Drainage discharges from any hard surfacing where there are vehicles can be a problem to keep clean. This is done with the use of separators. Separators are a major component in any SUDS (Sustainable Urban Drainage System) approach to drainage design. Car parks and other areas where cars and other vehicles are stored are at…
Construction techniques used today should focus on protecting the environment and decreasing pollution to slow down the impact of global warming on our environment. Green building techniques are helpful in maintaining a healthier society and surroundings. Construction methods Construction is the process of creating a new building or structure by using natural and artificial resources…
A provincial long-term performance program was implemented at MTQ in 1992. Its main objectives are to improve pavement life and performance as well as to optimize the use of the funds allocated to the construction and maintenance of the road network. Our will to improve our practices and the various steps taken to meet the…
Construction of CRCP is similar to that of other concrete pavement types. Planning and execution are crucial since errors made during these stages can be detrimental to the overall success of the project. It is important to pay special attention to certain details such as the selection and installation of the reinforcement, the carrying out…
2.1 Design Aspects: The volume changes stresses in CRCP will be taken care by providing sufficient reinforcement to keep the cracks tightly closed while maintaining adequate pavement thickness to counteract the stresses produced by wheel loads. CRCP allows the concrete to develop very fine transverse cracks that seem to be uncontrolled and random. The spacings of transverse…
Abstract “Continuously reinforced concrete pavement” as the title suggests this type of pavement is reinforced throughout in longitudinal direction. This type of pavement has no transverse joints unless and until there is end of pavement or the pavement comes in contact with some other pavement or bridge. A longitudinal joint exists only if the road…
The collapse of the World Trade Center (WTC) towers on September 11, 2001, was as sudden as it was dramatic; the complete destruction of such massive buildings shocked nearly everyone. Immediately afterward and even today, there is widespread speculation that the buildings were structurally deficient, that the steel columns melted, or that the fire suppression equipment failed…
FLOOR SLABS Treatments for conventional flat slab design are as follows: 1. More attention must be paid to the design and detailing of exterior bays and lower floors, which are the most susceptible to blast loads. 2. In exterior bays/lower floors, drop panels and column capitols are required to shorten the effective slab length and…
ABSTRACT: All western democracies are now acutely aware of the apocalyptic consequences of a well-orchestrated attack on high-profile government facilities and other related targets. Many of these buildings are historical, ornate, listed and constructed using traditional techniques. Many of the modern retrofitted reinforcement techniques used to protect these structures against terrorist attacks are unsightly, intrusive…
