Ensuring A Smooth Journey Heavy haul truck drivers are responsible for transporting large, bulky loads safely and efficiently. It is their duty to ensure that these loads are handled with care and that all safety regulations are followed. As such, …
Road safety audit is the formal examination of existing roads, future roads or various sorts of traffic projects by any independent group of trained expertise. They examine the deficiencies in road safety. There are various stages of road safety audits. …
Pavements are in direct contact with the atmosphere and effects very extensively with the change in environmental conditions. To make rigid pavements safe against environmental fluctuations like freeze thaw effect, It is necessary to entrained air in hardened concrete. Entrained …
Stresses are the response of loading on the pavement. Material containing subgrade and environment condition are also responsible for stresses in the pavement. There are various types of stresses yields in flexible and rigid pavements under the applied live load. …
Flexible pavement differ from rigid pavement in terms of load distribution. In flexible pavements load distribution is primarily based on layered system. While, in case of rigid pavements most of the load carries by slab itself and slight load goes to the underlying strata. Structural …
From the word flexible, it is very clear that in this category pavement that come are those that deflects under the applied load. Flexible pavements are very dependent on the underlying layers, these underlying layers ( surface layer, base , …
From the word “rigid”, it is clear those pavements that are of a high strength. Rigid pavements are the laid surfaces that are constructed of high strength concrete on foundations having little resistance against live loads. Rigid pavements provides only …
Pavement is a hard, high strength top finished road surface that separates the underlying well-compacted foundation from the weight of vehicles. Pavement is in between the wheels of vehicles and the foundation of a road. Underlying foundation is mostly a …
Emulsion Emulsions are much more benefit than cutbacks. These are given below; Emulsions are environmental friendly. Emulsions have no effect on environment, because in emulsion there is no such diluent which has negative effect on environment. Emulsions are cheaper than …
Cutbacks are form by the combination of asphalt cement with solvent (kerosene oil, diesel, gasoline etc…). In cutbacks asphalt cements are mixed up with solvents due to the requirement of resultant less viscosity fluid, so that these can be used …
